If you have tried growing your own marijuana plants before, you know that one of the most important things is the space which you grow the plant in. Some people do it in a room, some in a closet, some choose to go with an outdoor grow op, and more. However, all of these types or styles of grow ops come with their own problems.

This is what the grow tent is for, but what is a grow tent used for? Well, a grow tent is a specialized tent, a square shaped tent, kind of like a box, which is more or less an indoor greenhouse for plants. A grow tent is used for growing marijuana, other herbs, and even vegetables sometimes, all indoors.

It’s definitely a convenient thing to have if you plan on growing a few marijuana plants indoors. Let’s take a closer look at these marijuana grow tents to see what they are all about.

What Is A Grow Tent?

A grow tent, simply put, is a tent which is used to grow marijuana plants in. Well, they are often used for marijuana plants now, but they were around before and have been used to grow herbs, tomatoes, and other plants, veggies, and fruits.

Now, although it is called a tent, it does not have that classic triangular shape. Grow tents are square or rectangular. They look more or less like a cardboard box turned on its side.

They will feature a large opening or door with a zipper for easy access. The inside of a grow tent will usually always feature some kind of reflective lining to help with lighting, a hole for ventilation (which can also be used to install a fan or ventilation system), and various racks or hangers for lights, fans, and other necessary equipment.

Using a grow tent to grow some marijuana plants is a good idea for many reasons. In essence, a grow tent is used to grow all kinds of plants indoors, kind of like a small, indoor, contained greenhouse.

8 Benefits Of A Grow Tent

Using a grow tent for your marijuana growing operation comes with a whole lot of benefits that you might have never thought of before.

Let’s go over the 8 main benefits that come with using a grow tent to grow marijuana plants.

1. No Need To Prepare A Space In Your Home

One of the really big benefits that comes with using a grow tent is that they are very space friendly and they eliminate the need to prepare a space in your home. Many people who grow at home choose to use a closet, which makes sense, but of course, it is not exactly ideal.

When you grow weed in a closet or small room, you have to install light fixtures, you need to put up reflective materials for the lights, install a ventilation system, and more.

There is also the fact that you end up sacrificing a room or closet in your home for this. A grow tent takes care of all of these problems for you.

2. It Increases Lighting Efficiency

Another big benefit that comes with using a grow tent is that it greatly increases the efficiency and power of your lighting system.

This is especially true because they already come outfitted with a reflective lining to reflect light and increase the overall intensity of the light, not to mention that it helps to supply your weed plants with light from all sides.

If you do not have a grow tent, you have to put up some kind of reflective lining of your own, something that is much easier said than done. A newbie grower with a closet might go for tinfoil and a staple gun, which works alright, but is not ideal.

The reflective lining inside of a grow tent is specially designed to maximize the power of your lights. This lets your plants grow faster and stronger, and it helps them become more potent as well.

3. It Helps Prevent Pest Infestations

Another really big benefit you get from using a grow tent is that it helps to prevent pest infestations. Yes, there are a lot of little pests which love to eat weed plants and make their home in the soil and on the leaves of your marijuana plant.

Pests like spider mites, aphids, and other flies, grubs, and spiders absolutely love those warm and humid growth conditions. If you just have your plant growing in a closet, or something similar, you are putting them at big risk for a pest infestation.

This can be absolutely disastrous. Best case scenario, they are present and eat some leaves, but worst case scenario, they destroy your plants, eat the roots, and multiply by the hundreds.

A good grow tent is sealed off and therefore keeps pests out for the most part.

4. They Help With Ventilation

The next helpful feature that you get from using a grow tent for weed growth is that they go a long way in helping with ventilation. To be happy and healthy, weed plants need a bit of a breeze going, they need a constant supply of fresh air and oxygen, and they cannot get too hot.

A grow tent is perfect for all of these things because they allow for accurate climate control. For one, they usually always come with a built in ventilation system.

Now, most won’t actually come with a fan, carbon filter (more on what they do, here), or carbon filter and fan combination, but they do come complete with integrated holes which allow you to install a ventilation or air filtration/ventilation system with ease.

The end result when growing weed in a grow tent is usually pretty good thanks to great ventilation and ease of climate control.

5. They Reduce Odors In Your Home

A big problem that you may have noticed with weed plants is that they will put out one heck of a strong odor. No, during the vegetative state, they will not really smell, but as soon as they begin to flower and develop buds, the odor a weed plant gives off is super strong, pungent, and recognizable.

The closer your plant gets to being ready to harvest, the bigger it is, the more of them you have, and the stronger and more potent the strain is, the stronger that weed plant odor can be.

It can be a real issue if you have a roommate or family members who do not enjoy the smell, or if you live somewhere you’d rather not attract the attention of you neighbors. (there are some good air fresheners that can help, we have covered them here).

A good grow tent combined with some odor reducing gel or a carbon filter will more or less eliminate the odors which come out of it, or at least keep the odor contained within the grow tent.

6. They Are Energy Efficient

The next benefit that comes along with using a grow tent for your marijuana grow up is because it helps to cut down on energy costs. Yes, a decent grow tent can cost you well over $100, but the investment is well worth the price (here is a full rundown on what it costs to grow indoors).

Not only do all of the above benefits which we have already spoken of apply, but these things also help you save lots of money in the long run.

For one, they assist with climate control, so your fans and other climate control equipment does not have to work as hard. Second, the lights work much more efficiently in a small space like this.

Yes, you could think of it in the way that your lights will work better and thus produce more potent and bigger yields, or you could also think of it in the way that due to the increased efficiency provided by grow tents, you can buy a slightly weaker light bulb and save money there.

7. Very Easy To Set Up

The next reason you might want to consider using a grow tent is because they make life a heck of a lot easier when it comes to setting up a grow operation.

Instead of having to worry about hangers or installing light fixtures, creating good ventilation (possibly having to cut or drill away parts of a wall to install a ventilation system), having to put up reflective materials, and more, a grow tent already has all of this done for you.

You can more or less plunk everything right into a grow tent, and you are good to go.

8. They Allow You To Grow Year Round

The final benefit that is attributed to the grow tent is that they allow you to grow year round. Yes, marijuana plants need certain conditions to grow right, especially in terms of humidity and ventilation.

You might live somewhere in a cold climate with a long winter, and many home heating systems just cannot keep up. During the winter, your home might be too dry and cool to allow for ideal weed growth.

A grow tent mitigates these problems and allows you to grow marijuana plants year round.

Drawbacks Of A Grow Tent

When it comes down to it, grow tents were made for a reason and they really do not have any drawbacks to speak of. Sure, the cost of the grow tent itself could be considered a drawback.

However, if you really think about it, the money you spend on a grow tent is an investment. You will get your money back many times over simply due to the fact that you will get more and better weed if you use one.

Perhaps the only other drawback of the grow tent to think of is that it limits the number of plants you can grow. Sure, your closet might be twice the size of an average growth tent, so you could fit more plants into it.

However, when it comes down to it, we would rather have 2 or 3 really nice weed plants with high yields and potent buds, thanks to a grow tent, than having 10 plants which did not turn out so well.

How To Choose The Right Grow Tent

Before you go out and buy a grow tent of your own, there are a few purchasing factors that you need to keep in mind. Here are the most important considerations to think of when purchasing a grow tent (we have covered a beginners buyers guide separately here).

1. Size

The most important thing that you are going to need to consider before making a purchase is how large the grow tent is and how many plants you want to grow inside of it. As a rule of thumb, you will need at least 2 x 2 feet of space per plant.

Now, this is pushing it a bit, as larger plants may need closer to 3 x 3 feet. So, if we are going with the 2 x 2 foot estimate, a single 2 x 2 foot grow tent could house a single plant.

Or, if you want to grow 4 plants, based on this minimum, a 4 x 4 foot grow tent could fit 4 plants, or 3 if they are really big.

A 6 x 6 foot is what we personally like, here is a good article we covered on just how many plants you can fit in them.

2. Ease of Assembly

The next purchasing factor that you need to keep in mind is the ease of assembly of the grow tent in question. The good thing about almost all grow tents is that they already come assembled.

You more or less have to just unfold them and pop them open. However, there are some larger grow tents out there where you have to connect the walls, the floor, and the roof using a system of zippers.

Generally speaking, these things are not hard to assemble either way, but the easier the better.

3. The Interior Lining

The next thing to pay attention to before making a purchase is what the interior lining of the grow tent in question looks like. Now, they will mostly all just be made out of some kind of reflective silver materials.

However, what you need to pay attention to here is how straight and smooth the lining is. You want the lining to be as smooth and flat as possible for maximum efficiency.

Second, you also want this lining to be fairly thick. There are some grow tents out there which have only a thin lining of this reflective material, and if you touch it the wrong way, or hit it with something sharp, it could rip, which obviously you don’t want.

4. Ventilation Holes

Something you also want to look for in a good grow tent is what kind of ventilation holes it has. First off, they should be well sealed and come with a zipper panel.

This way, in case you do not want to use the ventilation holes for some reason, you can keep them shut with an airtight seal. Second, you want to pay attention to the positioning of these ventilation holes.

Some grow tents will have 1, 2, 3, or 4 ventilation holes, and they can be at the top and/or bottom of the grow tent. The best way to go is with a grow tent that has 2 ventilation holes, with one at the top and one at the bottom.

The bottom will usually be used for air intake and the top for an exhaust system. Whatever the case may be, if you are going to get real tubing or a carbon filter, make sure that the fan, filter, intake/outtake tubing can fit into the ventilation holes (we have covered a buyers guide for Carbon filters here).

Your tubing and ventilation should be able to just fit into the hole without too much space in between. You do want an airtight seal here, so this is important to keep in mind.

5. Materials

Simply put, you want all of the materials which your grow tent is made with to be very durable.

Grow tents are usually made of either polyester or nylon, with nylon usually being the go to choice as it is more durable than polyester.

6. Racks, Hangers, & Fixtures

The final thing that you want to look out for here is the number and type of fixtures which the grow tent in question can handle.

There should be a number of hooks, clips, or other fasteners for you to attach lights, fans, vents, and screens to.

These can come in different configurations, but as long as you get something which can accommodate your equipment, you should be fine.


Alright folks, there you have it, a grow tent is used for growing weed and other plants indoors year round. They come with a whole lot of benefits, and while they might cost a bit to purchase, they are well worth the money when you consider the number of benefits they come with and how much of a difference they make in terms of the final product.
