Best Hydroponic Systems for Growing Cannabis: Reviews

Growing marijuana using hydroponic systems has always been helping cultivators grow their marijuana faster than using the traditional soil method. It’s usually difficult for beginners to grow hydroponic weed, but once you get the hang of it, you will see how amazingly you can grow bigger plants faster with minimum effort.
It is recommended by many growers to start practicing before you try it. For example, you can start by planting cannabis plant in soil and grow it that way to get the feel of it. Or you could also grow something like lettuce or tomatoes or spinach hydroponically as a test. So I will start with the things that you need get started with your hydroponic setup and then list out the best hydroponic systems for growing weed.

Following are the things that you will need to grow cannabis in a hydroponic garden:

1. You will need a space to grow your cannabis, like a grow tent
2. Lights or lamps that can impersonate sunlight
3. Soil like coco coir or peat
4. Flower or vegetable Pots
5. Nutrients for your plants
6. pH tester for checking acid levels
7. Timer to control the lights
8. Proper ventilation if you use hot lamps like HPS and if you also need to control odor.
9. Seeds or clones

Depending on factors like strain and how healthy the plant is, each plant that you grow will result in a couple of ounces of marijuana,
Let me quickly first run you through the basic necessary process of growing marijuana quickly.

The growing process for any marijuana species is almost the same – whether you choose the favorite Sativa for its high effects, or Indica for its calming and healing power. You might have to clip the top of an Indica to make it shrub out more, but how you water and feed both these kinds of plants is the same. First, check the temperature in your grow room and make sure that it is between 80 and 85 degrees F (not more than 90 degrees), as that’s the optimal temperature for growing cannabis. Second, use filtered water to water your plants so that you avoid feeding your plants with chlorine and fluoride. Also ensure that the water is slightly acidic, with a pH value between 5.5 to 6.5, with 6.15 about right. Third, comes the lght system that you will use. You need to determine the color and temperature of light before choosing a lighting system. Various colors ranges will have various impacts. You can get help from CCT (correlated color temperature) to determine as CCT rating tells the magnitude of the temperature of HID fluorescent lights. Simply follow the instructions of the light system that you have keeping in mind the proper height and coverage. Hang the light in such a way above the plant keeping in mind the correct distance so that the light reaches out to all the corners of your grow area. A grow tent lined with Mylar can help reflect the light back onto the plants. Once the plants are in the flowering stage, identify the sex of the plants and separate the males and females because if you aren’t trying to get seeds, you shouldn’t let them reproduce. Females will have distinctive white hairs on them and males will have balls. Get rid of the male plants because you cannot smoke them, they’re only good for pollinating. Also, keep in mind to cut off supplementing the plants with any nutrients at least before two weeks of harvesting. Just keep watering the plants usually, don’t overdo it. This will help in cutting down any nutrient flavoring. When the time for harvesting comes, trim the plants with a bud trimmer or by hand and then dry them. Leave the dried buds in an airtight container for about a month to cure.

Types of hydroponic systems for growing marijuana:

Deep Water Culture, also known as Hydro Pots: Hydro pots are cheap and easy to put together and use, especially for beginners. It consists of three parts:

1. A bucket or reservoir for storing the water-based nutrient solution.
2. A basket or mesh stuffed with peat or Rockwool soil. This is for the roots to grow through and reach down to the nutrient solution
3. An air stone, similar to the ones in fish tanks to provide air to the nutrient solution.

For each plant you plan on growing, you will need one Deep Water Culture unit. One per plant. There would be a five-gallon bucket with nutrient-rich water at the bottom, a basket filled with peat moss or clay where the cannabis will be planted and the air stone bubbling down inside the liquid at the bottom. If you have more than one plant, you have to link all these individual buckets with irrigation pipes or tubes into a single reservoir that sends the nutrient water out to each plant. You really need to be careful about two major things: contamination and stagnant water. Make sure to protect the nutrients at the bottom of the primary container from light and contamination, and also ensure that the air stone doesn’t stop working.

Please find below an example of a good Deep Water Culture system for a beginner.

General Hydroponics Waterfarm

The PowerGrow System comes with the following features: 1. A FDA-approved food safe 5-gallon bucket 2. A basket lid 3. An air pump 4. Air stone 5. Tubing and 6. Rockwool plugs as a growing medium.

This Deep Water Culture 5-gallon bucket kit is a perfect model for larger kinds of cannabis plants. It takes up a lot of floor space but handles huge tension like Big Bud and Brian Berry Cough. Additionally, it also comes with a water level marker and a bucket drain and the best, a 1-year warranty. One note of caution—when Rockwool can be irritating to the skin when dry, use gloves to handle until it’s properly moistened.

AutoPot 4pot System Gravity Fed Watering System – Hydroponics and Traditional Gardening

How to grow weed indoorsBuy from Amazon

AutoPot comes with a large 12-gallon reservoir and 4 smaller pots that hold 3.9 gallons each. It doesn’t have air stones or potting medium, but you can add those as per your requirement. The setup here is gravity-fed, so it sends nutrients to the plants only when the plants have used enough in its own pot to make space for more.
Even here, you have to make sure to avoid any contamination in the central reservoir to prevent the plants from suffering.

Besides Deep Water Culture systems, the second way to grow with hydroponics is Ebb and Flow, also known as Flood and Drain.

Ebb and Flow systems soak the roots of your plants with water and then drain the water away. So you don’t have to worry about using air stones because the water doesn’t stagnate at all. Sometimes a timer will come with the system, but if it doesn’t, then you will just need to get one. Again, keep an eye on any contamination in the central reservoir. Else all the plants will suffer.

Viagrow V4X4COMP Ebb & Flow Hydroponic System Tray, 4′ x 4′

How to grow weed indoorsBuy from Amazon

This Viagrow model is a four-foot by four-foot Ebb and Flow System and it comes with a tray and stand, potting medium, timer, pump, and tubing. There are 25 pots included in the box that can hold one gallon each, but you can replace them with larger pots also if you want.

The Viagrow manufacturer also sells smaller setups. The smaller setups come in handy because many jurisdictions have limited the quantity of cannabis a person or household can grow.

Top Feed

In Top Feed systems, the nutrient solution is held in a reservoir like Deep Water Culture systems. A pump on a timer comes on periodically and sends nutrient solution through a mesh of spaghetti tubing which opens out at the roots of each plant. The excess water that is drained away at the bottom of the pot is collected and sent back to the reservoir for the water to be reused in the next round of watering. Keep an eye on the functionality of the pumps, ensure it doesn’t break down. If it does, then the plants will lose out on water and die thirsty.

Nutrient Film Flow Technique

Nutrient Film Flow Technique is widely popular with hydroponic growers especially because of its simple design. Instead of using moss, clay, or Rockwool as the soil, these systems use something called a capillary mat. These mats are porous, and they keep the nutrients regularly circulating in the roots. The plants get fed, but not drowned, and nothing gets stagnant.

Aeroponics with Misting

Aeroponics is one of the most technical systems of hydroponics. With this system, your plants will have rainforest like atmosphere. It isn’t an excellent choice to grow plants in a closet or spare bedroom with this system. You need to have a good isolating grow tent to grow plants this way.

The roots of the plants get misted periodically while the plants hang in baskets or pots. This helps in growing the plants really fast, but you have to monitor every day very carefully. The pH level should be monitored and also keep an eye on the right mix of nutrients for the plants; else the consequences won’t be excellent.

General Hydroponics RainForest 66 Aeroponic System for Medium to Large Size Plants

How to grow weed indoors   Buy from Amazon

The RainForest 66 Aeroponics System comes with a 17-gallon reservoir, a sprayer, six plastic containers with CocoTek liners, and a 3-Part Flora Kit. It is an easy all-in-one setup to grow your weed. The nutrient solution is also aerated by the system before spraying it over the plant roots. You need to be careful and keep a watch for parasites like aphids if your setup is not isolated from pests. Another thing to consider would be the size of the pots—they are only six inches in diameter.

Growing mediums for hydroponics

There are different kinds of soils available in the market that you can use instead of real dirt usually used for cultivation. Many experienced hydroponic growers choose these materials for growing their plants. Listed below are the materials:


Peat is a popular choice among growers to be used as a base for growing because it is not expensive and is loaded with minerals. The most common types of this variety are peat moss and humus.

Sphagnum moss

Sphagnum moss is the type of moss which is the slowest to breakdown. It is lightweight and also carries a lot of water. It is a very good option for hydroponics but is more expensive than peat.

Coco coir

Coco coir is a by product of the process of coconut husking (it is made from shredded coconut husk). It usually tends to be more fibrous than the commercial peat. It’s high-absorbent and has an excellent ability of retains water or moisture for the plants


Rockwool is made by spinning molten rock similar to the process of making cotton candy, thereby providing a sterile and fibrous growing medium. It is also known as mineral wool and is spun into fibers and then finally formed into cubes or slabs which have the capacity of holding around 80% of moisture. It retains water and at the same time lets air to penetrate the roots of the plants. It’s alkaline, so make sure that you treat it before using it.

HEC (hardened expanded clay)

HEC pellets are an excellent choice for hydroponic systems because it drains well and lets the plant roots get enough oxygen. They don’t have much nutritional value though like moss.

Vermiculite and Perlite

Vermiculite is used as an additive for soilless mixes, it is a mineral and holds moisture and nutrients very well. Perlite is also an absorbent additive which is mixed with coco coir and peat.

Tips from experts for you to grow healthy plants using hydroponics:

  • Water your plants every alternate day when they are young and then water them just once a day when they are in their flowering stage.
  • Use a hygrometer to keep an eye on the moisture levels. Water your plant when the potting substance feels dry on the top.
  • The leaves can show signs of too much or too less water. See if the leaves wilt or drop and water or don’t water accordingly.
  • Some leaves turn yellow and fall-off during the plant’s vegetation stage. You should stop giving nutrients and just keep watering because you will need to start harvesting in a couple of weeks from then.
  • Start harvesting when one-half or three-quarters of the white hairs have turned yellowish brown. Late harvesting makes for more relaxing marijuana.
  • When trimming, don’t leave the leaves because they can be used in making cannabis oil or butter.
  • The buds are dry enough when they snap off easily instead of bending.

How to test pH acid levels

Ensuring the correct amount of acidity is very important for growing healthy cannabis plants. Having the right pH will help in the proper absorption of nutrients.

The pH value of soil ranges from 1 to 14 with (1 is very acidic, 14 is very alkaline, and seven is neutral). The ideal pH value for growing weed hydroponically is 5.5 to 6.5, just a bit acidic. (In dirt, the pH value should be between 6.0 and 7.0.)

You can test the levels in —the nutrient solution and the soil or medium where the plants are growing. You can use the following tools for testing the pH level:
A tester pen
A liquid solution

Easy fixes for pH levels that are too acidic or alkaline

An easy-to-use pH Control Kit is sold by General Hydroponics which even includes a pH tester, so you don’t need to buy an additional one.
pH levels can be fixed or adjusted with household items like baking soda and vinegar, but these methods are not recommended for new growers, only experienced growers should use such stuff to tweak pH levels.

Ways to stop root rot:

What is root rot? Root rot is a condition that is seen mostly in indoor growing plants that arise from poor drainage. The roots of the plants start rotting. It is a fungus that spreads quickly through all plants on an interconnected system. You’ll see signs like withering leaves turning yellow, and the roots will not look white/creamy and healthy, they will look slimy, brown and smell terrible like mildew or rot.

Some tips on preventing root rot are by making sure that you don’t overfeed or water your plants. Keep water temperatures below 72 degrees. Keep the growing area clean – clean your system according to the manufacturer’s instructions. Remove dead plants. Ensure to protect your grow area from light and too much heat. Make sure to seal the area properly as that will give fungus hard time to spread or invade. If you are growing many plants, make sure to remove and unhealthy or affected plants to prevent the infection from being passed on to the other plants. Be cautious if you are using Hydrogen Peroxide as it kills most of the good bacteria and is hard to monitor and use.

You can try adding beneficial root bacteria to your nutrient solution to prevent or treat root diseases. Some of the formulas available in the market are as follows:

VooDoo Juice
Great White Root Powder
Subculture B

I have used Hydroguard personally, so recommend to use this as it is inexpensive and can last you throughout your grow.

Also, make sure to supply your plants’ water with as much oxygen as possible. So plan to invest on air pumps and air-stones for your hydroponic system so that you can dissolve more and more oxygen in your water. Over of this much won’t affect your plants in a bad way at all. You can use the following for supplying more oxygen by supplying more bubbles:

EcoPlus Eco Air 2 – Two Outlet 3 Watt 126 GPH : It’s an air pump with two outlets
EcoPlus 728405 Round Air Stone, Large
Flexible 3/16-Inch,26-feet Aquarium Airline Tubing with 6-Pcs Suction Cups – It is a standard aquarium tubing to hook everything together

Nutrients for healthy cannabis growth

Nutrients are extra supplements for your plants for healthy growth. One of the best products is from General Hydroponics. It’s an excellent product for people who raise herbs for essential oils, too, because it’s all organic.

Top Inline Fans for growing cannabis indoors: Reviews of the best inline fans for your grow garden

Inline fans are crucial for growing cannabis in a tent or grow room. If you use the right types of equipment for growing indoors, it will let you have more growing seasons per year, hence providing the ability to produce more quality plants. If you supply your grow room or grow tent with inline fans, it will help you provide perfect ventilation for your cannabis plants. The many advantages of proper ventilation are that they help remove CO₂ exhausted air and therefore keeps humidity levels stable. They also assist in regulating the temperature of your grow tent by keeping your grow space at a right temperature helping in avoiding burning of your cannabis plants. Lights that you use will create heat which will eventually burn your plants if you don’t dissipate the heat properly. Inline fans are efficient in taking away excess heat with all of the air circulation and exhaust system that they have.

Factors to pick the Right Size Fan for your grow garden:

It is very critical to consider the size of the area that you are using to grow your cannabis plants while selecting or choosing a fan. The way to find the best inline fan with relevant capacity is by multiplying length x width x height (in feet) with 125% (1.25). The extra 25 percentage lets you have some extra space in case of resistance from carbon filters or ducting. This number that you found is the capacity of your fan – the quantity of air your fan would be able to remove per minute.

The next important factor in choosing a fan for your cannabis grow room is the type of lighting system you are using. Few types of light generate more heat than the others, which require more airflow to evaporate. An example would be, if you are using HID lamps, you would want to opt for a higher CFM fan because these lights create more heat than LEDs. You now know what to look for while purchasing an inline fan.I have listed below the best inline fans for growing weed indoors in a grow room or grow tent. You can choose which the best one from below according to your requirements.

There is evidence that Marijuana is useful for relieving severe pain, nausea, and other chronic conditions. However, there are also numerous health concerns that arise from taking Marijuana. So, I insist on growing responsibly.

A few infos on Marijuana:

Marijuana (Cannabis Sativa, basically a hemp plant) is also known by many names such as weed, herb, pot, grass, bud, ganja, Mary Jane, 420 and a vast number of other slang terms.

It is essential to focus on the quality of the conditions in which you will grow your marijuana since these factors will affect the quality of the grass that you harvest, such as effects on the body of the inhaler, taste, aroma and power.

Steps of growing marijuana:

Coming back to the main point of the article, I am going to illustrate in details a step by step guide on how to grow marijuana indoors. Happy reading!


How to grow weed indoors?

Healthy parents make healthy babies – this holds true for seeds too. Healthy plants only will produce healthy and quality seeds. Features of plants like the height, length, color, scent, and quality – all depend on the seeds.

You want to get the best of marijuana after working hard on growing the stuff, so make sure that you select the best quality seeds for your crop to yield the best harvest. While choosing your seeds, be always sure to select the seeds that are hard and light brown in color. Green & soft seeds aren’t mature or ready for germination. Only a healthy and strong seed can yield great results.


After selecting your seeds, you will proceed with germination. Germination is the process of the growth of a plant contained within a seed; which results in the formation of the seedling. Here a healthy and mature seed is kept in certain environmental conditions to break down and produce a seedling. However, you should know that only 2 out of 10 seeds will grow to become healthy female marijuana plants, while the others may spoil or grow as male plants.

In the process of seed germination, the seeds must be provided with moisture, air and heat. After germination, you need to remove all the unnecessary male or less developed sprouts and focus on growing healthy female marijuana plants.

A healthy seed takes on an average of about 2 to 7 days to germinate. But the period may vary by different factors such as the quality of seeds, temperature, moisture, etc. Farmers take the germination session twice to get more female plants. Best suggestion is to germinate in the hot months since it will bring you more useful results. Grower mat might also work, but it is not that budget friendly. Moisture, heat and air – when seeds are supplied with these nutrients, they start germinating, and the white colored sprouts keep growing longer and longer. As soon as the size of the sprouts reaches up to about quarter an inch, you know it’s the perfect time to shift these germinated seeds to other mediums such as rockwool tray or pots where it will grow to become a baby plant and then it can be shifted to a garden or hydroponic system.

Different steps on germinating seeds:

You can follow many processes to germinate your seeds, but a main suggestion would be to try and germinate other seeds before germinating your costly marijuana seed, as you obviously wouldn’t want to waste your seeds. Listed are different techniques for germinating seeds:

  • Soaking:

This is one of the most popular ways of germinating seeds. What you need to do is fill a container with warm water. Remember not to make the water too hot. Put the seeds in the warm water and observe if there are seeds which start floating on the top. You should then remove these floating seeds because the most viable seeds will not float and remain at the bottom of the container. You can then cover the container with a lid in such a way so that no light can reach the inside of the cup. The seeds will within 48 hours or so; some seeds might even sprout just within 24 hours, although it depends on different factors.

  • Germination in Soil:

This process is also one of the most popular and traditional ways of germinating seeds since this method is easy, and it actually works. Take a pot with a hole at the bottom of it- fill it with soil, pour water in it and let the water drain from the pot through the hole at the bottom. Then dig soil from the surface and let a pencil or any other pointed tool go beneath a quarter of an inch, put the seed in and then refill the space with soil. Spray water and keep the soil moist at room temperature (around 78 degrees Fahrenheit) unless you see a small sprout coming outside. With this process, the seeds might take around 5 to 7 days to germinate.

  • Paper Towel Method:

A couple of dishes, a couple of paper towels and water are all you need to grow your seeds using this method. Heat some water and bring it to boiling point, then use the boiling water to rinse both the dishes so that there are no germs left. Then soak the paper towels in hot water and squeeze to make them damp and warm. Now, place one paper towel on a dish, put some seeds on it, cover them with the second paper towel and then cover the seeds up with the second dish. This will help resist sunlight or any sort of light to enter in this environment. Usually, seeds take 2 to 5 days to germinate through this process. You should not leave the germinated seeds on the towels for too long, remove them from paper towel as soon as you see the sprouts.

  • Propagation Kits:

Propagation kits are designed for yielding good results for germination of seeds and is inexpensive. In this method, you have to pour the seeds from tiny holes, then add the germination hormones which comes with the kit, and then the process gets started. You know when to take your seeds out; when you see the sprouts.

  • Germinating in Peat Briquette: This is a very easy, safe and reliable method of germinating marijuana seeds. You need to soak a peat briquette in water and let it swell. Now, push a seed into the hole and keep it at a warm temperature of around 95 degrees Fahrenheit. Keep them moist and wait for the sprouts to come out, then shift the sprouts somewhere else for growing the plant.

You can select any of the methods mentioned above of germinating seeds depending on what suits you the best.

Seedling : Growing seedlings

You have come to know a bit of how to grow weed indoors. Now, once you see that your seeds have sprouted and are about a quarter of an inch long, then you know that it is time to replant it in a pot and let it grow up to become a small marijuana plant. A seedling of marijuana is a pair of two leaves that are generally called “seedling leaf” or “cotyledon”. The cotyledon initially stores food and helps in growing a healthy plant. When real leaves start growing in the plant, cotyledon turns pale yellow and then falls off. A baby plant needs an intensive care at this stage. Make sure not to water the plant too much; it is one of the biggest mistakes that most of the beginners make with their cannabis seedlings. The amount of light the plant receives should also be given importance as this is a critical factor.

I want to tell to the newbie growers especially, that the growth of plant at this stage will appear slow and it’s ok. Don’t get tensed about it. It is actually developing from inside; the roots are developing, so the growth of the plant looks slow. Do not try to over fertilize or over water the plant too to increase its growth rate. It can have disastrous effects on your plant and eventually kill your plant. Also, feed your marijuana seedling with light; they require approximately 16 hours of light on a daily basis.


The next step to grow your cannabis plant would be to transplant it. However, you managed to grow your seedlings, now its time to transplant those seedlings into your indoor grow garden or hydroponic system, where your plants will have to grow up to produce some best quality weed out of it. For transplanting the seedlings, you should first dig holes in the soil and then place the seedlings carefully inside. If you drop the seedling along with Rockwool tube, it is okay, as it never affects the growth of a plant in any manner.

The growing phase

Now that the plants are growing, you need to pay attention to a few important things. The first and foremost thing to focus on is the nutrient deficiency or efficiency. Both of these usually have the same symptoms. The period between 3rd to 5th week of your plant growth could be the best time to understand if the plant is growing healthily or not. You will know that the plant is growing the right way if the color of your plant is green, branches are strong and dense, and all other things are looking fine.

A few stems of the plant in its early days could appear purple. You don’t have to worry about it since it is not an abnormality, it is a normal thing. Genetics happen to cause this purple color, nothing else. Try and regulate humidity if you are growing plants indoors. High humidity aids in escalating or increasing the growth rate of female plants while low humidity is good for the growth of male plants. The same thing applies to temperature as well. Low temperature is helpful for female plants’ fast growth while high temperature is right for male plants. In the case of lighting, blue spectrum light energy stimulates the growth rate of female plants and red spectrum light stimulates the growth rate of the male ones. Lower nitrogen levels are suitable for female plants while higher levels of nitrogen nourish male plants really efficiently. Similarly, you will have to keep the potassium level low for female plants while for male plants, you will have to keep the potassium level high.

How to Grow Marijuana? (Guide for beginners)

You will now learn about the most important topics in more details that will help you become a perfect marijuana grower. You can select any method and medium you choose to grow your indoor marijuana, depending on your feasibility, needs, etc. Following are the processes from which you could select one or more:

  • Growing with soil using germination process
  • Growing by cloning Process
  • Growing hydroponically

The most trusted and popular methods of cultivation are with soil. So, I would recommend newbies to go for growing with soil. Reasons are: it is a very cost effective way and has fewer risks when compared to other processes. But, it is entirely up to you if you want to grow your crop indoors or outdoor. I will now write down a detailed guide to all these methods of growing cannabis so that you know and understand what method suits you the most and why.

Growing with Soil Using Germination Process:

I have already mentioned above in this article the reasons why growing cannabis with soil is better than other methods by far. Reasons are: it is cost effective, high-yielding, reliable, and most preferred way of growing your own marijuana by far. But for beginners, it’s relatively easy to grow in containers and has fewer chances of failure. You also might not have plans to grow this to a large business, so you may choose to grow in containers.

Growing in Containers:

The advantage of growing your marijuana in containers is that you will be able to look after each plant individually and pay particular attention to them. That way, you’ll be able to identify the rotten or under grown cannabis plants. You can use anything as a container: a pot, small bucket, wooden box, etc. and make some holes (about 1 centimeter sized) at the bottom of the container to drain out excess water. Remember that the color of the container should be dark, you could also paint it black as it is the best option; it helps in spreading the light to the depth of roots. You can plant your cannabis in smaller containers in the beginning since they are much easier to handle, but as the plants start growing rapidly, you need to shift them to bigger containers because the roots of cannabis are very long. I have seen and heard that many growers or farmers grow their plants in small plastic shoppers in the beginning as it is economic and then once the plant grows big, they are shifted to other appropriate sized containers. You can also make your own container by using old and rejected pots, wooden boxes, big sized bottles or bowls. Just make sure to clean them first and then make properly sized holes at the bottom of the pots so that they are big enough to drain all the excess water out.

Growing in the Ground:

You might not be able to find a place at your home where you can grow marijuana in the ground, plus where you will have abundant sunlight to hit the area, especially if you are planning on growing marijuana indoors. But if you have a place, then you should utilize that area and start growing weed in it. Just be cautious about the spacing of the plants – try and leave proper and uniform space after each plant so that you could boost the efficiency of your plants.

Some Necessary Information

If you are planning on growing marijuana on soil, you need to make sure that you choose the right soil for the healthy growth of your cannabis plants. You should choose it right. Make sure that the soil doesn’t drain out all the water. It should be drainable, but it should also retain some water without letting them all drain out. The most important factors to keep in mind while selecting the right type of soil for marijuana are PH level of the soil, nutrients, and texture. Organic soil is suitable for growing everything, the same applies for growing cannabis plants. It has what it takes to produce the best quality marijuana crop. The texture of soil also plays a significant role in growing marijuana, so make sure that the soil is fluffy, light and can drain the water but retain some as well.

Transplanting of Plants:

As I have stated earlier in this article, transplanting means shifting plants from small containers to bigger ones or moving them to the ground of your cultivating area if you have one. The method of transplanting a plant is easy, but it’s a bit tricky too. Please make sure that you take the plant out of the container very carefully along with the roots also holding all the soil together. Do not remove the plant without the soil by just pulling it out. That way, the roots will be strained and damaged, and your plant might not grow well. First, dig a hole and then shift your plants. Usually, transplantation of a plant causes a little harm to the roots of the plant, so it needs some time to settle. Try if you can, to transplant at night so that it has enough time to rest before starting to function during the day time.


Below are the primary nutrients which play a major role in the growth of cannabis:

Nitrogen: Nitrogen is one of an essential element that acts as leaves and stems growth stimulant. So make sure to supply your plant with enough nitrogen. Nitrogen deficiency could lead to the plant’s leaves turn yellow. Use as much nitrogen as you can especially during vegetation to ensure the smooth growth of your plant.

Phosphorus: Phosphorus is one of the major nutrients which play a key role in the process of photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants. It is recommended to use more phosphorus than nitrogen during the flowering.

Potassium: Potassium is necessary for building and transferring sugars in cannabis plants. It also serves as an essential element for absorption, aiding and rapid growth of the plant. Leaves with a potassium deficiency get yellow, brownish, or appear to have burnt tips around the edges.

Water: When it comes to watering your marijuana plant, you must take two factors into account: The size of the container and the light’s intensity. HED lights affect water level in the plant due to the high degree of intensity that they have. You need to water your plants every other day because along with water, roots need some air too. So keeping your plant a bit dry is okay. But not too much, since the plant might suffer from dehydration.

pH Level: This is really important for you to monitor carefully, especially for your cannabis plants. The best pH level for the survival of your marijuana plant is 6.7 to 6.2. If you ignore the pH levels, then it can lead to the devastation of the whole crop.
Putting too many fertilisers and organic compounds may disturb the pH level in a plant. So please do a thorough research before using any fertiliser on your plants. It is suggested that using normal manure as fertiliser is just fine for marijuana. You don’t need to find some extra-ordinary fertiliser to feed your plant with.

The method of Cloning:

Since we have already discussed how to grow marijuana from seeds, it’s time to move on to another process of growing cannabis plant. The cloning method is also known as one of the best methods of growing weed, and it’s also used widely by cultivators and also indoor weed growers. To get started with this process, first, you need to select a few donor plants, cut their shoots and branches, plant them in a separate medium and let them grow there. It’s assured that all the plants whose clone has been taken from a mother plant will turn out to be females. And you know for sure how good female plants can be for producing weed.

Why is cloning such a famous process and why do many growers and cultivators use this? That’s because it has many advantages. Although it has a few drawbacks too, like any other method; I would still highly recommend you try cloning if you already have some healthy and productive marijuana plants in your grow area. You can just select a few donor plants from the existing ones in your garden and then make some clones from them.

Listed below are a few pros and cons of cloning:

The advantages of Cloning-

Cloning can save you a lot of time as compared to growing with seeds all over. Because all that you need to do is select a few plants, make a few clones and then place them in their growing mediums and let them grow. Whereas, in the method of growing with seeds – it takes days in germination, the growth of seedling, and then becoming a plant. Another advantage is that it saves your money as well because you don’t need to buy seeds if you already have a few plants, you can just take clones out of them. It’s assured that you will get female plants as a result. In this method, plants also start producing the weed way earlier than that with the seed method as rooted clones of marijuana take very less time in flowering. The characteristics of the produced weed will be the same as the mother plant or in some cases, even better in the context of taste, aroma and after effects.

Drawbacks of Cloning-

The main disadvantage of cloning is genetic uniformity. Lack of genetic diversity could lead to more chances of the clone plants to get infected with insects, pests, viruses and other diseases. That is because these plants will have the same weaknesses as the mother plants. The other disadvantage is that, with cloning, you will have the same taste, fragrance and after effects as that of the mother plant. This way you might end up missing the variety you would have gotten if you went with the seed process where you would be able to select seeds with different taste, aroma, and other features.
Another thing with clones is that you should always find clones from your existing cannabis plants. That way you will be assured that the clones are reliable. Whereas, if you get clones from other sources, you don’t know how the resulting weed from that plant will be like. It will be like a shot in the dark. Also, clones are very sensitive and are not that easy to handle. At the slightest mishandling or rough handling, they might die out of shock.
Since all the clones are always going to be females, the breeding process in the future could turn out to be difficult.

Steps on making clones:

The first step is to choose the mother plant. Make sure to choose a healthy, productive and disease free plant to make your clones.
You should make 50% more clones than the number of plants that you want to grow. That’s because all the clones are not going to grow to become healthy plants. Most of them may die due to several reasons. The best time to cut the clones is before the plant starts flowering. Keep your hands clean. All your tools and growing area must be clean too, remove all the dirt.
Before planting, pH balanced medium should be ready too. Have all the clones within you immediate reach at the time of planting them.
Select the suitable clones (shorter clones are usually the more preferred ones, having two to three nodes only). Treat your clone with a rooting solution fungicidal-b1 mix because it can help create some extra potential that will help in growing a healthy and fruitful plant.

Next steps would be to put these clones in rockwool cubes.
Remember to soak the rockwools over night in a pH balanced solution. The next step would be to figure out dome and lighting. You need to spray the inside of the humidity dome with a no damp-solution. Do not spray the solution on to the clones directly.
Place the covered clone tray along with the humidity dome at a place where a suitable amount of white fluorescent light is available. This could be natural sunlight or T9 grow light or may HID light. Remember to uncover the clone tray daily for air-circulation. However, the humidity dome should be removed on the 5th day. Then you have to check if the plant started growing roots or not. You could check by tugging the plant slightly upwards. If the plant has roots formed already, it will not come out of the cube. And if it hasn’t developed roots, then it will come out of the cube very easily. Remember that you are supposed to check this only on the 10th day. And be gentle while tugging the plant. Don’t be too rough. The roots might break off if you pull too hard.
Don’t worry if you see some leaves turn yellow during this phase. It means the plant started growing roots and during this process, plant consumes all the nutrients from fan leaves. So it is actually a good sign. As the process of rooting continues, you have to spray it with water every once in a while. Once you receive signs of plants being rooted, you are supposed to water them properly and drain the rooting solution out of the cube as it would be of no use at this stage. During this critical phase, check if the plant is wilting. You can check it by opening the tent a little bit, and if you find no wilting for 4 to 6 hours, it means you should proceed to the next step. You can now transfer these clones to the HID lights, or you can plant them in the soil. Ensure that they get 15 to 18 hours of light. They need this much light to get to the vegetation phase. Also, don’t worry if you find your clones wilting, just check if they are placed properly in their respective mediums. Keep a look on the light as well; it shouldn’t be too bright and should be adjusted according to the need of the plant.


Hydroponics is also used widely by many growers because of the big yields that they give. But like any other method, it has it’s own set of advantages and disadvantages.


You do not need soil in this process of growing hence making it a cleaner way of growing weed indoors. People who do not like to deal with dirt like this process very much because it’s less messy.
Because it’s a controlled system, it leads to lesser pollution of the environment. It also generates a high amount of quality weed.
No dry spots and root drowning are observed because of the controlled system of hydroponics. Less water needs to be used hence cutting down water cost because water is already available in the system. Nutrients are also under the system, so it saves you some money here as well. It’s easy to prevent hydroponic system from getting infected or attacked by insects since the plants are grown in a controlled environment. Plants grow rapidly in this system.


Hydroponics is an expensive process of growing marijuana. You need to monitor the system regularly and is electricity dependent.
A small mistake could lead to the destruction the whole thing which you have been planning to prepare for ages.

Steps on how to grow weed indoors Hydroponically:

Please make sure to follow every step properly.

The first step is to gather all the important basic items necessary for growing cannabis. These could be seeds or clones (depends on your preference), white color paint, hydroponic nutrients, containers or pots, medium for containers such as coconut coir, fluorescent lighting system, timer, pH detection, etc.

Next step would be to prepare your walls to get a greater yield of weed. Since you are growing indoor, you need to ensure that you provide your crop with an appropriate amount of light. For that, you need to prep your wall by painting them semi-white. Then you have to set up the lights and hang them at the most suitable spot. For the average growth of your plant, you need to provide your plant with about 3000 lumens per square foot. And around 7000 to 10000 lumens per square foot, for much higher yield. Also, keep in mind that your light system should not be a reason for overheating. That could cause an ultimate burn out of a plant. 90 degree Fahrenheit is the maximum temperature that a marijuana plant can bear. You must also ensure that you grow area has a proper ventilation system for your plants as it is an essential requirement for an ideal environment to cultivate crops.
Next step is to select how to grow weed indoors for yourself. You should choose between seeds and cloning. Since seeds need to germinate properly before planting, you need to choose the best seeds and germinate them using the methods I have mentioned in the article before already. Then transfer the germinated seeds to Rockwool block which is important for the initial growth phase of the plants. Then you can start watering your plant and feed with other nutrients in your hydroponic system. The ideal pH level at this stage should be around 5.0 to 6.0. Start giving average amount of nutrients and then keep increasing gradually. Always keep in mind not to overfeed your plants with nutrients as that can be devastating for them. Check and keep adjusting the supply of light according to the requirements of your plants. Too less light or more light could be problematic for your cannabis plant. Same thing goes for proper ventilation; keep monitoring this too.

The next crucial phases are vegetation and flowering. So you need to ensure perfect environmental conditions for the vegetation and flowering of plants. You could also use the height of your plant to determine the growth time for your plants in the vegetative phase. The usual height for a plant to be in a vegetative phase is around 6 to 18’’. This height may double during the stage of flowering; you can then understand that your plant has reached its flowering stage. Since light has a very important role to play in the flowering phase of a plant, make sure that light is being provided to plant for 12 hours a day. Once you are done with setting up the favorable light conditions for your grow garden, you would now be able to determine the sex of the plant. Female plants start growing white hairs whereas you will be able to see small balls on the male ones.
You should now start removing all the male plants now because they will pollinate the females. And pollinated plants will never develop that amazing taste that the non-pollinated plants will. Then comes the stage of the plant growth where you’ll have to wait for it to become mature. Do not lose patience here, as it might take around 6-12 weeks for your cannabis plants to become fully mature.
Before a week of harvesting, supply the plants with water only. Avoid using fewer nutrients at this time, since you may end up feeling the taste of those nutrients while smoking weed. Next step is to check if the hairs of plants have turned out to be brown or not. When you can see that 50 to 75% of the hairs have turned brown, you understand that it’s time to harvest your marijuana.

The importance of light in growing cannabis:

Cannabis plants require ample amount of light to grow. This is one of the most critical factors for the greater yield of weed. Light is also crucial for their maintenance as they won’t be able to sustain if the suitable amount and proper type of lighting are not provided to them. It doesn’t matter where you grow your cannabis – in soil or in a hydroponic system; light is the most wanted nutrient for the healthy growth of the plants.

Light Systems:

There are many options to choose lighting system from to grow weed indoors. Different systems come with their own set of advantages and disadvantages. The various lighting systems could be – bulbs, reflectors, ballast, timer, etc. Any proper lighting system which has the capability to stimulate the hormones of the plants which could aid in the rapid growth of cannabis plants can be result oriented, and you could choose them. Of course, you can select lights based on your budget and your grow area too.

Important Information about the Role of Light (very important to grow weed indoors):

You need to determine the color and temperature of light before choosing a lighting system. Various colors ranges will have various impacts. You can get help from CCT (correlated color temperature) to determine as CCT rating tells the magnitude of the temperature of HID fluorescent lights.

When you do a small research before setting up a lighting system, you will find that different growers are using the maximum 1000 wattage for growing cannabis plants. More than 1000 watt will be harmful to plants, but less than 1000 will be just fine. It’s already mentioned in this post that a marijuana crop needs at least of 3000 lumens per square foot. Lumens is a metric used to determine the light emitted by any light source per square foot. For getting maximum productivity out of cannabis plants, you should supply 7000 to 10,000 lumens per square foot.

Sources of Light

You know that when you grow a plant indoor, there will be no natural light or sun light available for the plants. So you will need some artificial light source to provide to your plants for photosynthesis (the process where plants make food). You can find some useful information regarding that below:

Some LED grow lights for growing weed indoors, and fluorescent lights are perfect for the growth of marijuana plant. They are an excellent source of lighting that cannabis plant requires and are used worldwide by many growers. I have mentioned quite a few times that cannabis sativa needs a good amount of light and you cannot just ignore this requirement if you are a serious grower and want to yield great results. Compact fluorescent light (short named CFL) is also available on the market. The good thing about CFLs is their availability. You can find them almost everywhere. Whereas, you might not find HID lights everywhere.

LED lighting system, at its early times, was underrated and not appreciated. But today, LED lights are highly preferred and bought for growing plants indoors. There are so many benefits that these LED grow lights have. Out of all the advantages that they have, I must mention that the best one is it produces full spectrum light with a very low level of heat.

Placement of Light

The distance of light from plant varies depending on the type of light you are using. In a case of heat emitting grow lights, you should place them a bit farther above the plant. And if the light you use, does not emit too much heat then you can hang it at the height of 10 to 14 inches from the plant.

Lighting Schedules for Different Stages of the growing marijuana plant

Cannabis plants require different schedules and hours of lighting, depending on their phases of growth. At its seedling stage, a Marijuana plant needs 16 to 18 hours of proper lighting. In the vegetative stage, the requirement increases to 18 to 24 hours daily.
In the flowering stage, cannabis plant requires 12 hours of lighting.
Light plays a vital role in the nourishment of marijuana plants. I am sure you want excellent quality weed after all the hard work you are putting in for growing weed indoors. Then please make sure that you supply proper lighting according to the demand of cannabis sativa. If you don’t provide good lighting to grow marijuana, it can cause bad effects on the yield.

Harvesting marijuana:

Here comes the best part. After a long wait of growing marijuana, you finally want to harvest the crop and enjoy the weed. But many growers think that harvesting weed is tough and requires too much effort. It is only a misconception about marijuana that is being spread. Harvesting is a super fun thing to do after putting so much hard work and patience in the growing phases of the plants. Now is the time to learn the most interesting, fun and awesome part of the whole process.

Best time to harvest:

You can determine the right time to harvest marijuana by just looking at the color of the pistils or hairs covering the buds. You will notice that at the beginning they were white, but during the time of harvesting, they turn dark brown. When you see that their color turned into dark brown, you understand that it’s probably the right time to make your harvesting tools ready.

How to Harvest?

Be patient and on the day of harvesting, start off early in the morning. Harvesting is not a difficult thing to do but probably a very time-consuming work. Start by cutting the plant completely from its roots. Do the same thing to all the plants that you grew in your grow area. Best thing would be, to begin with cutting the heavier and larger plants first. After you’re done with cutting, trimming and manicuring are the next steps. When you’re done, you could leave them in a place, where you want the plants to dry. The cheapest, most economical and most reliable way to dry your plants are to leave them in the open air. If you want, you could buy drying machines too; they are also available in the markets these days which help in drying your cannabis quickly and efficiently. But if you could wait this long, I would suggest to go easy on your pocket and let them dry naturally.

What Time of Day to Select for Harvesting?

The night is the best time to harvest. It’s a good idea to harvest in the dark because we all know that the female plants store food which they prepared during the day time via photosynthesis. But hey, wait, this rule applies to those who grew marijuana outside in the open air and sun. Since you are an indoor grower, you need to pick a time as per your plant’s lighting schedule. If you provided light to them in the night hours, then you should harvest the product in the day time. If you provided light to your plants in the day hours, then go for the harvesting in the night. Look at the number of plants that you’ve been growing in your grow area. Then estimate the amount of time that you think you will take in cutting all those plants. That way you can decide when to start harvesting so that you get done by the time you want to get free of this task.

Time to make the weed burnable and tasty

You must already be knowing a primary thing that plants don’t die when you cut them. They only end up dying when their water is dried up. So as a matter of fact, you need to leave them at least for 7 days in a normal temperature of around 70 degrees Fahrenheit and 50 percent humidity to dry the moisture from the plant first. Just be patient here during this process.

After drying, the next step is curing. Curing would take more time if the harvesting were not done properly according to the standards. Professional growers who are aware of the proper ways to harvest marijuana don’t take too many days in curing. Why is curing important? It’s in order to make the herb smooth and flawless to smoke. Mostly, the buds are cured within 2 weeks after drying. The maximum time they can take to cure is around 14 to 16 days.

At this period, don’t be in a rush and let the buds cure for a long time. It’s understandable that you might grow impatient. But it’s okay because you are a new, inexperienced grower, so you might not know what a little mistake can cost you. If you don’t let the buds cure, you will get less effective and low-quality yield which you would not like after putting so much hard work, time and money.
Curing is a necessary process for the evenness of the moisture in any herb. So is the case with marijuana; to make the drying process even and slower, we need to give the plants time to get cured.

Some facts about curing and drying

THC is the element present in fresh marijuana which turns into psychoactive items that make you a high after smoking it. Dried and cured weed are always much more flavorful, tastier and much more efficient than that of the fresh ones. Buds go to frail when they are dried too fast. So make sure not to increase the level of humidity. Set the humidity between 45% – 55% to attain the better results.
Air circulation is also very critical during curing; so you might need to open the bins for at least 10 minutes every 4 hours.

I have bought many guide books on growing marijuana indoors and have been following them. But they were not very helpful regarding understanding properly especially for new growers who want to get started with growing weed indoors for the first time or are looking and researching on ‘how to grow weed indoors.’ And those books are very lengthy and time-consuming. That’s why I wanted to write a post on how to grow weed indoors and I did it. It took me long to finish writing this article. And I included much information from those books as well but in simple language so that it’s understandable by every marijuana lovers. I hope you liked this post and I look forward to receiving your feedback on the efforts that I made and if this post is helpful for you or not.

I wish you all the best in growing your stuff! Feel free to browse through my other posts for more information.

Reviews for Top rated LED Grow Lights of 2017

Since you’re here in this site, I am assuming you are looking for a new LED grow light for your grow room. Since it’s a big investment, I’ve hand-picked the best lights in the market. I came up with this table after a lot of research – asked friends, reached out to people online, read up many reviews and then came up with these suggestions below.

You’ll need to consider a few factors to choose the best light for your growing room. The light that you would buy need to be powerful enough to cover the area where you grow your weed at. That might also differ depending on whether you have a separate and dedicated space for seedlings & clones or if your weed fully in one place.

The second factor is if you want an all-purpose light, or if you simply plan to supplement your weed with other lamps used for vegetation and flowering or home gardening.

The good thing about LED lights is that you don’t have to worry about replacing bulbs frequently, having to deal with ballast, or running too hot. You wouldn’t find these issues with LEDs. Such issues used to be with HID HPS lights.

Now, how do we choose the best lights for growing cannabis? Let’s take a close look at the best LED grow lights arranged by the area that they cover. That will help you match and pick a light according to the size of your grow space.

Mentioned below are some of the most important things to consider when choosing to buy an LED grow light:


As mentioned above at the beginning of my post, you should always keep in mind the area that the light needs to cover for growing your weed. That will help you in determining the number of LED lights that you would be needing and which type of LEDs would provide you the best coverage. You can place more lights adjacent to each other to cover more space.


You can go for a full-spectrum LED grow light to assist in all growth phases.


You must also look for the angle of dispersion within the LED bulbs. The greater the angles, the more the coverage, while the lesser angles, the lesser the dispersion and more direct light. You need to select between these two options according to your needs.


You need to figure out the features that are important to you and the amount of money you are ready to spend. I would say if you can invest better, you can grow better weed. But as always, you need to consider the factors, and you can decide that based on how you plan to grow your plant.


Well, the answer is simple. Full spectrum LED grow lights are a comparatively new product in the market. And that’s the reason why many growers are not that familiar with these new lights. While most of the growers might believe that large fluorescent lights are the best grow lights to use for an indoor growing marijuana garden, they simply aren’t. I wouldn’t say that they are bad. They are good, but Full spectrum light systems are better because they imitate sunlight. LEDs are environment-friendly too – plus point!

  1. They stimulate high yields
  2. They definitely cost less to run over time
  3. They don’t heat up. Instead, they run cool and hence don’t need extra fans
  4. They don’t have the problem of flickering
  5. They don’t need ballast for supporting
  6. Their lamps don’t need to be replaced for 50,000 hours or more—that saves you years of hassle and provides a problem-free service.
So, you might want to keep it in your agenda to consider updating an outdated system to a full-spectrum LED panel now.

  7. Sunglasses: Shades? For growing cannabis? Yes, that’s right. Sunglasses. You wear them outside too, right, to protect your eyes from UV rays. Similarly, you need to protect your eyes from UV rays indoors too when you’re running a full-spectrum LED light and have to look at it often.

Nutrients: Like every other organism, even plants need their nutrients and minerals. The nutrients that you provide them don’t just affect the yield. They also affect the flavour. Therefore, always choose your plants’ nutrients cleverly.

Grow tent: Tents provide you with a better ability to control the climate for your weed. It’s a good idea to get a tent even if you’re already growing in a closet or an enclosed space. A tent can help you protect your cannabis from stray light sources when they are supposed to be kept in the dark. Plus, it keeps humidity and smells under control too.

Light meter: You might think that only advanced growers use them. But that’s not the case. You can use one, too. Then when you’re advanced grower, you’ll already know how to use them. Always better to use such stuff even when you’re just beginning.

Thermometer and hygrometer: You will definitely want to know the ambient conditions inside your grow tent. For you, we have picked the most excellent model in the market that will last for years.

Now coming back to the main point of the article, what are the Best LED Grow Lights for the Money. We sorted our list of LED grow lights based on the results they showed and the features they offer.

Advanced Platinum Series P900

To keep your grow room/tent and plants cool, all of the Advanced Platinum Series light models from PlatinumLED grow lights use groundbreaking full-spectrum technology. At the same time, they keep meeting your plants’ all light needs. The P900 provide their trademark “2x-3x intensity” lights that offer two to three times the brightness of competing LED grow lights.

The P900 has 12 bands of wavelengths of light which include both infrared (IR) and ultraviolet (UV), the fragments of light you cannot see with the naked eye. This panel, and others like it in the Advanced Platinum lineup, is about as close to sunlight as you can get indoors. This model is useful for every phase of growing cannabis and you’ll love it.

You can keep it less bright for sprouting by turning the “Veg” switch on or increase the intensity of the light by flipping the “Bloom” switch on. The 90-degree angle of the LED focusing lenses are designed to send light down into the canopy of your plants which helps in tremendous growth.

It is also energy efficient. It can replace a 1000-watt HPS light at a full intensity and still use only 515 watts of electricity. The price of electricity in the US is around 12 cents per kilowatt-hour (average) and using a 1000-watt HPS light costs you 12 cents every hour. But using the P900 gives the same or better quality of light and intensity at half the price of a 1000 watt HPS.

The P900, when suspended at 18-inches above the plants in your garden, its core coverage reaches up to 3 by 5 feet. The maximum coverage that it can provide is 4 by 6 feet. These dimensions are critical to keep in mind because at different stages of growth of cannabis, you’ll be adjusting (raising or lowering) the light according to your plants’ requirements. During the stage of sprouting, you can cover up to 4 by 6 feet. But at more vigorous stages like flowering, you’ll cover lesser area because you will need more concentrated light. An adult cannabis usually takes up at least a square foot of space in a 3-gallon flower pot, so the P900 model can flower between 12 to 24 at a time.

This light system is not budget friendly. But the fact that the P1200 LED drivers work anywhere in the world makes it worth it. They accept 110V or 220V input (or correctly, 85V to 260V). PlatinumLED offers one of the better warranties in the market. They come with a 90-day money-back guarantee and 5-year complete warranty.

Advanced Platinum Series P600

Consider the Advanced Platinum Series P600 as the most advanced grow light people have ever used. This grow light could be a heavy investment, but most of the growers will swear by the premium results that these lights give which are worth a hefty price tag. It has a durable build and is easy to set up. If you have enough money to invest in your crops, I suggest you go for it because it’s one of the best LED grow lights to buy for growing your cannabis. The core coverage area that this light offers is about 2 feet by 5 feet, so you can flip the “Bloom” switch on for about 5 to 10 plants, max.

The Advanced Platinum Series combined intense light and powerful fans in such a way that the light is intense enough that you can see it penetrate the plants and the same time doesn’t burn your plants up – an excellent feature. These lights also come with a 5-year warranty and awesome customer service provided by the company directly. Imagine the energy that you can save against an 800W HPS alone, this unit will pay for itself before the warranty runs out.

Advanced Platinum Series P300 – Perfect for small grow tents (3′ by 2′)

The Advanced Platinum Series P300 is a great runner-up to the P600. This is a more affordable LED grow light at around half the price of the P600 and offers quite a number of the same benefits as the P600. For those who love the P600 but don’t have quite that large of a budget or size of a grow tent, they can surely go for this model.

It is perfect for compact grow areas with a coverage of about 4.5 feet by 3.8 feet at an 18-inch height. You can also use these lights along with additional lamps for larger areas. It’s an excellent energy efficient alternative to a traditional light as it uses only 180 watts of power. This light is perfect for small home growers. Just as the P600 represents the higher end of the market, this is still a significant piece of equipment, basically a steal for the astonishing coverage it gives.

This system has a considerably high PAR (photosynthetically active radiation) per lumen output compared to any other LED grow light panel we’ve seen. That means the panel gives out about two to three times the intensity of other grow lights.

The most important thing about this light system is that it has an 11 band spectrum that gives your marijuana (cannabis) plants the nourishment value including those needed from UV (ultraviolet) and IR (infrared). They use 3W LEDs in all their light chips. The best 3-watt panels have an additional lens to focus the light a bit more. This model comes with a primary 60-degree lens and a secondary 90-degree focusing lens to give more intensity for enhancing plat growth.

Another reason for the moderately higher price tag is because the chips in this lamp are also replaceable. This feature allows you to keep that 400-watt output, even when a chip blows. You can just order one chip from the manufacturer and replace it when it arrives. PlatinumLED comes with a 5-year guarantee thereby offering security to their customers.

California Lightworks 440W LED Grow Light (ideally for a 3′ by 3′ grow tent)

Buy from

This model uses 5W LEDs – 88 of them. Therefore, the light is a bit more intense than those with 3W chips.  The optics are all high quality jewel glass focused at an angle of 90 degrees. Plus, it has two 15W UV-B tubes to enhance the growth of plants/cannabis at the flowering stages. The model runs cool and quiet with its built-in fans. Also, it comes with a 3-year warranty.

MarsHydro Reflector 410 Watt LED Grow Light

The MarsHydro Reflector is a better choice for small square 4’ by 4’ grow tents than many of the rectangular panels that we’ve reviewed. There was slight singing when the “flower” setting was used. But we could see no such issues with the “veg” setting – one of the advantages of an adjustable spectrum. Those who are considering buying other lights will probably want to use this one as a backup light, but it undoubtedly excels when compared to less expensive options.

In fact, this is one of my favorite lamp that I like to use for my marijuana seedlings because it covers four critical wavelengths of the spectrum.

This lamp may look small, but it has an impressive life span of over 50,000 hours which is somewhat unusual for an inexpensively priced lamp. Also, it comes with a 2-year warranty. The light will work with the full cycle of growth including the flowering stage, but you might want to add an additional lamp for that part.

LED Grow Lights FAQs:

If you’re a beginner in growing cannabis or just want to improvise on existing knowledge, enjoy the read!

What is an LED Grow Light?

LED stands for ‘light emitting diode.’ It helps plants grow best when you plant indoors. It provides light energy that mimics the sunlight and affects these plants the same way sunlight does when plants are grown outdoors. It is environment/eco-friendly, user-friendly and provides various wavelengths of visible and invisible light including UV and IR rays that can directly enhance the growth and the yield of any plant grown under these lights.

How Do LED Grow Lights Work?

How can these tiny little lights mimic sunlight and help your plants grow better?

Plants usually tend to absorb more blue light than other colors like white or green light; hence, UV (ultraviolet) rays are the best to generate robust plant growth. While on the other hand, IR (infrared rays) act as the best catalysts for germination and blooming boost.

You can adjust the wavelengths according to the requirements of your plants’ growth conditions in the grow tent or area. To help stimulate the growth of plants in their vegetative phase, you can use UV rays to increase the cell division when the plants absorb the rays. The plants then grow quickly and result in more yield due to the increase in cell division.

If you want to treat your plant during the flowering stage, you can opt for the LED lights which provide IR (infrared) rays. The buds and apex of the plant absorb these promptly and this, in turn, helps them bloom quickly and heavily.

A LED grow light that has a wide range of wavelength options is always the best choice to buy so that you can adjust according to the effects that you need in your grow room. Various factors such as the amount of light output, type of light emitted (UV/IR), types of plants you want to grow, wavelength, Lumen per area, the height between plants and light etc., affect the growth and yield of the plant that you are growing.

Advantages of using LED Grow Lights:

Before the advent of LED grow lights, there were other methods in use like high-pressure sodium lamps, fluorescent bulbs, etc. But these methods were not good for small grow room owners who needed to have a small, tight or compact structure. The reason is these lights would occupy a lot of space due to the setup of all the equipment necessary to deal with the production of the huge amount of heat. They also needed to have a proper ventilation system to avoid building up of heat. These things made the process very hard for small grow owners who would have to invest a lot to grow their plants.

On the other hand, LED lights take up very less space, they don’t need their bulbs to be replaced, they don’t need ballasts to be managed, are eco-friendly, they don’t contribute extra heat and use half the electricity to run or sometimes even less than half the electricity to operate. They are very compact and easy to install too. You don’t need to have any specific knowledge to install these lights. You just need a proper place so that you can hang them above the plants in your grow garden at the required distance. They don’t need separate ventilation to be set up. They can work without any huge ventilation or large fan types.

They can also be installed adjacent to each other in order to give more coverage, thanks to their compact design.

The variety and control that they can provide are just awesome. You can adjust their wavelengths easily and can also change the modes for vegetative and bloom depending on the phases of your plants’ growth.

These factors combined with the great results that they give with a lot less hassle and price, have made us huge fans.

How Many Watts Do You Need for growing your plants?

First, you will need to find the area and the number of plants that you need to cover. Then you can figure out the exact wattage that you should have in your grow area

If you have 1 square foot of area that has one plant potted in it, then, the recommended wattage is 25 watts per square foot. If you have two plants in one sq. ft., then the recommended wattage would be 50 watts per Sq. Ft. and so on. So, if you consider an example of an LED grow light having a total wattage of 250 watts, you could grow 8-10 plants under it.
