Best Small Grow Tents: A Complete Buying Guide for Users

Cultivating plants doesn’t just take skill — it’s an investment too. Unfortunately, not everyone has the perfect environment for growing plants.

Enter small grow tents!

These allow anyone to grow cannabis plants indoors, even with limited square footage!

In this article, I’ve compiled the best small grow tents and a quick guide to choosing the right one for you.

7 Best Small Grow Tents

Below are my most highly-recommended small grow tents for your indoor growing of cannabis plants:

1) Vivosun S223 2×2 Grow Tent – Best Overall

Vivosun is a BIG name among grow tent manufacturers. This model is a high-quality indoor grow tent that’s less than three feet on each side.

Its outer material is made from tear-proof and double-stitched 600D oxford canvas. This ensures that it won’t experience light leaks.

Meanwhile, the inner lining is made with 100% reflective diamond Mylar so that all the light gets reflected back to your plants!

This Vivosun grow tent also offers many openings for equipment — such as for duct fans, lamps, and electrical cords.

You even get an inner tool bag and a removable waterproof floor tray.

The door unzips across three sides, which made it quite tricky to open when I placed it in the

2) GreenHouser 24″X24″X48″ High Reflective Grow Tent – Best Value

GreenHouser offers a good tent for its price.

The inside is made of 96% highly reflective waterproof diamond Mylar. The mid is PVC-free, so it’s non-toxic and environment-friendly.

The outer is made of a strong 600D oxford cloth. This, together with the heavy-duty zippers and double stitching, means you get light leak protection.

What’s interesting about this GreenHouser grow tent is that it has meshed vents for better ventilation.

However, I noticed that it DOESN’T have an observation window — so I had to open the door to check on the plants. This can possibly disrupt the controlled environment.

3) CoolGrows 24″x24″x36″ Grow Tent – Best Budget

CoolGrow’s tent is quite impressive despite being a budget pick.

Its inner Mylar returns 93-97% of the light that hits it. The polyester material for the outside is also very durable and tear-proof.

The whole thing is lightproof. However, I’ve seen some customers complain about noticing a few pinholes in the stitching.

You can take care of that by using black appliance touch-up paint.

What interested me the most about this tent is that the front window filters out white light. This further protects your plants from light disturbance.

The tent has dual-cinching duct ports to make it EASY to seal light and air around ducting and cords.

4) AC Infinity Advance Grow System 2×2 – Best Smart Grow Tent

Having a grow tent doesn’t automatically mean you can cultivate plants. After all, you’ll need to control things like humidity and temperature.

If you’re like me and you’re having a hard time monitoring those factors, then AC Infinity has the PERFECT tent for you!

Unlike other tents, this particular model has the Advance Grow System that puts your indoor gardening on autopilot.

It has a smart climate control system that lets you customize schedules by automatically adjusting fan speed and brightness.

You can even set climate triggers and receive data graphs and other notifications through the Bluetooth app.

Of course, it’s also a COMPLETE kit that comes with programmable LEDs, a trellis net, and more.

However, I do admit it can be difficult to set up — not to mention all those inclusions and features that make it more expensive.

5) Spider Farmer 2x2x5ft Tent Kit with SF1000D Samsun Diodes – Best LED Grow Light

Spider Farmer offers another full kit containing the essentials — such as an inline fan, carbon filter, and flex aluminum ducting.

But I’ve put this grow tent on this list because it offers the best LED grow lights.

This model uses the Samsung LM301B diodes that allow for a full spectrum light — which makes it great for all stages of growth.

These LED grow lights also have a protective coating for a longer lifespan.

It has a powerful but quiet ventilation system too.

However, I’ve noticed that it’s not COMPLETELY lightproof.

For one, some of the seams allow for light penetration. Then, the mesh intake vents have a removable velcro cover.

I personally think it would have been better to have flaps since the removable cover might also cause some light to leak.

6) Gorilla Grow Tent Lite Line 2×4 – Best Height-Adjustable

Gorilla grow tents offer a height-adjustable option in case you need a taller tent later on. This makes it PERFECT for the whole growing process.

At its tallest, this grow tent can be a full foot taller. Unfortunately, the extension kit is sold separately.

The Gorilla grow tents in the lite line have the same pro features as their original line — at a lower price! The fabric is still durable but more lightweight.

You also get strong metal poles, tough zippers, and big viewing windows.

I found it really convenient that this model has a 360-degree Wrap Around Access so you can tend to your plants from ANY angle.

7) iPower 24″x24″x55″ Mylar Hydroponic Grow Tent – Best for Large Headroom

iPower’s model would be the tallest tent on this list — making it great if you have a high headroom.

The manufacturer is also well-known for its grow lights, so you’re sure you’re in good hands.

I appreciate how the observation window can be covered with a removable mylar sheet so you can cover it when not in use. This allows for as much light as possible to be reflected back.

However, I did notice that this grow tent tends to leak light around the zippers.

Why Should I Use a Grow Tent?

Grow tents help you create the IDEAL environment for raising high-quality cannabis.

Grow tents have reflective inner walls to spread the light from your grow lights. The materials also prevent light leaks.

Aside from lights, they also help contain the smell and humidity.

Having the right equipment lets you better fine-tune the environment inside the grow tent too.

A SMALL grow tent is much more convenient. After all, it has a small footprint! You can place it anywhere — even in closets. A small grow tent is also more portable.Another plus to small grow tents is that they use less energy since they can retain the heat inside more efficiently than large tents.

Factors to Consider When Choosing the Best Small Grow Tent


All grow tents act as an indoor greenhouse. However, there are several things to keep in mind to buy the right one for your needs:

1) Space

It’s a given that small tents will produce small plants.

But even if you’re keeping your plants small, they still need ENOUGH space to give you high-quality yield.

To help, you can check this guide on grow tent sizes for a basic idea of what you might need.

Aside from floor space and vertical space, you should also think of your equipment — such as lights and pots for grow tents.

2) Lighting

Indoor gardening cannabis plants rely on one of three types of lighting: HID, CFL, and LED.

HID (high-intensity discharge) lamps have been used since the 1990s. However, they’re hot and can burn your plants if they’re too close.

Because of that, they’re not good for small grow tents with a low height.

Fortunately, LED systems are slowly becoming a trend. They’re much cooler, making them safer to be closer to plants.

3) Sterilization

In an actual greenhouse, there are predators that can get rid of the pests for you. However, in a small grow tent, things can EASILY spiral out of control.

As such, see if you also have enough room to clean the inside from time to time.

Having a removable floor tray is really helpful for getting rid of standing water.

4) Ventilation

Plants NEED fresh air. As such, you’ll need a solid ventilation system to ensure that they get it. Check if your grow tent has room for the required equipment.

For one, an oscillating fan will help manage temperature and humidity in the grow room.

However, they’re not enough. To help, an inline fan will suck out the hot and humid air to let fresh air in.

To further help regulate humidity, it would also be a good idea to have a humidifier too. Depending on your lights and the temperature outside the tent, a heater or AC can help as well.

5) Material

Many tents also find light leakage a problem — so this should be something to watch out for.

Tent fabric tends to be made of a canvas-like material that has a reflective interior and can block out light.

Cheaper models typically use polyethylene, which does the work. However, they’re not tear-proof.

Higher-end tents use Mylar. This tent material is THICKER and more durable, providing better insulation and reflecting more light.

You should also check for a sturdy structure. This means opting for steel poles and metal frames.

Plastic corners (such as those used in the Secret Jardin Hydro Shoot tents) might make most tents relatively cheaper and lightweight.

However, they won’t give the same support as a FULL metal frame. Not to mention, it might crack from the weight of your equipment.

6) The Strain You Want to Grow

Indicas are best suited for small spaces. That’s because they’re short and stocky — only experiencing a 50 to 100% increase in height.

This means you can put them in small grow tents with low headroom.

You can also work with sativas, although you’ll need to spend more time and attention pruning them.

This is because sativas in the flowering phase can have a 200 to 300% increase in height. For these, I recommend you choose small grow tents with higher headroom.

Regardless of which strain you want to grow, consider your tent’s plant capacity to ensure that it can accommodate the plants.

Tips to Make the Most of Small Grow Tents

Grow tents are handy to have, whether you’re a beginner or an expert.

Below are a few tips for setting up your grow tent:

Plan Your Design First

Before you buy ANYTHING, it’s important to plan the layout of the room you’ll be putting the tent in and how the tent’s inside will look first.

Think of the factors I’ve listed above. What kinds of lights will you need? How can you ensure that the plants get enough fresh air?

It’s also better to plan to put the tent on top of concrete or tiled floor in case water accumulates on the ground.

Planning everything beforehand means that setting up can go as smoothly as possible.

Place the Tent Near an Electrical Outlet

It’s best to place the tent near an electrical outlet that can properly power your equipment.

This is also PRACTICAL since you won’t want people to stumble over cords — which can either accidentally unplug equipment or damage the cords.

Keep a Journal

Once you’re all set up, a garden journal can help you monitor environmental conditions (like humidity, temperature, and light) and record plant growth.

At first, recording these factors can be like trial and error as you look for the best conditions for your plants.

As you get used to it, recording these metrics will help you pay attention to when you’ll need to adjust certain things.

Frequently Asked Questions (FAQs)

Are Indoor Grow Tents Worth It?

Yes, indoor grow tents are VERY worth it. After all, you get to create the best environment to encourage vigorous growth.

If you have SMALL tents, then they’ll work very well in any space since they only have a small footprint

What Is the Best Size Grow Tent?

The best size grow tent depends on how many plants you want to cultivate.
