If you’ve got limited grow space at home but aren’t letting that stop you, you’ll need to pick up a grow tent.

Marijuana grow tents are vital for indoor growing, but there are many grow tent manufacturers to choose from. If you’re having trouble picking a tent, don’t worry!

I’ve selected some of the best grow tents on the market to help you get your operation (and plants) off the ground.

What Is a Grow Tent?

Grow Tent

A grow tent or grow tent kit is essential for growing weed indoors. It’s essentially a portable enclosed space designed for growing plants, whether you’re cultivating cannabis, herbs, or vegetables for your salad.

Grow tents help you maximize your space and set up an operation in a spare room without having to pay for drastic renovations. They also offer privacy so you can keep your plants under wraps.

Grow tents also come in multiple sizes, ranging from 2’x2′ to 8’x16′ and larger, but I’ll mostly be covering smaller grow tents.

Regardless of the size you’re looking at, a high-quality grow tent will help you keep producing cannabis year-round, thanks to the controlled environment.

Whether starting an indoor garden or growing cannabis, a grow tent will help you maximize your space and grow more efficiently. Check out our guide on what grow tents are if you want to learn more about this handy indoor wonder.

The Top 8 Best Grow Tents on the Market

Here are some of the best marijuana grow tents you can pick up, arranged by size!

Best 2’x’2′ Grow Tents

I’ll start with the smallest tent you can get, the humble 2’x2′ tent.

1) Best Overall 2’x’2 Tent – Mars HYDRO Grow Tent

Mars HYDRO Grow Tent
  • Dimensions: 2’x2’x5′
  • Weight: 34.1 lbs.
  • Brand: Mars HYDRO
  • Where to Buy:

With this cannabis grow tent, you won’t need to look at other tents. That’s because this is a full grow kit with carbon filters and a grow light included.

That also explains this grow tent’s price! Most other Mars Hydro grow tents I’ve seen are usually more affordable, but this 2’x’2′ grow tent has everything you’ll need to start growing weed.

One of my favorite features about this grow tent is its velcro-lined observation window. Instead of being another source of light leaks, it’s easily sealed and opened as needed.

Mars Hydro says this grow tent can handle a weight capacity of 40 kg, but I’m not sure about that. The poles were hollow, but they should handle your fans and growing lights fine.

This isn’t the tallest tent you can get at 5′, so you might have issues maneuvering inside. Learn more about this grow tent in our Mars Hydro grow tent review.

2) Gorilla Grow Tent Lite

 Gorilla Grow Tent Lite
  • Dimensions: 2’x2.5’x5.7′
  • Weight: 17.36 lbs.
  • Brand: Gorilla Grow
  • Where to Buy:

The Gorilla Grow tent Lite Line gives you the same exceptional quality as other Gorilla grow tents but in a smaller (and lighter) package!

GG’s Lite line is more affordable than other Gorilla Grow tents, so this tent is ideal if you’re on a budget. However, I noticed that they made the fabric slightly thinner for their Lite grow tents.

This grow tent is 210D instead of the 1680D of a standard Gorilla Grow tent, which explains why it’s more affordable. Fortunately, Gorilla Grow kept their signature steel poles for the frame.

My grow lights were also working at peak efficiency thanks to this tent’s heavy-duty zipper and velcro flaps, which are common points of failure in grow tents.This Gorilla Grow tent has great zippers and top-tier ducting ports, excellent for keeping humidity in. However, I also recommend learning to control the humidity in your grow tent.

  • Velcro flaps for light-proof zippers
  • Height extension kit for taller strains
  • Removable spill tray for easy clean-up

  • Lacks an infrared-lined roof

3) CoolGrows Mylar Hydroponic Grow Tent

CoolGrows Mylar Hydroponic
  • Dimensions: 3’x2’x4.4′
  • Weight: 10.06 lbs.
  • Brand: CoolGrows
  • Where to Buy:

If you don’t have the budget for 2 grow tents, then CoolGrows is for you! This CoolGrows tent has 2 separate chambers for both flowering plants and plants in the vegetative state.

CoolGrows has also addressed the issue of viewing windows potentially harming your plants by tinting theirs in a chlorophyll-green shade, which is a nice touch.

I’m also a fan of the 600D frame cover. It’s a good thickness, so it should be fairly tear-proof, but I’d advise against slashing your grow tent to test it.

Clean-up is also easy with this grow tent since each compartment has a waterproof removable floor tray. The double-compartment design of this grow tent helped me speed up my harvest!

I did notice some slight leaks within the tent, but nothing drastic enough to affect my plants. Plus, they were easily fixable with duct tape anyway.

4) iPower Grow Tent 2.7’x2.7.’

iPower Grow Tent
  • Dimensions: 2.7’x2.7’x5.25′
  • Weight: 16.87 lbs.
  • Brand: iPower
  • Where to Buy:

Coming up next are iPower’s grow tents! These grow tents have a cover with 400D thickness, which is lower than I’d like, but it feels surprisingly sturdy.

You can get an iPower grow tent in various sizes from 2’x2′ to a massive 10’x10′, but I prefer their smaller grow tents for smaller batches of weed.

I also prefer smaller iPower tents because their frames are only rated for 110 lbs. This becomes a bigger issue when using larger grow tents since you’ll need more equipment.

iPower’s grow tents are fairly no-frills and affordable compared to the other tents I’ve covered. They’re packed with the essentials, they don’t stand out, but they’re solid quality!

  • Rust-resistant frame
  • Easy to assemble
  • Plastic-covered viewing windows

5) Best Overall 3’x3′ Tent – Spider Farmer Pro Grade Grow Tent

Spider Farmer Pro Grade
  • Dimensions: 3’x3’x6′
  • Weight: 18.56 lbs.
  • Brand: Spider Farmer
  • Where to Buy:

Spider Farmer sells everything you need to grow weed, and this grow tent is one of their finest grow tents. You can pick up a bundle on this grow tent with a grow light.

This’ll help you save money, but I’ve got to warn you: Spider Farmer’s lights are strong! I strongly suggest getting grow glasses, so you don’t hurt your eyes with this grow tent.

Its tool-free construction made assembling it a breeze. All I had to do was connect the metal poles, add the canvas and the floor tray, and I was done!

Initially, I wasn’t too impressed with the frame, but it held up to a few grow lights, so it’s probably strong enough to handle carbon filters.

This mylar hydroponic grow tent also has a top-class frame cover, making it thicker and more light-proof than other grow tents. If this sounds great and you want to know more, you can check out our full Spider Farmer grow tent review.

AC Infinity CLOUDLAB 733
  • Dimensions: 3’x3’x6′
  • Weight: 31.4 lbs.
  • Brand: AC Infinity
  • Where to Buy:

AC Infinity specializes in futuristic-looking grow tents. If you’ve ever looked at your tent and wondered, “Are there any subtler grow tents out there?” this tent’s for you!

Once I’d received my grow tent, I thought a mistake had been made. It looked more like a giant safe or cabinet than a tent, but the labels were clear.

I didn’t have any issues with my Cloudlab tent, but AC Infinity offers a 2-year warranty if you run into any problems and provides a return shipping label. Points for customer service!

This hydroponic grow tent has an excellently thick 2000D frame cover, even thicker than Gorilla grow tents. Thanks to the removable mylar floor tray, I also found it easy to clean.

Its thick canvas, great warranty, and sleek look make AC Infinity grow tents excellent and durable.

  • 2-year warranty from the manufacturer
  • Diamond-patterned reflective interior
  • Relatively heavy
  • Slight light leakage around the zippers

7) VIVOSUN S336 Grow Tent

  • Dimensions: 3’x3’x6′
  • Weight: 20.4 lbs.
  • Brand: VIVOSUN
  • Where to Buy:

VIVOSUN sets the standard for quality and affordability with its to grow tents. It’s like a marriage between durability and usability with their tents, which is why I’m a big fan of theirs.

With modest dimensions of 3×3 feet and a height of 6 feet, this is a comfortable medium-sized grow tent aimed at beginners or professionals who want a smaller growing space.

I recommend VIVOSUN for beginners because you know exactly what you’re getting with this tent: dependability. Its 600D canvas will do the job, and its removable floor tray is great for cleaning up accidental spills.

Their floor trays are also reflective, so you won’t have to worry about your grow lights being wasted on the floor. I spotted pin holes along the seams indicating light leaks, but it wasn’t bad enough to affect my plants.

This dependability is what makes VIVOSUN a popular choice among growers. VIVOSUN grow tents are great whether you’re a beginner or a veteran grower.

TopoGrow 3'x3'
  • Dimensions: 3’x3’x6′
  • Weight: 19.46 lbs.
  • Brand: TopoGrow
  • Where to Buy:

Rounding out my picks is TopoGrow’s 3’x3′ grow tent, which I’d recommend for patient growers and pros. That’s because this grow tent lacks observation windows.

Unlike the tents I’ve covered above, you can’t repeatedly check on your cannabis from the outside. You’ll have to open the zipper to see how your plants grow.

I picked up this grow tent but only used it for a few harvests because I couldn’t stand being unable to see my plants whenever I wanted, but this style of grow tent helps with privacy.

Fortunately, this also meant I didn’t have trouble with the zippers or canvas, but TopoGrow equipped this tent with a tear-proof 600D canvas cover.

It also has many built-in ports, so you won’t have problems setting up your ducting.

  • A great built-in duct system
  • Corrosion-resistant frame
  • Industrial-strength zipper

Why Should You Use an Indoor Grow Tent?

Best Grow Tents for Cannabis

Grow tents are a vital part of small-scale cannabis cultivation, and it’s easy to see why. Here’s why you should use a tent for growing weed.

Control Your Marijuana Growing Environment

There are various cannabis strains you can grow, and they each have unique growing needs. Depending on which cannabis plant you’re cultivating, you’ll need to help them thrive within the tent.

The main benefit of using cannabis grow tents is controlling your marijuana’s growing environment. Instead of relying on your natural climate, you can make your own!

You can grow your marijuana plants faster within a cannabis grow tent with the help of a good LED lighting system. The best LED grow lights run cooler and use less energy than other lights!

Cannabis grow tents are an ideal growing space for your plants, but an ideal environment is more than just the space. You’ll also need to keep your grow tent cool for your plants.

Keep Your Cannabis Plants Protected

It’s important to create favorable growing conditions for your weed, whether you need to lower or raise the humidity. However, don’t let your cannabis grow tent get too humid!

Too much humidity can also invite pests and diseases like bud rot and powdery mildew to ruin your yield.

Remember to regularly inspect your plants for signs of mold and pests and take preventative steps like growing mold-resistant weed strains.

Grow tents are vital for growing cannabis plants indoors, but they’re not the only thing you need to consider.

You’ll need to add grow tent accessories like lights, humidifiers, and pots to create the perfect growing environment for your plants.

Offers Privacy

Like any other business, keeping your growing operation private is the best way to protect your investment.

Regardless of how many plants you have, they’ll be safer from prying eyes inside an indoor grow tent rather than growing right outside your home.

Grow tents are a great way to keep your cannabis plants private and protected but remember to keep your grow tent clean. A dirty tent can also invite pests and other problems!

Contains Smells

Another benefit of grow tents is their ability to keep the scent of your buds firmly inside instead of letting the whole neighborhood smell what you’re doing.

Cannabis seeds are almost odorless regardless of the strain, but the plants themselves give off terpenes, which can be stronger or weaker depending on what you’re cultivating.

As you may know, weed smells when smoked, but some strains also give off a strong scent when growing. You’ll understand the need for a tent once your cannabis plants bloom.Using the best inline fans, you can keep your tent well-ventilated and your plants healthy. Ensure your grow tent has enough space for it!

What Are Features to Look Out for When Choosing a High-Quality Grow Tent?

Cannabis in grow tent

Before taking your first steps into the grow tent market, here are a few things I recommend looking for. Try to tick as many of these features as possible to make your growing operation smoother.

Budding cannabis growers have several grow tent brands to choose from, offering similar features. Before springing for the first expensive tent you find, see if you can save money with a better deal!

Sufficient Floor Space

Even if your budget limits you to an average grow tent, you’ll still need to consider how many plants you’re cultivating and the space they’ll need.

Each plant will require ample space to mature and begin budding. As a rule of thumb, I suggest providing at least 1 sq. ft of space per cannabis plant in your grow tent.

This will ensure you’ve got enough clearance to move around your tent, whether you stuff it full of equipment.

Height Clearance

A standard grow tent should have a solid metal frame interlocking strong metal poles. However, what happens if you’re planting taller marijuana plants?

Some tent manufacturers have height extension kits for their grow tents, like Gorilla tents. This will help you quickly compensate as your plants grow taller without having to prune them.

You should also ensure your tent has enough height to hang lights or netting from the frame to provide your plants with a consistent height canopy.

I also recommend getting a tent that’s comfortable in height. You don’t want to make moving around your weed plants harder.

Remember that even if you pick up a tall tent kit, your growing tent’s pots will reduce your usable space. Get the right kind of pots to provide your plants with good drainage.

Ensure It’s Light-Proof

Since an indoor grow tent’s main function is to act as a controllable environment, you must ensure that your plants have a proper “nighttime.” This means getting a grow tent that’s free of light leaks.

Light leakage can cause your marijuana to revert to the vegetative stage, so avoid it at all costs by investing in a sturdy and well-sealed cannabis grow tent.

You can also avoid this issue by keeping the room or area around your tent in the dark. This way, you won’t have to worry about the light even if your tent has leaks.

Even if your tent has enough light and is well-sealed, you’ll still need to keep it warm to ensure the plant’s flowers. Remember to get a solid heating system for better yields.

Tough Fabric

Size and steel poles are a good start, but the best grow tents also need sturdy fabric. Ideally, your grow tent’s fabric should be a thick canvas stretched over the frame.

However, I’ll also add that your tent’s fabric must be tear-proof. A tent that’s 600D (denier) or higher should be enough to last you a while.

Turning to the interior, ensure your tent has a reflective mylar interior to keep light focused on your cannabis plants, ensuring better growth. This is vital to compete with sunlight.

Don’t neglect your grow tent’s ventilation, either; even if it’s made from strong canvas, you’ll need a reliable fan system to improve the air circulation within your grow tent.

Tough Zippers

Since they’re constantly in use, your grow tent’s zippers will likely be the first point of failure. Once your tent’s zippers fail, you invite all kinds of pests into your grow tent to have a snack.

Zippers are also a source of light leakage since they’re large gaps in the sides of your grow tent. You can light-proof your tent with strips of tape or add an extra reflective lining for the interior.

If you think your grow tent has light leaks, enter the tent and turn off all the grow lights. Any leaks should be visible as dots of light against the grow tent’s pitch-black mylar interior.

Apply duct tape as needed to keep light from escaping your tent, and ensure your grow lights are working at peak efficiency.

Room for Ports and Windows

After setting up your growing medium, floor trays, and grow lights, you’re not finished yet! A good grow tent needs space for air filters and ventilation.

Ensure that your chosen model has adequate ventilation ports and space. You don’t want to get a tent only to find out that it’s virtually impossible to set up the ventilation.

Once your cannabis starts blooming, you’re at risk of inhaling spores and impurities that could harm your lungs. A carbon filter is a solution to that problem!

Ensure your tent has room for a high-quality carbon filter for your own safety.

Next, it’s important to ensure your grow tent has light-proof viewing windows. These are vital so you can observe your plants without disturbing them.

Excessive changes in light and temperature can stunt their growth or even kill them, so I recommend getting a grow tent with an observation window.

Frequently Asked Questions (FAQs)

I’ve got answers if you’ve more questions about grow tent kits!

How Big of a Grow Tent Do I Need for Cannabis?

Cannabis plant

Before choosing a strain of cannabis to plant, it’s vital to pick the right size for your set-up. As a general rule, it’s recommended that you prioritize height over square footage.

Hobbyist cannabis growers should look at grow tents that are 6′-7′ at minimum. This is important so your plants have enough clearance to grow taller without hitting the grow light.

Your tent should also have a floor space of at least 2 x 4 feet because this size is perfect for 1-2 plants. A 4×4 tent may be more cost-effective despite being slightly larger.

What Is the Best Grow Tent for 6 Cannabis Plants?

Marijuana plants can reach 30 feet in height, so you’ll need plenty of clearance. But that depends on the strain you’re cultivating and whether they’re sativa or indica.

But if you’ve settled on cultivating 6 plants, regardless of the size, your best bet would be checking out VIVOSUN grow tents like the S558 or S336 models.

These grow tents can comfortably fit 6 plants and are outfitted with heavy-duty zippers that’ll last a long time. VIVOSUN also offers 4×4 feet grow tents, which can hold even more plants.

Does Cannabis Need a Grow Tent?


Strictly speaking, you don’t need a grow tent if you have enough outdoor space and a favorable environment. However, it’s very useful if you want to grow cannabis indoors.

Cannabis is a weed, so it’s tough and will grow regardless of whether it’s outdoors or in a tent. But to encourage better and more controlled plant growth, you’ll need gear like humidifiers and a tent.

It’s also more cost-effective if you can’t renovate an entire room for your growing needs. Grow tents are also worth investing in for added privacy!
