How Many Plants Can You Fit in a Grow Tent

Grow Tents are some of the latest innovations when it comes to the world of agriculture and plant care. Thanks to these grow tents, you are able to keep produce growing all year round, regardless of the season, or the current weather.

In the conventional means of growing plants, which would entail planting in soil, with its growth to be greatly dependent on the factors that were mentioned earlier.

With grow tents, however, you make use of a hydroponic system, which require water and an inert medium in order for the plants to grow, while keeping several factors in a more controlled environment, specifically heat and humidity that the plants are exposed to.

One of the most common concerns we associate with grow tents is the amount of plants you can fit in a grow tent. The reason for this is rather obvious, since they are usually placed in limited space indoors.

Moreover, one of the reasons why accommodation is an issue is simply because these grow tents are small in size, with some boxes measuring a mere 30 ft. across all possible dimensions.

Given the limited space, it is therefore important to make the most out of it, deciding carefully on the several factors that would determine the over-all capacity of the grow tent, each of which would be thoroughly discussed below.

Effects of Crowded Tents

Insufficient, Uneven Distribution of Plant Essentials

The plant essentials that we’re talking about here include water, air circulation and humidity, as well as the heat from the UV lamps that the grow tent would be needing.

It’s common sense that if you are going to cram in so many plants in the grow tent, some of these plants would not be getting the right amount of essentials, especially heat, given that smaller ones would most definitely end up being blocked by the larger ones.

Having more plants inside the grow tent would also be the cause of competition for air, as well as for water and the inert medium that’s used.

Faster Spreading of Plant Disease and Parasites 

Having a crammed interior, especially with hardly any space between the pots would mean that leaves would come in close contact with each other. This would mean that parasites, pathogens, mold, and other harmful microorganisms could easily cross from leaf to leaf or stem to stem.

Before you know it, plants belonging to the same row or column could all be infested or infected.

Eventual Destruction of Crops

The worst, and most obvious consequence if one is to place too many plants in the grow tent would have to be the death of crops. This would happen if the infected plants are not isolated or uprooted in the soonest possible time, or if no insecticide or antifungal medication of any sort would be sprayed or applied soon enough on these crops.

Determining Factors for Number

Type of Produce

It’s a given that different plants have over-all different sizes, determined by the diameter of stems, and the structure or pattern which the leaves usually grow in. One of the most common produce grown inside these grow tents would have to be Cannabis.

In the case of cannabis, it is advised that only 8 pots of Cannabis be placed inside. This ratio is ideal for every single standard LED light. Also, the broader the leaves, the wider the space is required.

Size of Grow Tent and Pots

Given that different tents have different manufacturers, the reality is that different grow tents would have different sizes as well. The larger the tent, the more plants you can stash inside the grow tent.

Making use of DWCs, or bigger plastics would also make you grow a significantly less amount of crops. Pots also greatly influence the quantity of plants you could put inside the grow tent.

Therefore, there are several pots you can choose to use. Making use of square pots is a better option in a sense that it’s much more space-efficient compared to the circular ones.

Grow Lamp Type Used

There are 2 different kinds of fixtures you can use to provide light, which would help substitute and simulate real-world sunlight. These options are CFL, or Compact Fluorescents, and LEDs, or Light-Emitting Diodes.

If you make use of 150 W for the latter type, then the space out to just be a 2’ x 2’, and if you would be having twice as large in terms of space, then you ought to increase the wattage.

For LEDs, on the other hand, you could use half the wattage ratings required if you would be making use of CFL, which makes it twice efficient. The total number of pots and plants you could place inside would depend on how many of these would be covered by the grow lamp.

The reason for this is simply because it would not be a good idea to put plants inside if all of them would not be directly exposed to the heat of the lamp, whether it be LED or CFL.


When it comes to knowing how many plants you can fit in a grow tent, there are several factors that would determine it and there will be no exact answer for this particular question. It is, however, important to keep in mind that cramming too many plants inside would definitely compromise its growth, as well as its ability to expand.

Always consider the natural size of the full-grown plant, given that some have more leaves than others. Also put the intensity of the light into consideration as well, and remember that square pots allow you to properly organize and store all of these plants in a much better way.

Since cannabis is a plant that’s popularly grown in these tents, it’s advised that one should not plant more than 8, but when it comes to other less-leafy plants, you may put a little bit more.
