Ok, so you probably know what a grow tent is and the benefits it comes with. In this case, of course, we are talking about grow tents for indoor marijuana growth, and they come with many benefits such as good climate control, smell control, they keep pests at bay, and much more. However, how many plants can you fit in a grow tent, and specifically how many plants in a 6×6 tent?

When it comes down to it a 6×6 tent should be large enough to hold either 9 cannabis Sativa plants or 4 cannabis Indica plants. Yes, it does depend on what strain of weed you get. Remember that cannabis Indica strains tend to be a bit wider and bushier than cannabis Sativa strains.

A normal Sativa strain will need between 2 x 2 and 2.5 x 2.5 feet per plant, whereas your average Indica strain is going to need closer to 3 x 3 feet per plant. Let’s talk about this in some greater detail right now.

How Many Weed Plants Can You Fit In A 6×6 Tent?

Ok, so as we just mentioned above, a 6 x 6 grow tent is actually of a decent size and should be able to hold a decent number of plants. Now, you do have to do some math here, or really we have done it for you, but the point is that you can’t overcrowd your grow tent and there is a limit to how many you can fit in a certain space.

Because cannabis Indica plants grow wider and bushier than cannabis Sativa plants, which tend to grow taller and skinnier, you will be able to fit less Indica weed plants in the same grow tent as cannabis Sativa plants (we have covered the main differences between Sativa, Indica and Hybrids on this article) .

Generally, a Sativa plant will need at least 2 x 2 feet of space per plant, whereas an Indica plant will need closer to 3 x 3 feet of space per plant. Therefore, if it is a 6 x 6 foot grow tent we are talking about, you could fit either 4 cannabis Indica plants inside of it, or you could fit up to 9 cannabis Sativa plants.

Now, some cannabis Sativa strains will need a bit more room than 2 x 2 feet, maybe up to 2.5 x 2.5 feet, which would then mean that you could realistically only fit 6 Sativa plants in the same 6 x 6 foot grow tent, but they would have a lot of space to grow.

How Big Of A Grow Tent For 4 Plants?

Let’s always keep in mind how much room a single plant needs, which once again is 2 x 2 feet for a Sativa plant and 3 x 3 feet for an Indica plant. So, if you want to fit 4 plants in a single grow tent, how large does the tent need to be?

Well, if it is a Sativa plant we are talking about, which requires 2 x 2 feet per plant, this would mean that you would need a grow tent that is 4 x 4 feet in size for 4 Sativa plants.

If it is a cannabis Indica plant we are talking about, which needs 3 x 3 feet of space per plant, you will need a 6 x 6 grow tent for 4 Indica plants.

What Size Grow Tent For 6 Plants?

Just keep the math in mind here, 2 x 2 foot per Sativa plant and 3 x 3 feet per Indica plant. So, therefore, if you wanted to grow 6 Sativa plants, you would need a grow tent that is either 4 x 6 feet or 6 x 4 feet.

Remember that a 6 x 6 grow tent can fit up to 9 Sativa plants, which would be a square tent, but 6 Sativa plants will only need 6 x 4 feet.

On that same note, if you want to grow 6 Indica plants which each need 3 x 3 feet of space, you will need a grow tent that is either 9 x 6 feet or 6 x 9 feet in size.

Yeah, the math can get a bit complicated here, but if you are having trouble figuring it all out, just use some paper and a pen to draw yourself a little grid, and you should be able to figure it out no problem.

How Much Electricity Does A Grow Tent Use?

Technically speaking, a grow tent itself does not use any electricity whatsoever. It is not something that you can plug in to a power outlet. However, what is going to use electricity are the lights, the fans, the air ventilation systems, as well as your heaters and dehumidifiers (more on those here).

Calculating how much electricity a full grow tent uses is going to depend on many factors;

How Many Plants You have

For one, it is going to depend on how many plants you have and how big the tent is, especially in relation to the type, number, size, and strength of lights you have.

Your Climate

Moreover, it also depends on how warm and humid your climate is. Remember that weed plants need a certain temperature and humidity level to survive, so if you live in a really cold and dry climate, using a heater will jack up your energy bill.

If you live in a hot and humid climate, using your ventilation system as well as a dehumidifier is going to use a lot of energy too.

What Lights You Are Using (and how many)

When it comes down to it, you need to figure out what kind of lights you need for a certain number of plants, and how much energy each of those lights uses.

This can be quite complicated, and it is something we discuss in further detail in our articles about the best full spectrum grow lights (you can read it here), and other informational articles in regards to cannabis plants and their lighting needs.

How Many Plants Can You Grow In A 4×4 Tent?

Let’s just keep in mind the general space requirements of each weed plant, both for Sativa and Indica plants. Seeing as Sativa plants require roughly 2 x 2 feet of space per plant, you could fit 4 of them into a 4 x 4 foot grow tent.

However, because cannabis Indica plants require roughly 3 x 3 feet of space per plant, realistically, you could only fit 1 single cannabis Indica plant into a 4 x 4 foot grow tent.

Don’t Overcrowd Your Grow Tent!

The main takeaway that you need to keep in mind here today is that you should never overcrowd your grow tent. If a grow tent is overcrowded, it makes it very hard for all of the plants to get the ideal amount of light.

The more leaves there are and the less free space there is, the harder of a time the light will have penetrating down to the bottom.

Moreover, having more plants in a tight space also means that the temperature and humidity levels will be harder to manage.

It’s better to put less plants in the same grow tent and get better end results, than it is to cram as many plants into a grow tent as you can. Overcrowding a grow tent is just not worth it.


The bottom line is that cannabis plants do need a decent amount of space to grow. Just remember how much room both Indica and Sativa strains need to grow comfortably, and you should have no problems figuring out exactly how big of a grow tent you need for a given number of plants.

The most important thing to keep in mind here is that overcrowding a grow tent never turns out well.
