6 autoflowers in a 2×4 tent? Too much?
- Date of joining:June 17, 2017 Messages:235 Likes Received:80 Hello everyone, I hope you are all doing well and enjoying your new growth. Im on day 6 of seedling with six Dinafem autoflowers, five OG Kush plants, and one XXL Amnesia plant. I’m using 18L pots
- I’m not sure how many gallon that is in the UK, but it’s probably 3 or 5. Anyway, I have them in a 2×4 configuration. This mars hydro tent is around 6ft 5 in height, based on my estimation. The question is, will they be able to bloom out in this tent? This is my first time running with autos and just my second time running. It might be possible to fit two more automobiles in the same size pots in the tent’s footprint, but there would be no ground room left over for movement. Is it best to keep them at 6 for this particular tent? Is this a disproportionate number of automatics for a 2×4? Should I start two more to make up the difference? I have two mars hydro 600 tents, and while I could purchase another tent in an emergency and operate four plants with one light in each, I want to make the most of my tents’ space and other resources. Thank you in advance for any comments or recommendations you may have

Personally, I would not put six automobiles in an 8 sq ft pot of that size, but I would be very content with three vehicles in that space. I’ve had tight tents in the past, and I could feel it whenever I took the plants out of the tent or while I was watering them. In that particular grow, I had three autoflowers and one picture, all of which were grown in 5 gallon pots in a 4’x4′ tent.
Right now, I only have two images in a 2’x4′ tent, which is more than plenty.
I had one auto running on my balcony outside, so I LST’d the living daylights out of it to keep the noise down.

If you’ve been looking into this subject for a time, you’ve most likely come across 10 different solutions for each tent size you’re considering. There is a valid explanation for this. Cannabis plants can grow to be enormous in size, depending on the strain, the size of the pot, the growth method, and other factors. The good news is that you have complete control over all of this, and as a result, you have complete control over the growth of your plants. The primary technique by which you do this is through the developing approach you employ.
In case you’re unfamiliar with any of the methods covered, we’ll provide a brief overview of each one, along with the advantages and disadvantages of each one.
How Many Plants Can I Fit In A 2 x 2 Grow Tent?
In a 2 by 2 tent, the majority of individuals will grow a single plant. Use strategies like as low stress training andlollipopping or other sorts of trimming to ensure that your plant fills out the area with the greatest amount of colas possible in a 3 gallon or 5 gallon container. The Sea of Green technique (abbreviated SOG) is another option for growing a high number of tiny plants in a limited amount of space. You will be able to fit four, or possibly more, plants into this area if you do this.
While I understand that there are smaller grow tents available than a 2 by 2 foot space, this is the least size we want to explore for the sake of this article.
They are intended for specialized purposes like as sowing or cloning, with some of the somewhat bigger ones being intended for vegging.
How Many Plants Can You Fit In A 2 x 4 Grow Tent?
Considering that this tent is precisely twice the size of the previous one, you’re most likely imagining that you’ll be able to fit twice as many plants inside it, providing they’re all the same size.
And you’re absolutely correct. Small plants may be accommodated in a 2 x 4 foot grow tent, and you can fit as many as eight of them in there. In a 2 by 4 foot space, you can obtain two plants if you let them grow to their “natural” size.
How Many Plants Fit In A 3 x 3 Grow Tent?
When you get to the 3 by 3 size, things start to become interesting. You find yourself with a plethora of possibilities. You could put four plants in this size tent, but you’d have to keep them on the tiny side in order to make them work. You could use the SOG approach to cram even more plants into the space available. You have the potential to grow nine or perhaps more. Alternatively, you may travel the opposite way. You could cultivate a single plant if you wanted to. It goes without saying that you must prevent it from growing too tall, as grow tents have a maximum height restriction.
How Many Plants Can I Fit In A 4 x 4 Grow Tent?
This is the most typical tent size for a home grow, probably because it is ideal for using a 1000 watt HID lamp or a similar LED grow light to illuminate the plant. It’s also small enough to fit comfortably in the majority of households. As with the 33%, there is a great deal of possibility for customization. With SOG, you may produce one enormous (meaning wide, but not extremely tall) plant, four “regular-sized” plants, or as many as 16 or more.
How Many Plants Can You Fit In A 5 x 5 Grow Tent?
For a 1000-watt equivalent grow light, a 55 grow tent is also an excellent choice. The finest LED fixtures have a five-by-five-foot footprint. In a 5 by 5 area, you can grow up to 25 plants using SOG techniques. If you like to let your plants develop to their full potential, one of these tents might accommodate four reasonably large marijuana plants. Some cultivate a single massive plant in a 55 container.
How Many Plants Fit In A 4 x 8 Grow Tent?
Because a 4 by 8 foot grow tent is precisely twice as large as a 4 by 4, you can fit twice as many plants inside as you can in a 4 by 4. The Spider Farmer 4000 has two 1000 watt equivalent lights, which allows you to effortlessly grow two giant plants, eight good-sized plants, or as many as 32 or more little plants in a sea of green growth.
How Many Plants Can I Fit In A 10 x 10 Grow Tent?
Last but not least, we have the enormous 10 by 10 foot tent. It has four times the floor space of a 5 by 5, which means you can grow four times the number of plants in it. You should, however, ensure that there is enough space in there for you to be able to access all of the plants comfortably. However, you may do this by just making them a little smaller. It is possible to cultivate 100 or more little plants (though you may wish to lower this number somewhat to allow yourself enough space to reach every plant), 25 good-sized marijuana plants, or four enormous cannabis plants in this manner.
What Size Plants Should You Grow?
The amount of marijuana plants that may be accommodated in any given tent size is totally dependent on the size of the plants.
Moreover, it is something over which you have some control. Many little plants are preferred by certain growers, whereas few huge plants are preferred by others. There are pros and downsides to both growth strategies, depending on your perspective. Let’s take a closer look at each of them.
Many Small Plants (Sea Of Green)
Using the Sea of Green technique, you may grow a large number of plants in a short amount of space, allowing you to accommodate more plants in your grow area. The end product appears to be a sea of green. This is perhaps the quickest and most straightforward technique of growing, which explains why it is so often used. You begin blooming the plants as soon as possible in order to prevent them from growing into huge plants. A consequence of this is that each plant typically only has one bud location.
The buds, on the other hand, are much smaller than those on a bigger plant.
Advantages
- More harvests each year are possible because of the shorter growing cycle. There is no (or very little) pruning or trimming required. Because it does not require much vertical space, it is cost effective. It does not need a lot of soil (or other media)
Disadvantages
- Colas are smaller than in other ways (but there are more harvests)
- Some countries set restrictions on the number of plants that can be lawfully grown
- Others do not. There are more plants to water and feed with nutrients.
One Huge Plant
The amount of time spent watering and feeding nutrients is reduced if you simply have a single plant to take care of. You will, however, have to put in a lot of stress training, pruning, and cutting to get the results you want. You’ll want to educate your plant to grow horizontally, rather than vertically, so that it spreads out more sideways than it does up. Allow it to grow vertically from there until it has spread out to the side sufficiently to fill the growing area available. As a consequence, you will have the greatest number of bud sites to fill your available space, which equals a larger yield.
- Depending on the size of the object, that is.
- You’ll want to trim and maybe lollipop your plant in order to guarantee that as many bud sites as possible are exposed to light and that the plant focuses all of its efforts to producing those bud sites and nothing else throughout the growing season.
- Once the branches begin to grow vertically, growers use a net or a trellis to hold them in place until they are ready to harvest.
- Furthermore, development behind the net is eliminated since it does not receive much light in the first place.
Advantages
- If the number of plants allowed is restricted by regulation, this is an excellent method of increasing yields. It takes far less work to water and feed a single plant. Larger buds, which are typically more powerful.
Disadvantages
- Because of the longer growing cycle, there are more harvests every year. Stress training, trimming, and pruning are all required. There is a greater requirement for vertical space, however this may be mitigated by utilizing a technology such as SCROG
- More soil or other material is required, as well as larger pots.
Several Medium to Large Plants
Finally, you have the option of growing to whatever size in between. There truly isn’t a limit to what can be done here. If you’re searching for an average-sized marijuana plant, you can expect it to grow to be about 4 square feet in size, which corresponds to an area of approximately 2 by 2 feet. Ideally, you’ll want to maintain these plants in a 3 or 5 gallon pot and train them to a certain degree. A SCROG grow is a good choice for plants of this size since it maximizes production. Several times over-top the plants to increase the amount of colas while keeping the overall height under control.
At the end of the day, any one of these strategies can be effective, and the choice ultimately comes down to personal preference. Additional considerations should be made while determining the size of your tent and the quantity of plants that will be placed inside of it.
Other Things to Consider
In addition to what we’ve already discussed, make sure you have enough space in the tent to be able to access to every plant and water it or provide whatever other care may be required. When working in bigger tents, this is especially crucial because plants at the back may be difficult to reach. You’ll also want to make sure there’s adequate room for any equipment you might require. This might include grow lights, filters, fans, humidifiers to enhance relative humidity, dehumidifiers to decrease relative humidity, air conditioning or heating, among other things.
- Just make sure that there is enough space in the tent for everything you need to bring with you.
- This term refers to the sucking inward of the tent walls as a result of the negative pressure created by your ventilation system within the tent.
- Keep in mind that tent suck should be taken into consideration while determining how many plants to place in the tent.
- As an alternative, you may take steps to prevent tent suck, such as installing support beams to keep the canvas walls in place and prevent them from sucking inward.
How Many Plants In A Grow Tent: Final Thoughts
The most important message from this is that it is difficult to provide a response to the issue of how many plants can be accommodated in a certain size grow tent. You would need to know the size of the plants before you could proceed. And that is something over which you, as a farmer, have complete command and responsibility. As a result, the first decision you will need to make will be how big you want your plants to grow. That information will allow you to determine how many of them you can put into your grow tent, or how large of a grow tent you will need to be capable of growing any number of plants in one area of your garden.

There are various factors that influence the growth of an autoflower, including genetics, lighting, and pot size. It is possible to grow up to six plants per square meter of growing space. Almost of cannabis consumers who wish to begin growing their own cannabis have a desire to be able to meet their demands without having to pay excessive amounts of money. In order to accomplish this, you must maximize the use of your growing space.
Learn all you need to know about the amount of room Autoflowering Cannabis need to mature properly. There are a lot of things that can assist you in accomplishing this without having to invest more funds on another grow setup.
1. What Determines Plant Size In Nature?
When a plant is growing in the wild, there is nothing to prevent it from developing to its full potential. Because they are not developing in a controlled environment, cannabis plants cultivated outdoors can grow to be more than 3 meters tall. That, of course, does not apply to those who cultivate their plants inside. Indoor growers have a limited quantity of resources, including room, lighting, fertilizers, and growing material. This may appear to be a negative development, but it also provides us with the capacity to exert total control over our plant, including the ability to select how tall, bushy, and even how many buds it will generate.
2. What Determines Plant Size Indoors?
The size of our plant will be determined by a number of criteria, the most important of which are: All of them may be customized to meet your needs, and they can be tailored to your grow area and the genetics you’re using to determine how much cannabis can be produced per square meter of space.
Genetics
For those who are unfamiliar with the terminology, Sativas grow tall and thin whereas Indicas grow short and bushy. This is one of the most important aspects that will influence the growth of your plant. Despite the fact that it is difficult to find pure Sativa or Indica genetics nowadays, the hybrids that most growers cultivate are a cross between pure Indica and Sativa genetics, and depending on the hybrid (it can be Sativa or Indica-dominant), it will grow shorter or taller depending on the genetics.
- This strain was grown in conjunction with other quick buds strains.
- In 19L pots, I use soil and operate on a 20/4 light cycle.
- fastman.
- As a result, if you’re seeking to produce Sativa-dominant strains, you won’t be able to fit as much into your grow tent as you would if you were growing Indica-dominant strains of marijuana.
Pot Size
Another extremely essential issue is the size of the pot. The quantity of root growth under the surface of the soil will directly affect the size of your plant; for example, if you grow in a 5 L pot, your plant will be smaller than if you grow in a 10 L pot. Even if there is a difference in size between Sativa-dominant and Indica-dominant strains, growing them in a small pot will reduce their total size since they will not have enough area for the roots to grow. Keep in mind that the amount of your yield is determined by the size of the pot you use.
Typically, an autoflower grown in an 11 L pot will reach its full height, but an autoflower grown in a 5 L pot will reach a medium height and an autoflower grown in a 3 L would reach a modest height.
If you don’t have a problem with limited space, we recommend using 11-12 L pots to allow your plants to grow to their maximum potential.
Lights
The amount and intensity of light will also have an impact on not only the size of the buds, but also the amount of resin and the density of the buds. When you grow too many plants in a limited space, some of them may shadow out the others, preventing the ones left below from developing correctly. That is why you must first determine the size of your grow space before purchasing grow lights; this will guarantee that you receive adequate coverage to meet the needs of your whole cannabis crop.
Training
There are several plant training strategies available, and while the methods differ, all of them have the same goal: to adapt your plant to the environment in which it will be grown. We advocate employing low stress training (LST) techniques or the Sea of Green (SOG) approach for autoflowers in order to get the most out of your grow space.
3. How To Calculate The Area Of My Growing Space
Even if the methods used to train plants differ, all of them have the same goal: to help your plant get more acclimated to its new environment. In order to get the most out of your grow room, we recommend employing low stress training (LST) techniques or the Sea of Green (SOG) approach for autoflowers.
4. Calculate Number Of Plants Based On Pot Size
For the sake of these examples, we will assume a 1 square meter space, but you may apply the same arithmetic to calculate the same results using the measurements of your own space. Making an accurate calculation of the precise number of plants that we can fit in our area or the exact number of square meters per autoflower that you require might be challenging; the following is a basic guideline that may vary based on your growing environment. Different shapes and sizes of pots are available, so depending on the size of your grow area, you will be able to accommodate many of them.
Typically, we follow the guidelines in the following table:
| Pot Size | Number Of Plants Per m 2 | Plant Size |
|---|---|---|
| 3 L (0.6 gal) | 25 | 25 cm (9.8 in) |
| 5 L (1.3 gal) | 18 | 60 cm (23.6 in) |
| 11 L (2.9 gal) | 9 | Full plant height |
| 15 L (3.9 gal) | 5 | Full plant height |
| 18 L (4.7 gal) | 2 | Full plant height |
| 21 L (5.5 gal) | 1 | Full plant height |
It is possible to compute the number of plants by multiplying the number of plants by the size of our growing space. Consider the following scenario: our growing space is 2 m (6.5 ft) wide and 3 m (9.8 ft) long. Because (2 x 3 = 6) the size of our growing space equals 6 square meter (6.5 ft2) (64.5 ft 2). How to calculate the number of plants you’ll need based on the size of your container. Using the table as our guide, 5 plants in 15 L pots may be accommodated in 1 m 2, therefore we multiply the number of plants by the size of the pots: 5 plants multiplied by 6 square meters equals 30 plants.
You can change this to fit any size area simply by glancing at the table and performing some basic arithmetic calculations.
Use rectangular pots if you want to maximize the amount of cannabis you can put into your grow space. This will prevent you from wasting valuable growing area. Use the same reasoning to get the number of plants per square foot of space.
5. Calculate Light Potency Based On The Number Of Plants
A light fixture can be made up of two sorts of components: light bulbs and LEDs.
LEDs
Because the quality of the individual LEDs varies from one manufacturer to another, it is difficult to calculate using LEDs. The best course of action is to follow the manufacturer’s instructions, which should be included in the light fixture’s instruction manual; if not, we recommend writing them an email and asking for the information. If you have exhausted all possibilities and are still unable to locate the information you want, you can follow the basic rule: A 250-watt LED is equivalent to a 400-watt incandescent bulb.
Despite the fact that each LED is unique, it is possible to utilize this guidance for LEDs by dividing the number of watts by 1.6, which is not suggested because each LED has its own characteristics.
Light Bulbs
Now, with light bulbs, things are a little different, and there is a technique to determine the wattage you will require for your plants; this way, you are not calculating how many square meters per autoflower you will require, but how much light you will require instead. Let’s stick with the example we were working with before this one. Considering we have a space of 6 square meters (64.5 square feet) and already know we can place 30 plants in it, what is the recommended wattage for our setup?
A typical plant requires around 75 W, thus by using the chart below, we can determine how many watts we would require for 30 plants in an area measuring six square meters (sixty-five feet two inches).
| Wattage | Number Of Plants |
|---|---|
| 150 W | 2 |
| 250 W | 3 big or 4 small |
| 400 W | 5 |
| 600 W | 8 |
| 1000 W | 13 big or 14 small |
If you’re cultivating less than 14 plants, you may simply go to the table for the appropriate number. The amount of plants you have to cultivate must be multiplied by 75 W if you’re growing more like in the preceding illustration. As a result, in our case, 30 x 75 w = 2250 W would be required. This suggests that we would require 2250 W to grow 30 plants in 15 L pots in a growing space of 6 square meters (64.5 square feet).
6. How Can Plant Training Help Me In These Situations?
Despite the fact that there are several plant training strategies available, only a handful of them are suitable for use on autoflowers without causing any issues. They are theTie-Down technique and the Sea of Green approach, respectively.
The Tie-Down Method
With this approach, you will aid in the opening up of the branches, allowing light to get deeper into the plant, resulting in additional bud sites and denser buds. You will be able to fit less plants into your grow space while still getting a higher yield as a result of this method. Continuing our example, if we had a growing space of 6 square meters (64.5 square feet), we would be able to accommodate 30 plants.
If you used this strategy, that number would be reduced to around 15 plants, depending on the size of the container. For a general guidance, you might refer to the following table:
| Pot Size | Plant Number Per m 2 |
|---|---|
| 3 L (0.6 gal) | 9 |
| 5 L (1.3 gal) | 6 |
| 11 L (2.9 gal) | 3 |
| 15 L (3.9 gal) | 2 |
We were using 15 L pots in our example, therefore according to the chart, we need to multiply the area by the number of plants, which would be 6 x 2 = 12 in our case. The tie-down approach allows us to squeeze 12 plants into a 6 square meter (64.5 square foot) space, which is equivalent to a total of 64.5 square feet. In order to compute the wattage required for those 12 plants, we must multiply the number of plants by 75 W, resulting in 12 x 75 W = 900 watts of electricity. The number of plants per 6 square meter will be reduced to around 15 plants using the tie-down method, depending on the pot size.
This will not harm your cannabis plants, and in fact, it will encourage them to grow even more aggressively.
Sea Of Green (SOG)
When growing in a Sea of Green, the number of plants produced is greater than when using the Tie-Downmethod and also greater than when growing the plant without any form of training. This is due to the fact that plant training methods are designed to manage the growth of a plant while still yielding as much as feasible. Slowly training your cannabis into a uniform canopy will let light to reach all of the bud sites in an equal amount of time. In general, the following is a good starting point, and as previously said, you can have more or less plants based on your abilities and need.
| Pot Size | Plant Number Per m 2 |
|---|---|
| 3 L (0.6 gal) | 16 |
| 5 L (1.3 gal) | 11 |
| 11 L (2.9 gal) | 8 |
| 15 L (3.9 gal) | 6 |
Just so you’re up to date, we had an area of 6 sq m (64.5 sq ft 2) where we could accommodate 30 plants (without training) in 15 L pots, each of which would use 2250 watts of electricity. For the sake of this example, we are growing in 15 L pots, thus to determine how many plants we can put into a 6 square meter area of SOG, we must multiply the area size by the number of plants per square meter in 15 L pots, which results in 6×6 = 36 plants in our case. What is the formula for calculating light potency for the Sea of Green growth method?
7. In Conclusion
While the square meter per autoflower will vary depending on numerous factors, there is no set number of plants that may be grown in a grow tent of any size, regardless of its size. A combination of your budget, genetics, equipment, and environment will truly define that; so if you were wondering how many autoflowers per square meter to grow or how much an autoflower can yield per square meter, it can be quite complicated; however, doing the math will give you an idea of what you should expect.
- For example, depending on the plant training procedures you use, you may be able to fit more (or fewer) autos per square meter.
- As you complete each grow cycle, you’ll have a better understanding of not only how that specific strain grows, but also of what it requires and what you must provide in order for it to thrive.
- For example, even if you are growing the same strain outdoors and indoors, the results will be slightly (or completely) different growth, which will be visible in how much your plants stretch, yields, aromas, and effect.
- In the event that you are seeking for plants to grow in smaller pots and haven’t selected what to grow in your next cycle yet, we propose ourZkittlez Auto andGorilla Cookies autoflowers.
- I harvested 134g from this gal, which was grown in a 3 gal pot with 24 hours of light.
- It has a diesel-like smell to it.
- Charney.
- The Orange Sherbet Auto and the Wedding Cheesecake Auto are excellent choices if you want to grow fewer plants but bigger.
- And keep in mind that taking proper care of your cannabis will result in gorgeous frosty blooms, regardless of how large or tiny they are.
- Keep in mind that this is only a guide, so there may be slight variations in the plants you can fit and the amount of light your cannabis requires according to the elements mentioned throughout the guide.
This advice will assist newbie growers in figuring things out, but ultimately it comes down to personal choice. The most recent change to this post was made on May 25, 2021.
The Best Grow Lights For A 2×4 Grow Tent – Pictures, Specs, And More
What are the finest grow light options for a 2×4 grow tent and how do you choose them? Take a look at one of the following alternatives: A 150-watt high-pressure sodium (HPS) grow light, a Spider Farmer SF-2000, a Green Sunshine ES300, or the HLG 320-watt DIY quantum board LED grow light are all good options. When selecting a grow light for a 2×4 foot grow tent, the light intensity and consistent coverage area of the lamps are the most significant elements to consider, according to the manufacturer.
All of the alternatives I’ve listed below fulfill or surpass those standards.
Despite the fact that there are a plethora of perplexing lighting options available, either of these grow lights will function well in your 2×4 grow tent.
Many folks who are contemplating 2×4 foot grow tents are also considering 3×3 foot grow tents, according to my observations.
Budget Choice:Hydroplanet 150 watt HPS grow light
Why am I proposing an HPS grow lamp as one among your two-by-four-foot grow tent’s lighting options? I communicate to farmers on a regular basis, and some of them are on a tight budget. For a variety of reasons, this 150 watt high pressure sodium grow lamp from Hydroplanet is an excellent choice for a 2×4 grow tent:
- It is inexpensive. The light intensity is sufficient for two 4x4ft grow tents to be set up. Despite the fact that HPS grow lights have a bad reputation for being heat generators and electricity hogs, this little 150 watt type does not generate much heat and does not waste much electricity due to its modest size. Indeed, it consumes less energy than the LED lights that I’ll be describing later.
Using low-quality lighting is not my first option, and I strongly advise against doing so. In contrast, if you’re really short for cash, the 150 watts of power from this lamp will suffice. One thing I’d recommend to consumers of this Hydroplanet 150w HPS grow light is that they acquire a wing reflector separately rather than utilizing the hood type reflector that comes with the light. Using a wing-style reflector will allow you to distribute light more evenly across your 2×4 foot grow tent. The rest of the time, this grow light is a plug-and-play device.
Simply suspend this light between 18 and 24 inches above your canopy and you’ll be ready to go.

The Spider Farmer SF-2000 is a quantum board LED grow light that is both contemporary and efficient. This light has a coverage area of 2×4 feet and utilizes the same LEDs and driver as the HLG, although it’s priced a little less expensive than the latter. LM301B LEDs were used in this project, and the driver was provided by Mean Well, which is a high quality, industry standard driver. My 2×4 grow tent at home has one, and it looks and functions great. I highly recommend it. You can read the rest of my Spider Farmer review right here.
Take a look at the amount of light that the SF-2000 produces: The SF-2000 emits a spectrum that includes warm white (3000K), cool white (5000K), 660nm (red), and 760nm (blue) wavelengths (infrared).
See what people have produced under Spider Farmer grow lights in the following examples: These photos were taken from Instagram, and you can see the huge buds that the Spider Farmer proprietors have developed. These plants are nothing to be squeamished about.
SF-2000 Key Specifications:
- Will blossom in a 2x4ft area — a larger space is required for seedlings. It consumes 200 watts of electricity. An adjustable ballast is incorporated. LEDs and drivers of superior quality (Samsung and Mean Well)
- Price-performance ratio is the best available
Does the SF-2000 get hot?
It does generate some heat, as do all grow lights, but the amount is tolerable. Maintain proper air circulation and temperature control in the room where your 2×4 grow tent is positioned.
What height do I hang the SF-2000?
It is safe to hang this light at a height of 18 inches throughout vegetative and blooming stages, and at a height of 28 inches for seedlings. If you don’t have enough room to raise the light, you may always dim it; however, you’ll have to unscrew the driver from the board in order to get to the dimming screw, which is located on the bottom of the driver, which will need some effort.

Designed specifically for use in 2×4 foot grow tents, the Green Sunshine Electric Sky ES300 is a high-end LED grow light. This is a high-intensity grow light with a spectrum that has been specially tailored. You’ll have to pay a premium in exchange for this. But it’s well worth the effort. Because the Green Sunshine Company feels that most grow light spectrums lack sufficient infrared, the ES300 generates greater amounts of infrared and red than is often seen in grow lights. The following is a breakdown of the colors: Blue makes up approximately 10% of the spectrum; green makes up 25% of the spectrum; red makes up 55% of the spectrum; and infrared makes up 10% of the spectrum.
- The University of Michigan conducted an experiment to see if the incorporation of green light is beneficial to plant development when compared to other typical spectrum makeups.
- According to the Green Sunshine Company, “With the unique high-dose of near-infrared light, huge blooms commence earlier, vegetation develops quicker, and the plant makes more effective use of light from what is known as the Emerson Effect.
- What you said piqued my interest immediately.
- Finally, take a look at the light intensity when it is suspended 18 inches over the canopy of a 2×4 foot grow tent: That is an astounding quantity of light spread throughout the whole 2×4 foot footprint of the grow tent.
ES300 Key Specifications:
- A 2×4 foot grow tent will produce flowers. Provides a broader area for seedlings to grow
- It consumes 300 watts of electricity and has dimming capabilities. Extremely high performance in a 2×4 configuration
- The heat sink frame effectively dissipates heat.
What Height to Hang The Green Sunshine ES300:
Because of the unique lenses on the ES 300, you can get the light extremely near to the plants without burning them.
The Green Sunshine Company specifically indicates that the light may be suspended as low as 12 to 15 inches above your canopy during the flowering phase, despite the fact that the intensity values above are from the normal 18-inch height. That’s quite an accomplishment.

Growing in a 2×4 foot grow tent with the HLG 260 watt QB (quantum board) is a popular option for growers that don’t mind spending a few minutes putting it together. This is the XL variant, which means that the main board is longer than usual, allowing for greater space between the LED boards, which results in improved light uniformity. It is an excellent choice for a 2×4 space since you are receiving HLG quality and performance at a reasonable price with the HLG 260 watt quantum board. Assembling the light yourself enables them to sell the board at a lower cost than they otherwise would.
HLG 260 Watt QB XL Key Specifications:
- A 2×4 foot area is sufficient
- No soldering is required. Only a screwdriver and a wire remover are required. At 2.7 umol/Joule, it is extremely energy efficient
- It consumes 260 watts. Driver with dimming capability
- Included is a hanging kit. Color temperature of 3500K with red wavelength of 660nm (see below)
Here’s a look at the intensity when the light was tested in open air:
Keep in mind that this is an open-air test, and that when you install the HLG 260 watt QB into your grow tent, the reflecting walls will enhance the light intensity much higher than it already is. The temperature in the spectrum is 3500K, which is usually considered to be the optimal temperature for growing cannabis at all stages of growth. Additionally, the lamp has 660nm red LEDs, which guarantee that there is enough red light to support a vigorous blooming cycle.

After reading my lists, many growers contact me to seek for my advice. My personal preference for a 2×4 foot grow tent would be either the Spider Farmer SF-2000 or the Green Sunshine ES300, both of which are available on Amazon. Both of these lights are excellent choices, and I believe you will be pleased with any one. The HLG is also a very nice camera, but it faces stiff competition from the SF-2000, which is significantly less expensive. The Phlizon Linear Series PH-3000 received an honorable mention.
I don’t advocate the 150w high-pressure sodium lamp, although I do talk to folks who are on a limited budget from time to time.
FAQ:
A 2×4 foot grow tent may accommodate up to 40 watts per plant, while the best grow lights require at least 200 watts for the entire tent to function well.
How many cannabis plants fit in a 2×4 grow tent?
In a 2×4 grow tent, two to three cannabis plants can be accommodated.
According to how huge the plants are permitted to grow, the price might fluctuate.
What size inline fan should I use in a 2×4 grow tent?
For a 2×4 grow tent, an inline fan with a capacity of 100 cfm to 120 cfm will be sufficient ventilation.
How do I control temperatures in a 2×4 grow tent?
Open a window or turn on an air conditioner if your grow tent is becoming too hot. You can also try cooling the room where the tent is situated. If the temperature inside the grow tent is too low, you may need to purchase a space heater for the room where the tent is placed.
How do I control humidity in a 2×4 grow tent?
The use of a humidifier or dehumidifier in your grow tent will allow you to regulate the humidity level. References:
How Many Autoflowers Fit in a 3×3 (90×90 cm) Grow Tent?
Autoflowers are a simple and cost-effective method to get started cultivating cannabis indoors. They grow rather quickly, need little upkeep, and transition seamlessly from vegetative to blooming stages. The disadvantage of autoflowering plants is that they are more susceptible to topping, pruning, and defoliating than other types of plants. As a result, plants require less upkeep, but they are also less well-trained. Because we, as gardeners, are unable to prune them as much as we do picture plants, autos tend to grow taller and slankier than photo plants.
Choosing the most appropriate quantum board LED grow light for a 3′ by 3′ tent
The size of plants is determined by the strain, the size of the pot they grow in, and how well the grower takes care of the plants.
This means that the number of plants in a particular space will vary slightly based on the growth circumstances that are available. The following assumptions are made: autoflower weed plants are grown in large containers (4+ gallon, 15+ liters), are well-fed with nutrients, are exposed to plenty of light, and the strain naturally grows wide and busy, four mature plants (two rows with two plants per row) will fit in a three-foot by three-foot (90-centimeter) tent When autoflower plants are grown in small pots (3 gallon, 10 liter), are given restricted nutrients and light, and are otherwise neglected, they will be reduced in size and may be crammed into a 3’3′ tent with nine plants (three rows with three plants per row) as a result.
- Presented here is a 2.52.5′ (8080 centimeter) tent that has two mature autoflower (Auto AK-47) plants: There’s lots of space surrounding the plants, and two more plants might have easily been accommodated in this 6.25 sq foot space.
- To sum it all up: A 3 by 3 ft.
- The amount of plants produced is determined by the size of the pots used and how well they are cared after.
- This implies that more plants (9) may be squeezed into the 3 3′ space.
How Many LED Watts Are Required Per Square Foot of Grow Space?
*This article was last updated in May 2018. Are you a newcomer to the world of LED cultivation? If this is the case, the charts below will assist you in determining how much energy (measured in watts) your plants require to blossom. Disclaimer: Wattage is a legacy of the days of high-intensity discharge (HID) lamps (MH and HPS). The coverage area of a fixture or the utility of an LED grow light should not be determined by the wattage of the fixture or the LED grow light. Using wattage as a simple technique of estimating the optimal fixture size for your grow should be limited to the most basic of situations.
PPFD (and spectrum) are essential components of a good grow when used in conjunction with the appropriate spectrum for your plant type and development phase.
The term “wattage” in this article refers to the amount of electricity that is pulled from the wall, not to the amount of electricity that is drawn from the LEDs, which is normally the product of the maximum LED wattage multiplied by the number of LEDs specified by the manufacturer.
For example, a 900 watt LED grow light would be made up of 300 x 3-watt LEDs. The LED grow light, on the other hand, may only consume 500 watts when connected to the wall.
Grow variables
It is critical to note that the amount of actual watts that you will use for your grow will vary based on the following factors:
- Plants that require a lot of light, such as tomatoes, peppers, and other vegetables
- Plants that require little light, such as herbs and leafy greens (such as basil lettuce)
- There is a significant difference in the quantity of light required by seedlings, vegetative, and blooming plants.
Watts per square foot
For blooming, the typical LED grow lamp consumes around 32 watts to cover 1 square foot. This is in stark contrast to a conventional HID lamp, which consumes 40 watts per square foot (assuming a 5′ x 5′ space or a coverage area of 25 square feet). The use of a HID in a 4′ x 4′ area will increase the power coverage to 62.5 watts per square foot (psf). (The energy savings that growers may expect from employing LED grow lights instead of high-intensity discharge lights is around 38 percent.) This energy savings figure solely includes the savings that farmers realize as a result of utilizing LED lighting fixtures.
For example, depending on the size of the setup and the temperature of the surrounding environment, less ventilation and air conditioning may be employed, or it may be altogether avoided.
More energy-efficient LED grow lights will consume fewer watts to produce the same amount of light that a less energy-efficient LED grow light would provide.
LED Wattage Chart Explanation
The wattages indicated below are based on the assumption that you are blooming your plants. If you’re growing vegetables, you might want to consider reducing your wattage by 50% because vegging plants only require roughly half the amount of light that flowering plants do. As is always the case, following the manufacturer’s advice is the best course of action.
Using the charts
The following columns will be included in each of the charts:
- Plants to be cultivated in a certain area The area covered by a certain number of plants in terms of square footage
- The recommended LED wattage is based on the quantity of plants being grown in the given space.
Wattage charts
For blooming, assume a wattage of around 32 watts per square foot (real LED wattage). Smaller yields may be associated with lower wattage, whereas bigger yields may be associated with higher wattage.

Two plants are plenty for that amount of soil area. Vegged in 5 or 6 weeks from seed, or 3 weeks from clone, depending on the variety. With fewer plants, life will be less complicated. 2 will perform admirably. 420 Magazine Mobile App was used to send this message from my iPhone. Thank you for your responses! It appears that the majority is in favor of option 2. Dark Angel and Purple Kush strains from CKS’s are on their way to me. Is it possible to plant one of each kind, or should I stick to one strain?
- If you wish to experiment with several different strains at the same time, there is no compelling reason not to try one of each.
- I’ll do three hydro in my flower and just two moms in my flower, as well as numerous soil in my flower, depending on the situation.
- That was my most recent harvest, and plant training took one month.
- I taught her to have nine tops that were equal to that one, as well as a large amount of popcorn for creating oils.

I’ve seen that many individuals are stating that only two plants are needed. I would recommend at least 6-8 plants for a good start. Everything is dependent on your growing style. You may do one giant plant, or two large plants, or six to eight smaller plants, or twenty very little plants, or any combination of these. It all really depends on what you want to accomplish with your life. If you live in a state where you are restricted by the number of plants you can have, then that is your limit.

I understand your frustration, icemud, however you can maximize that area by growing two plants in 22-litre smart pots for a maximum of three to four weeks of veg. You’d still obtain the maximum grams per square foot even if you just had two plants.
There will be less work and fewer issues for the law. I’d think you’re looking at getting between 5-9 ounces from those two plants, and if anyone can pull more from that space, please share your secret with me. 420 Magazine Mobile App was used to send this message from my iPhone.

Major PITA
2 large plants or 6 tiny plants are recommended. Dimensions and quality have absolutely nothing to do with one another. In a SoG, you can grow monster plants of excellent quality, or you can produce monster plants of poor quality. More little plants need more care, but they allow you to change the area over more quickly, which may result in a higher yield over the long term. It also provides you with some back-ups in case one or two of the originals need to be eliminated. When working in a confined location, I’d recommend sticking with the same strain because it would be tough to accommodate strains with varying growth tendencies.
