In order to get the number of plants required, multiply the square footage of the planting bed by the number of plants required per square foot. Predict the amount of square footage you will need for each plant if you are employing plants with various spacing needs in the same location. The number of plants per square foot is measured in units of plants per square foot.

How far apart do you plant plants?

The usual rule of thumb is to space plants according to the estimated width of the plants when they are fully mature. For example, a tree that is predicted to grow to be 40 feet wide would be planted 40 feet apart from the next tree of the same kind in order to maximize growth potential.

How far apart should you plant plants?

How Many Plants in a Grow Tent / Grow Room?

It is important to cultivate the appropriate quantity and size of plants in order to provide a satisfactory harvest. Make sure you don’t overload your tent with too many plants. Overcrowding plants will not result in an increase in yield. Instead, you’re more likely to limit growth and reduce your harvest’s output. Often, fewer, larger plants can produce just as much, if not more, than a larger number of smaller plants. So, how many plants do you recommend growing in a tentor room? The actual number of plants required is dependent on a variety of factors, including the following:

  • The height and width of your plants
  • Your growth system (the form of the pots, the distance between the pots, the size of the pots, and so on)
  • Your greenhouse lights
  • The remainder of your camping stuff is in your tent.
See also:  How To Hang Tarp Over Tent

The most important thing to remember is to provide adequate space around plants to allow for lateral development.

You don’t just want your plants to be tall; you also want them to be large and bushy in appearance. As a general rule of thumb, you should aim for 1 – 4 plants per square metre of garden space.

Some people allow their plants to become too big during vegetative growth, and fail to leave room for any growth in flowering. By the end of the veg period, plants should be around half their final size. With that in mind, keep the veg period relatively short if you can only accommodate small plants.If you want to let them develop but haven’t got space for the extra growth, you’re going to need a bigger room or tent.

Tent Guide

You have the option of growing more little plants or fewer big plants. Here’s what we propose for our primary tent sizes based on our experience:

Tent Guide
Number of Plants
75cm x 75cm 1 – 2 plants
100cm x 100cm 1 – 3 plants
120cm x 120cm (XL) 1 – 4 plants
100cm x 150cm 1 – 4 plants
120cm x 240cm (XXL) 2 – 8 plants
150cm x 150cm 2 – 6 plants
150cm x 200cm 2 – 8 plants
150cm x 300cm 4 – 12 plants
100cm x 300cm 3 – 9 plants
200cm x 200cm 4 – 12 plants
200cm x 300cm 4 – 16 plants
240cm x 240cm 4 – 16 plants
360cm x 240cm 6 – 24 plants
300cm x 300cm 6 – 24 plants
600cm x 300cm 12 – 48 plants

If your tent size isn’t on this list, you’ll just have to perform some quick arithmetic to figure it out:

Step 1
Work out how much floor space you have.Multiply your tent’s L x W (length x width)e.g. a 3m x 3m x 2m tent has 3 x 3 = 9 sq.m of floor space.
Step 2
Work out:(floor space) x (number of plants you want to grow per sq.m)(e.g. a 9 sq.m x 3 plants = 18 pot system) Remember– we recommend 1 – 4 plants per sq. m.

Maximise Floor Space

There are a few various approaches you may use to maximize the amount of accessible floor space you have.

1.Use Expando Tent Supports

If you have a limited amount of room in your tent, consider using Expando Tent Supports. They help to keep your tent canvas taut while also increasing the size of your growing space by up to 30cm (depending on the tightness of your canvas). That equates to 7.5cm per wall. They are designed to accommodate tents that are:

  • Are one meter or longer
  • Have poles ranging from 16mm to 28mm in diameter
  • Tent poles should be spaced 1 – 1.5 meters apart.

2.Use a taller tentlow-profile system

Plants grow too near to their light source, which some growers are unable to shift because of a shortage of headroom, and as a result, some growers find they are unable to enable their plants to reach their full potential. When this occurs, they shorten their vegetative cycle and begin blooming earlier in the season than usual. Consider using a higher 2.2m or 2.4m grow tent (you may require a more powerful light as a result) and/or a low-profile system to avoid this from happening. This will allow you to maintain a safe distance between your grow lights and the canopy over them.

  1. The end result is that you simply have more area in your tent for plant mass.
  2. In addition to making sure the number of pots you use corresponds to the number of plants you want to cultivate, you must make certain that the system physically fits into your tent before purchasing it.
  3. You have more options when it comes to how you connect and where you place the pots.
  4. As a result, you may customize your system to fit the design of your tent.
  5. In the case of NFT systems, they are precisely the size and shape that they are.

What Size Pots?

If you’re utilizing a pot-based method, you’ll need to determine the number of plants you’ll be growing and the size of the pots you’ll be using once you’ve determined the number of plants you’ll be growing. For every 1–1.2m2 of tent space, you should use 50–60L of growth medium, according to the manufacturer’s recommendations. 50 – 60L will fill the following: As an example, if you wanted to grow four plants in a 120cm by 120cm space, you would need four 12L pots. Alternatively, you may use four 12L pots.

We recommend
We always recommend usingRhizoPots, which are made from fabric. They allow air to contact root tips and ‘air prune’ roots. When this happens, rather than simply growing forwards, towards the edge of pots, roots start branching and producing secondary and tertiary roots.Overall, you end up with a denser root network that’s spread more evenly through the media, giving plants access to the nutrients and water in the central space. You also get more root tips for extra uptake.

How Many Plants Can I Fit in a X by X Grow Tent?

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.

To guarantee that the plant spreads broad and fills the tent with as many bud sites as possible without growing too tall, you would want to apply low stress training and/or other strategies.

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. However, because you go from vegetative to flowering so fast, it takes considerably less time to get from the beginning to the end of the harvest, allowing you to harvest more frequently if you grow all year.


  • 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)


  • 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.

  1. Depending on the size of the object, that is.
  2. 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.
  3. 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.
  4. Furthermore, development behind the net is eliminated since it does not receive much light in the first place.


  • 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.


  • 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.

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. Alternatively, you might utilize an intake fan to counteract the force of the exhaust fan.

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.

How Many Plants to Maximize Grow Space?

Nebula Haze is the author of this piece. If you’re getting ready to start producing cannabis, you’ll need to make a choice about how many plants you want to produce. This is one of the most often asked questions I receive from beginner growers, and it’s fantastic that you’re asking it since it’s actually rather crucial. If you cultivate too many or too few plants, you may not receive the yields you desire, and it may take longer than necessary to reach to the point of harvest. Finding the proper quantity of plants to fulfill your objectives can be a difficult balancing act to achieve success.

  • If you cultivate more than 8 plants under a single grow light, there is a good probability that you are reducing your yields by not providing each plant with sufficient space to thrive.
  • There are too many plants in the accompanying photo to let them to develop all the way to harvest under a single grow lamp — each plant will not receive enough light and room to create a sufficient quantity of thick bud.
  • Growing fewer plants in larger pots would most likely result in greater yields for this gardener.
  • It is my goal to walk you through the process of selecting the optimal amount of plants for your setup in order to optimize yields and harvest as soon as feasible!
  • The size of the grow space
  • The kind and size of the containers
  • Grow light, ease of growth, and yields are all important considerations. Desired timetable (when do you want to harvest the crops? )
  • And

The Size of the Grow Space The overall amount of space available in your grow area has an impact on the number of containers that can be accommodated. Because tiny containers take up less physical room than large containers, you will be able to physically fit more into your grow area than if you were using large containers. If you’re growing in large pots (for example, a DWC reservoir), you may only be able to put one or two plants in your grow space before you run out of room. Because of the massive size of the DWC reservoir, there isn’t much room left in this grow tent for another container.

Smaller pots may sustain smaller plants, while larger containers are required if you wish to grow large plants.

(See the whole guide for more information.) You can only grow a certain number of plants in your grow room because of the amount of plant containers you can physically fit in it.

Once you’ve determined the size of the container(s) you’ll be using, you’ll be able to determine the maximum number of containers that will physically fit in your grow space. As a general guideline, if your final (desired) plant size is. for hand-watered plants, you should.

  • 12′′ x 2-3 gallon containers
  • 24′′ x 3-5 gallon containers
  • 36′′ x 5-7 gallon containers
  • 48′′ x 6-10 gallon containers
  • 60′′ x 8-10+ gallon containers

Plants in too-small containers might suffer from stunted growth and develop symptoms that appear to be caused by nutritional shortages. Find out how to transfer plants into a larger container. Ample room surrounding each plant container is required in order to accommodate the appropriate plant size! Keep in mind that each plant will most likely grow to be larger than the breadth of its container and will want additional space to extend its wings! Consider how large you want each plant to grow, and make sure there is enough space surrounding each container to accommodate the plant you choose.

  • The type of grow lamp you employ influences the amount of total available light coverage you have (how much space can actually support plants).
  • You can only develop bright plants inside the “light footprint” of a grow lamp – that is, within the area where the plant receives direct sunlight.
  • If you so wish, you may actually measure your light footprint directly using a low-cost lux meter if necessary.
  • For compact fluorescent lights (CFLs) and other fluorescents (such as the T5), the light footprint covers just the area directly beneath the bulbs, because the light (which is useful to plants) emitted by fluorescent lighting does not reach more than a few inches.
  • As a result, how you set your CFLs or fluorescents will determine the total footprint.
  • If you’re using MH/HPS, your light footprint looks like this:
  • A 150-watt light bulb covers a 2-foot-by-2-foot (0.6-meter-by-0.6-meter) space
  • A 250-watt light bulb covers a 2-foot-by-2-foot (0.6-meter-by-0.6-meter) area up to 2.5-foot-by-2.5-foot (0.8-meter-by-0.8-meter)
  • 400-watt light bulb covers a 3-foot-by-3-foot (0.9-meter-by-0.9-meter) area up to a

A 150W HPS grow light can cover up to a 2’x2′ area, so all the plants in this picture are getting good light levels. However, any plants outside that main area would be starved for light. You can actually see the corners of this tent are in shadow. When it comes to LEDs, the light footprint varies depending on the model, and you can find out what it is by contacting the manufacturer directly. Feel free to check out ashort list of some cannabis-tested LED grow lightswhich includes their light footprint information.

  • The result is that any plants growing within the footprint of the lamp will be fine, but any plants growing outside of the footprint will not receive enough light.
  • A plant that receives less light than this likely will never get big enough to produce a significant amount of bud, or buds will be airy.
  • HPS/LED:At least 75W per plant CFL/T5:At least 150W per plant As an example, if you had a 400W HPS grow light, you use the formula this way: Take 400÷75=5.3.
  • If you had 400W worth of CFLs, you would take 400÷150=2.6.
  • It’s important to keep in mind that these figures arebare minimums!
  • Desired Ease of Growing The number of plants you grow affects the overall ease of growing.
  • Plants often need to be watered and trained individually, plus if you have more than one row of plants it can be really difficult to tend to the plants that are all the way in the back.
  • When you are growing lot of plants of different strains at once there’s more of a chance that some of the plants will grow very differently from the others, which can be frustrating.
  • If you choose different strains, you may be surprised at how differently they grow in the exact same environment!

Desired Timeline + Yields (Howsoonand howmuchdo you want to harvest?) The amount of yield you can achieve with a good grow is determined less by the number of plants and more by yourstrain,skillandgrow light(learn more about what determines your yields) (learn more about what determines your yields).

  • But the timeline (how long it takes until harvest) is partially determined by how many plants you choose to grow, and this indirectly affects your yields.
  • A single plant needs enough time to grow big enough to support all the buds you want to harvest.
  • This single plant needed almost 8 weeks in the vegetative stage to get big enough to fill in most of the grow tent Butif you were growing 2 plants in the same setup, each one would only need to grow half the size in the vegetative stage to achieve the same amount of coverage under the light.
  • Less wasted light = more total growth.
  • This fact can be used to shorten your veg stage because whether you’re growing one plant or many, once you’ve achieved that coverage in the vegetative stage you’ll end up getting similar yields at harvest.
  • Together, these 4 plants have created a canopy that is a similar shape, length and width as the single plant above.
  • However, they only needed 6 weeks in the vegetative stage to achieve this size (2 weeks less veg time than the single plant above) so were able to switch the flowering stage sooner.

And a shorter vegetative stage ends up saving you electricity and time!

So in some ways when it comes to timelines/yields and number of plants, it’s a matter of deciding how much personal time you want to put in to your grow on a regular basis vs how much time you are willing to wait to get to harvest.

If you want a grow that’s easier and less time-consuming, opt for fewer plants.

This lets you choose the best plants of the bunch and not be stuck with any weaklings that just aren’t growing as well as the others.

This grower started with 6 plants even though they only planned on growing out two.

Start with Feminized Seeds With non-feminized seeds, about half of your plants will end up being male (which need to be thrown away) and that can seriously mess with your plant numbers.

This can make it hard to plan for the number of plants, because on average you would expect to get 3 females from 6 non-feminized seeds.

With feminized seeds, all your plants will end up being bud-bearing female plants, which means you get to keep all your plants.

This is true for just about every indoor growing setup that uses grow lights.

Plus it’s free!

Example of themanifoldingtechnique in action, which is a specific way to train the plant in the early vegetative stage to create multiple big colas instead of just one.

When a plant is not trained, it only produces one main bud per plant.

It will reduce your overall yields indoors because only the single bud closest to the light will get big and fat.

How Many Cannabis Plants Can You Grow Per Square Metre? [Calculators Inside] – RQS Blog

A 150W HPS grow lamp can illuminate a 2’x2′ space, which means that all of the plants in this photo are receiving adequate light levels. Any plants outside of that core region, on the other hand, would be deprived of light. The corners of this tent are genuinely in shadow, as can be seen in the photo. As for LEDs, the size and shape of their light footprint vary depending on the type, and you may find out more about them by contacting the manufacturer. Please feel free to browse through a brief selection of several cannabis-tested LED grow lights, which contains information on their light footprint.

  • That implies that any plants growing inside the footprint of the lamp will be alright, but any plants growing outside of the footprint will not receive enough light from the light source.
  • A plant that receives less light than this will most likely never grow large enough to produce a considerable volume of bud, or the buds will be light and airy in appearance.
  • HPS/LED: A minimum of 75W per plant is required.
  • For example, if you have a 400W high-pressure sodium (HPS) grow light, you would use the following formula: Consider the number 40075=5.3.
  • In the case of 400W worth of CFLs, the formula would be 400150=2.6.
  • It’s vital to remember that these are only the basic minimal statistics!
  • Growing Ease That Is Desired The overall ease of growth is influenced by the quantity of plants you have in your garden.
  • Plants frequently require particular attention, such as watering and training, and if you have more than one row of plants, it can be tough to keep up with the plants in the back of the garden.
  • Growing a large number of plants from various strains at the same time increases the likelihood that some of the plants may grow in a very different manner from the others, which can be irritating.
  • Choosing different strains of cannabis may amaze you with how differently they grow in the exact same environment!

Expected Timeline + Expected Yields (When do you want to harvest and how much do you want to harvest?) In a good grow, the quantity of yield you can get is governed less by the number of plants you have and more by your strain, expertise, and grow light (learn more about what determines your yields).

  1. However, the timeline (the amount of time it takes till harvest) is partially governed by the number of plants you select to cultivate, and this has an indirect effect on your yields.
  2. A single plant need sufficient time to develop into a large enough structure to sustain all of the buds you intend to harvest.
  3. This single plant required over 8 weeks in the vegetative stage before it was large enough to cover the majority of the grow tent.
  4. This is due to the fact that a single seedling has less leaf mass and, as a result, cannot utilize as much light as a pair of seedlings.
  5. If you were to cultivate four plants, each one would only need to develop to a quarter of its original size in order to provide the same amount of covering during the vegetative stage.
  6. After all, whether you’re growing one plant or a hundred, as long as you accomplish that coverage in the vegetative stage, you’ll end up with identical yields at harvest.
  7. These four plants have joined together to form a canopy that is comparable in shape, length, and width to the single plant above.

However, because they only needed 6 weeks in the vegetative stage to reach this size (2 weeks less veg time than the single plant above), they were able to transition into the blooming stage far sooner than the single plant.

In addition, a shorter vegetative period results in energy and time savings for you!

Consequently, when it comes to timelines/yields and the quantity of plants, it’s a question of selecting how much personal time you want to devote into your grow on a regular basis against how long you are willing to wait before harvesting your crop.

Make your grow easier to manage and less time-consuming by growing fewer plants.

In general, it’s a good idea to start with more plants than you need when growing your first crop (and especially when growing for the first time).

Furthermore, you never know when a seed may fail to germinate or will be accompanied by a condition such as a poor mutation.

It will not impede your growth if one of the plants is weak or if one of the seeds doesn’t germinate because of a weakling.

When using non-feminized seeds, around half of your plants will wind up being male (and will need to be thrown away), which can have a significant impact on your plant population.

This makes it difficult to estimate the number of plants you will need because, on average, you would expect to obtain three females from every six non-feminized seeds.

With feminized seeds, all of your plants will wind up being female plants that produce buds, which means you will be able to keep every one of your plants.

Plant training can help you increase yields by filling up your growing space.

In fact, this holds true for virtually every indoor growth configuration that makes use of grow lights.

Plus, it’s completely free!

This is an example of themanifoldingtechnique in action, which is a specialized strategy to educate the plant in the early vegetative stage to produce several large colas rather than a single large cola.

The primary bud of a plant only develops on a single plant if it has not been trained.

Indoors, it will limit your total yields since just the one bud nearest to the light will grow large and fat, reducing the entire output.

What Kind of Nutrients Should I Include in My Diet? The Best Grow Light: How Do I Choose One? How NOT to Get Caught Growing Weed Using Stealth Techniques.


In addition to your tent’s available area, the size of the pots you use, and the type of lighting you use, there are numerous more elements that determine the number of plants you can properly put into a square metre.


The first thing to think about is the sort of cannabis you’re growing—the genetics of the strain you’re using. Sativas grow tall and lean, but indicas are stocky and bushier in appearance. Autoflowers are known for their short growth, with some types reaching barely 50–60cm in height. When growing cannabis indoors, even people who do not have major space constraints are more likely to prefer shorter cannabis cultivars. As the person responsible for supplying illumination, you must take into consideration the amount of space taken up by your growlights and other equipment.

In order to prevent problems with spacing and illumination if you do not intend to train your plants, try growing the same sort of strain or two strains with very similar heights to avoid running into problems.

It is entirely up to you to determine whether you would want to harvest a large number of little autoflowers or simply one or two really powerful hybrids.


The dimensions of your growing space will have a significant impact on the number of plants you can grow per square metre, as well as on your overall yield. If you’re like the majority of home growers, you’ll most likely be utilizing a grow tent that has been put up in a convenient area in your house. Grow tents are available in a variety of sizes, ranging from modest 50 x 50cm tents to big tents that might take up half of your living space. Choosing the appropriate size for your grow relies on the strain(s) you’re growing, the size of your indoor growing area, and the style of grow you’re aiming for (heavy training, leaving plants to develop as is, etc.).

As you grow your collection of plants, you’ll need to scale up your operation.


Depending on the diameter of your pots, you can put many of them into a square metre of space. However, the size of your containers has an influence not only on the number of plants that can be accommodated per square metre, but also on the total size of the plants. To put it another way, the larger the pots you use, the larger the plants that grow in them. Pot sizes are recommended in the following proportions: 12 litres (one gallon): Seedlings and young plants up to 15cm in height are OK. Approximately 2–3 litres: Plants may grow to a maximum height of 25cm.

The following amounts are in litres: 11 litres or more Plants grow to an average height (check strain description) You can accommodate nine 11-litre pots per square metre of floor space for a typical indoor grow.

You’ll be wasting crucial floor space if you use spherical planting pots. Make use of our planting pot calculator to choose the most appropriate container size for your cannabis plants. Plants per square meter of space


With planttraining techniques, you may minimize the number of cannabis plants to a bare minimum while yet maximizing their yield and quality. Each of these training strategies is intended to maximize space while also increasing yields.


4–16 plants per square metre are recommended. Outcomes: Fast yield, maintains plants short, is simple to conduct, and produces proportionally lesser yields per plant than other methods. When it comes to the sea of green approach (SOG), it is all about making the most of the area you have available. Photoperiod plants, clones, and autoflowers can all benefit from this method since it produces consistent results. This strategy is both time-efficient and profitable. After 1–2 weeks of vegetative development, plants are forced to blossom in a SOG, which reduces the amount of time they have to grow.

As a result of the lack of time available to the plants, the result is a large number of short plants with short primary colas.

An optimum SOG grow may provide numerous 500g/m2 harvests each year from a single plot of land.


The average square metre has 2 large/5–10 tiny plants. Outcomes: Simple to implement, it maintains height under control, increases yield, and extends the growing period. Techniques like topping and fimming are used for high-stress training. Cutting off or pinching the primary growth tip of a plant causes the plant’s apical dominance to be broken, resulting in the development of numerous major colas instead of just one. The natural outcome of this is bushier growth, which eventually leads plants to stop growing in the shape of a Christmas tree.

If you’re pruning, topping, and/or fimming your plants, give them time to recuperate and count on a later harvest date as a result.


1 giant plant and 2–4 tiny plants per square metre of space Outcomes: It is difficult to achieve consistent results, but there are solutions for both novices and more skilled growers. Mainlining and lollipopping are two plant training strategies that are used to encourage the development of big buds at the ends of branching structures. Mainlining Mainlining consists of a combination of topping, LST, lollipopping, and ScrOG ingredients. Plants are topped at the third node, and all of the lower branches are removed from the plant.

This can drastically increase the amount of grow space required depending on the number of colas and the size of your pots, so bear in mind that you may be able to accommodate less mainlined plants per square metre of grow space.

In order to remove any extraneous development from the branches and the main stem, only the primary bud and side branches with large buds are left on the plant. The plant now concentrates its energy toward the huge buds, just as it did when it was mainlining.


Plants per square metre: 2–4 large/4–6 medium plants per square metre Results: Suitable for autoflowers (no topping required), perfect for novices, and does not necessitate any significant recuperation time. LSTis a training strategy that is suitable for beginners. During vegetative development, you’re essentially just bending and tying down stems in order to force plants to grow horizontally instead of vertically. LST can be used with other approaches, such as ScrOG, to get greater results. It is frequently performed in conjunction with topping in order to disrupt apical dominance, although it may also be conducted on autoflowers without the use of topping.

Plants trained per square meter of SQMGrowspace (m2) Training with a Low Stress Level (LST)


1–2 huge plants and 4 medium-sized plants should be planted per square metre. Outcomes: Only for expert gardeners who want the highest output per square metre and the greatest flexibility in terms of how many plants they wish to employ. A single square metre of growing space is most effectively utilized with the AScrOGmethod. It is a grid-like mesh (chicken wire, netting, or other similar material) through which the branches of budding cannabis plants are woven to restrict the growth of the plant in this advanced training method.

A ScrOG simply exposes the major colas to light, allowing the plant’s energy to be directed on bud development.

This manner, you can acquire the most yield possible from the space you have available for growth.

Even while you may fill your area with a single enormous plant in a giant 20l pot, you could alternatively grow numerous smaller plants in smaller pots, such as four medium-sized plants in each of four 10l pots.


The kind and intensity of your grow lights are the last factors that decide how many plants you can put into each square metre of your growing space. Growing awareness of the fact that grow lights do not distribute light equally throughout the full growing area makes this even more apparent. The highest light intensity (and, hence, the fattest buds) is found directly beneath the lamp, and the light intensity drops substantially as it moves to the sides. Growing fewer plants may make more sense in this situation because you will almost certainly be compromising yield due to inadequate light dispersion if you squeeze in too many.

Growing marijuana under HID (high-intensity discharge) lights can be difficult, but using a simple calculation will help you determine the appropriate amount of plants for your situation. Calculate the wattage of your light by multiplying it by 75 and rounding up the fractions.


  • In terms of plants, 150W HID =2 plants
  • 250W HID =3.3 or 4 plants
  • 400W HID =5.3 or 6 plants
  • 600W HID =8 plants
  • 1000W HID =13.3 or 14 plants

When utilizing compact fluorescent lights, multiply by 150. For example, consider the following while using a 400W CFL: 400 watts divided by 150 watts equals 2.6 or 3 plants


Modern LEDs produce the same amount of power as high-pressure sodium lamps while consuming only 60% of the energy. They are able to cover the same amount of space while using less power. A decent 250W LED is equivalent to a 400W high-pressure sodium lamp, which may cover around 5–6 plants. When compared to this, a high-powered 1200W LED should be able to illuminate around 8–9 plants. Keep in mind, however, that wattage is only one factor to consider when calculating the power of your LEDs, as a variety of other variables—including the type of LED—have an impact on their overall efficacy as well as their efficiency.

This sort of information is often made available by reputable producers.

  • TIP: If you’re not sure how many plants you want to cultivate, it’s best to start off with fewer plants to be on the safe side. It will be preferable in the long run to have two giant, happy plants with fat buds rather than a tent full of little, light-deprived cannabis plants that will only produce micro buds. As an added bonus, saving money on seeds is a possibility
