Choosing the Best Grow Tent

This is what it looks like when you choose the best grow tent. Choosing a grow tent is a big step, and there are many important considerations to take. You most likely want the grow tent to be nice and tough, with thick canvas and strong supports, reflective inside, and easily tightened air holes. The size is probably the main factor which will be different from person to person. Thankfully, grow tents come in all shapes and sizes.

Most of us will want to purchase a grow tent, as they provide the best scalability, and bang for your buck. You will be able to grow at least two plants in even the smallest tent, whereas a grow box is only good for one small plant.

There are also many different configurations within one category. Choosing the best grow tent for your situation requires thinking about where it’s going to go, how the ducting might be laid out, what kind of features you might want, and other things. 

Many people like to grow in their closets, or on shelves in a little grow box. It’s a great solution if you want a nice low key stealth setup. For that, you might want to consider a little grow box solution. There is something for everybody here! Let’s look through some important considerations in detail.

Grow Tents

Grow tents are usually 2×2 around, and usually at least 5 foot high, and upwards. A good place to start is a smaller tent which you can also progress forward in. For example, a 2×2 might be good for when you first begin, but once you get into wanting to grow 4 plants, it’s going to be impossible. Instead, I recommend that you choose at least a 3×3.

The height for a grow tent really depends on the kinds of plants you’re looking to grow. A lot of sativa plants grow tall and big regardless of training. On the other hand, if you’re going to use a scrog net – screen of green technique – or other training tactics to keep the plant short, height isn’t much of a concern.

For a full on grow tent, it’s recommended to be at least 5 feet tall. This might seem excessive, but you will want the clearance space between the light and the plant. You also want to have a decent amount of room to move the light up and down as the plant grows.

If you don’t have enough room for a 5 foot tall grow tent, you could get away with 4 foot, but only with the right technique. Use LED lights so that the plants won’t get burned by lights if they get too close. Also, use a scrog net or training techniques to keep the plant low. Planting Indica dominant strains will also result in nice little bushy plants, perfect for short enclosures.

3'x3'x6' CoolGrows Grow Tent

I think this is your best option in the low price range from Amazon. Not only is it $20 cheaper than the most popular VivoSun tent, but it also has a completely metal structure, and the fabric does usually seem to be a decent amount better. The 36x36x72 inch volume makes it a great setup for a small room. This gives you enough space to experiment with new setups, multiple different varieties of plants – whatever your imagination desires. Alternatively, they also offer 2 ft x 2 ft and other size tents on the same page.

What Makes the Best Grow Tent?

Although on the surface, all these tents look basically the same, there are really big differences in real life. I mean, all a grow tent or grow box really is, is a black exterior with a shiny interior, a few metal poles around the sides to make a skeleton. The build quality is obviously different throughout the market, but there are also other important differences. 

Some offer more structural support, different configurations for the ducting holes, removable floor pans, see-through plastic windows.  Not to mention, they all come in different sizes, not only in terms of floor area but also height. The tents go from 3 feet to 6 or 7, and anything underneath is classified as a grow box. 

Let’s go through some of these things and how they might impact your decision making.

Ducting Holes

The holes are probably one of the most important things to consider. This is something I did not think about when choosing either of my tents, only to be met with situations where I could have used them later. For example, I could have used an inlet and outlet from the top rather than just an inlet in one particular situation.
In another situation, I wanted to have ducting on both sides at the bottom. Therefore, in order to start choosing the best grow tent, you’re going to need to plan out the duct fitting locations. Generally, you only need one duct hole at the top for your outlet, but an inlet is nice too. Also, I’ve hooked multiple tents together with the bottom holes. Some of them – usually the small ones at the very back, middle – are used for electric wires.

In addition to location, there is also the question of air tightness. Some of the really nice tents feature two layers of sealing action around the ventilation fittings rather than just one. Also, some of these seals are made with better stitching, and better fabric. All of this adds to the air tightness of a tent, which is important in maintaining proper air flow. 

Multi-Chamber Grow Tents

4'x3'x6' TopoGrow 2-in-1 Grow Tent

This is a fantastic two in one tent solution. It is a small profile – 4 x 3 x 6 feet, but it’s got such a great versatility. The whole structure – both the left and right portion of the tent – is completely made of metal. There are so many vent holes placed everywhere, allowing for endless configuration. You should buy this if you know you want to go hard on this growing life. I wish I bought this earlier, to be honest, because it provides a perfect little spot to clone, propagate, and carry plants through flower – all at the same time! It’s a powerful little package I would recommend. 

Some of the best grow tents feature multiple chambers. This is a great option if you are looking to grow in perpetual cycles. You can grow plants for a month and a half or so in the small chambers, and grow them fully in the big one, keeping a constant cycle going. This is very efficient, and I would recommend thinking about this option if you know you want to get serious.

These chambers can be set up in different ways. Some of the smaller chambers can be multi-tiered, so you can fit two layers of small veg state plants in one side of it. This is a powerful option, and once you transfer it over into the main chamber with the big light, they usually just explode.


Although most of the frame clips are plastic across the brands, they are not of the same quality. Also, there are a few really good grow tents which feature a full-metal structure. However, the ones I have bought are put together with plastic. 

I’ve noticed that the higher price ones are reinforced, and are designed to be very structurally rigid. Also, the better tents will provide multiple cross-members for the top rather than just one, keeping the whole thing stable. I’ve had my cheap tent for a few years and it’s quite unstable – moves quite a bit upon opening and closing. 

Other Features

Other features you might want to consider having is a grow window. This might be interesting, but I don’t have one and it hasn’t been much of a problem. I suppose if you like the idea or don’t want to open the door and disturb the environment, this might be a good idea.
Some tents come with little pop-out trays, but I honestly think that’s kind of a gimmick. They are usually made like garbage, and if you’re serious you’ll get real trays for every 2-4 plants anyways.

Grow Boxes

There are the little grow boxes, which are fantastic for either propagating clones, or growing plants for the first month and a half of vegetation. You can carry a plant through to maturity in a grow box, but it does take a bit of training, so that the plant stays controlled. 

This solution is great for those who want a super stealth solution, or a very energy efficient solution, or just don’t have the space for a big setup. All these things are well and good, and I think if these things are important to you, try out a grow box. 

2'x2'x3' CoolGrows Grow Box

This is a cute and nifty little box, one of the best ones I can find, especially for this price point. All metal skeleton, fits in any closet, fits around two tents, maybe three if you go with small pots. It’s got plenty of holes for the size, a nice big observation window, and a nice thick sheathing. If you’re looking for a mean little box to grow in, this is it. Outfit it with a cool little LED array, and a 4″ blower fan, around 100 CFM is fine even, and you will have yourself a dope box, literally. 

It’s going to be a little bit hard to grow a full plant in there, try growing super bushy auto-flowering strains. Indica dominant autos are pretty good in grow tents. They mature very quickly, stay low, and usually still product some pretty sticky icky nuggets. If you’re looking to grow a few ounces every cycle, a grow box is perfect, but get the right genetics!

So, if you’re looking for a little grow box for propagation, you could go for a 2x2x2 box. Alternatively, if you’re looking to grow some auto flowers for example, or smaller plants, you can go with a 2x2x5. Both models would easily fit into a little closet, which is very appealing for many beginner growers. Just be sure that you have adequate ventilation, especially if you are using a little HID – High Intensity Discharge – light bulb, as those get hot quick.
