What is a Grow Tent?
In basic terms, a grow tent is a tent used specifically to grow plants in.
"But can't you use any tent to grow plants in?" Yes you can. However, what sets indoor grow tents apart from other plant coverings- say, a green house- are that it's optimized for growing plants indoors.
This is largely in part because of their frames and their covers:
- Grow tent frames are made to withstand at least 100 lbs of weight. Grow tent frames are made to hold lots of weight to ensure lighting and other growing equipment can hang safely above plants.
Grow tent covers have a dual function. The exterior cloth is designed to prevent light from leaking while keeping your growing area insulated. The walls, ceiling, and floors inside are lined with mylar film to reflect light onto your plants for optimal lighting.
- They're also outfitted with ventilation ports for duct fans and carbon filters for optimal airflow and ventilation. Most grow tents also come with passive vent ports that allow air to freely travel in and out for even fresher air in their grow rooms.
Why Use a Grow Tent?
Setting up a grow room can be costly, and unless you're a contractor there's no guarantee your home will be ready for a grow room. That's why grow tents are the best option for growers, whether you're used to indoor growing or you're an outdoor grower.
But aside from avoiding a costly building fee, there are 5 great reasons you should use a grow tent:
✓ Reliable, Stable Growing Environment- Growing outdoors can lead to unstable growing conditions that can throw growth off. In a grow tent, however, you have the ability to dial in your plant's specific needs and keep them at optimal levels. From light cycles to temperatures and environmental conditions, growing in a tent will give plants a stable environment to thrive in, ensuring maximum results.
✓ Grow in the Space You're Already Using- If you're in an apartment or a home without a yard, growing plants outdoors is nearly impossible. That's what makes grow tents so great: you don't need an outdoor space to grow plants. Just set up a grow tent, use the right grow room equipment, and your room has a whole garden tucked away.
✓ Avoid Building an Entire Grow Room- Converting a bedroom into a grow room cost more money than using a grow tent, especially for renters that need to repair any alterations to their home. However, with a grow tent you don't have to anchor hooks for grow equipment or tack reflective material on your walls. They come with everything to provide the best environment to grow in, all you need are the plants and your favorite grow gear to get started.
✓ Portability and Mobility- Grow tents give you a mobile grow room. With breakdown and setup way easier than an entire room, you can make changes to your growing area when you see fit. So whether you're moving from one place to another, or you find a more optimal area on your home to grow in, a grow tent can be easily moved wherever it need be.
✓ Plant Protection- If you've got unwanted visitors poking around your garden, a grow tent is a great way to keep them out. With walls blocking views from outside and the ability to use carbon filters to block smell, you can keep your indoor garden safe from neighbors, pets, and pests. So whether you're doing more covert growing or pest control to avoid turning your plants into a bug buffet, a tent is the best way to assure your plants stay safe.
Which Grow Tent is the Best Size for Your Plants?
There's a grow tent for every grower out there, but you've probably noticed that there are tons of sizes to pick from. So we broke down your options into four categories to help you find the best size for your needs:
Small Grow Tents
✓ Perfect for Compact Growing- If you're growing clones or seedlings, or you have 1-2 mature plants, these tents will give you the environment they need to thrive.
✓ Best Tent for Hobbyist and First Time Growers- These tents are the perfect size for new growers and growers who like to grow every so-often because they can be easily tucked away.
Medium Grow Tents
✓ Great for All Growers- From beginners to pro's, these tents offer enough room to grow up to 5 mature plants. That means good yields for novice growers and great yields for advanced growers.
✓ Make the Most out of a Single Grow Light- These tents are the perfect to run a single 250w-1000w grow light for optimal growth. Whereas larger tents need multiple lights.
Large Grow Tents
✓ Huge Yield Potential- With the ability to house up to 8 mature plants or 4 trained plant, these grow tents have the ability to yield 50-100% larger harvests than smaller tents.
✓ Maximum Light Coverage- With 32-36 sqft of room to cover, you can use multiple high powered lights for even stronger growth. Increase intensity will create more flavorful harvests.
Extra Large Grow Tents
Extra Large grow tents are 10x5ft and larger.
✓ Perfect for Warehouse Growing- If you want to push your yields further, these tents can house well over 12 plants. Moreover, they can utilize 4+ grow lights for maximum grow light penetration and coverage.

What do growers have to save about GrowAce Grow Tents?
⭐⭐⭐⭐⭐ “Best Investment I have made” - Jim A.
As a first time grower, I was kind of obsessive with everything I needed for my grow. After looking at other brands, GGT was hands down the best I could find. The construction is amazing, the weight of the material blew me away. This tent is going to last a very long time, and well worth the price.
I kind of thought the 5x5 would be too large, but on setting it up, it's perfect. Lots of room for the plants without crowding. This beast is also light tight, no pinholes or gaps. Every detail looks to be well thought out.
⭐⭐⭐⭐⭐ “More than enough for the money” - Gordon M.
Who would have thought you get all these amazing features on a budget tent? The materials are solid and inner lining is reflective, it has viewing windows, Velcro straps, and water proof! I have harvested excellent yields in the past year using this tent and I'm never looking back! Thanks GrowAce!
"You just outdid yourselves with this Yield Lab tent!" -Sonny W.
⭐⭐⭐⭐⭐ “You just outdid yourselves with this Yield Lab tent!” - Sonny W.
GrowAce, I can't compare yours to the more expensive brands out there. Pound for pound, features and the quality of this tent is the best! I've had excellent yields using this tent and I couldn't be more happier!
⭐⭐⭐⭐⭐ “Easy to assemble and use” - Jeff S.
Tent was easy to put together. The tent will fit tight on the frame so work the corners a little at a time until they fit tight in the corners of your tent. It took me 35 minutes an one cup of coffee to put it together. Happy growing.
⭐⭐⭐⭐⭐ “Should've gone with Yield Lab sooner...” - Ryan B.
Not my first tent but it looks like it will be my last! Really well built and no more sway when loaded with my equipment like my last two tents. Wish I bought Yield Lab first and didn't waste my money on my other tents. This is the last tent I'll need.
Choosing the Best Grow Tent For Your Plants
Grow rooms are great, but an indoor grow tent gives you better control over your indoor garden. And aside from giving you more a controlled environment to grow in, a tent opens up growing to a whole group of people who don't have access to yards.
The only tricky thing about them is finding the right one for you. But when you take a look the features we've highlighted in this guide, you'll be able to find the exact grow tent your plants need.
Remember: there's a grow tent available in virtually any size for any type of grower. Just take the lessons you've learned here, find the tent you need, and start growing the harvests of your dreams.
Frequently Asked Questions
Q: What's the best grow tent to use?
A: The best grow tent to use is the one that safely houses your plants, prevents air and light leaks, optimizes light, and has the strength to hold your growing equipment.
As you can tell, all the tents on our list check all of those boxes. So how are you supposed to choose the best one?
When your options hit all the marks, the last thing to do is choose the best size for your plants. So here's a quick rundown of the most common sizes and how many plants fit in each:
- 2x4ft tents can house 1-3 mature plants
- 4x4ft tents can house 3-4 mature plants
- 5x5ft tents can house 4-5 mature plants
- 6x6ft tents can house 5-6 mature plants
- 7x7ft tents can house 6-7 mature plants
- 8x4ft tents can house up to 8 mature plants
Q: Where do I set up a grow tent in my home?
A: There are two important factors in figuring out the best placement of your grow tent: access to electricity and access to airflow. No matter if you're in a basement, a bedroom, or an attic, if the area has these two elements you're off to a good start.
- Electric Accessibility- Most homes have 15 amp breakers that can handle 1800-2000w of power. So when it comes to electricity you'll need to ensure your growing area has large enough breakers for all of your equipment. That includes your grow light ballast, fans, and any other equipment that draws energy. To figure how much you'll be using, simply look at the wattage draw of each piece of equipment you plan on running and add them together.
- Airflow Accessibility- While not absolutely necessary, windows in the room you're using will help bring in fresh air for your plants. Without a window, you run the risk of circulating stale air throughout your grow. So when possible, it's best to set up a grow tent in a room with windows.
Q: How hard is it to set up a grow tent?
A: Grow tents are simple to set up! Even at their largest, construction is as simple as connecting poles together and laying the cover.
While larger tents may be require more hands, grow tents don't require special tools or skills. If you've got the time and the space, setting up a grow tent is simple.
And once it's all set up, all you have to is install your lights and ventilation. In fact, to show you have easy setting up a grow tent can be, check out our setup guides below:
Grow Tent Assembly
Setting up a Grow Tent
Q: Can a grow tent be used outside?
A: Technically, a grow tent can be used anywhere to grow plants, including outdoors. But the reason grow tents were invented was to eliminate your reliance on outdoor conditions.
Unfortunately, outdoor conditions like heat will make the environment in a grow tent hard to regulate. And that's not mentioning the strain rain and wind will put on your tent and the equipment inside. Moreover, to light and ventilate a grow tent takes a good amount of energy, which means you'll need to string lots of cords out to your grow tent.
All seems like a bit much to do just to use a grow tent, doesn't it? It is. That's why we recommend only using grow tents indoors as intended.
Q: Are grow tents smell proof?
A: Grow tents aren't inherently smell-proof, as most have passive airports that allows air to travel freely in and out of the tent. However, they can prevent odors from creeping into the rest of your home by using a carbon filter and an exhaust fan.
- An exhaust fan pulls the air inside your grow tent- which contains odors, stale air, and unwanted particles- and pushes it away from your garden.
- That air is then sent through a carbon filter where odor and other particles adhere to the charcoal medium inside.
- When air leaves the filter, the air is odor-free.
So while grow tents may not be smell-proof, there's an easy way to make sure what goes on inside your grow stays between you and your plants.
Q: How many grow lights can I use in a grow tent?
A: The rule of thumb for grow lights is to have no more than 8 plants under a single light. That means most tents only need one light for your plants to thrive under.
But this rule doesn't account for large coverage areas, nor does it account for PAR or intensity that your plants need to thrive. So in order to find the right number of grow lights for your grow tent, it's important to consider the size (i.e. wattage) of those lights, too.
Here's a quick cheat sheet of grow tent sizes and their optimal lighting:
- 2x2ft - 3x3ft grow tents thrive with 1x 50-250w grow lights with a max PAR of 455 PPFD
- 2x4ft and 4x4ft grow tents can thrive with 1x 400w grow light with a max PAR of 650 PPFD
- 5x5ft grow tents can thrive with 1x 600w grow light with a max PAR of 900 PPFD
- 6x6ft grow tents can thrive with 1x 1000w grow light with a max PAR of 1377 PPFD
For large tents like 8x4ft or 10x10ft will want to use 2x or more lights. Most times, 600w or 1000w lights are used for optimal lighting. However, it's not uncommon to add more lower-wattage lights to give you a large, soft but affect light footprint for your plants.
So to figure out what it's vital to consider what PAR your plants need. From there you'll want to figure out which light(s) give you that PAR, and how many lights you need to achieve your grow goals.
Q: How do I regulate the temperature and humidity in my grow tent?
A: The environment inside your grow tent is regulated by your ventilation system. So when regulating the temperature and humidity levels in your grow tent, just configure your fans to maintain optimal conditions.
While plants have varying environmental requirements, maintain those conditions is the same in any grow room are the same:
If you're not doing so already, invest in a timer or a controller. These will regulate when your fans run instead of running them 24/7 or guestimating run times.
- To lower temperatures, increase the speed of intake fans to bring in air and exhaust fans to push air out quickly.
This will also lower your humidity levels, so be careful you're not getting rid of too much air and moisture.
- To raise temperatures, reduce the speed of your fans so that warm air stays in your growing area longer.
- Doing this will also raise humidity levels, so make sure your fans are able to get enough air and moisture out of your grow tent before things get too sticky.
Q: Are there warranties on grow tents?
A: Absolutely! All Yield Lab grow tents come with an industry-leading 3 year warranty against manufacturer defects. Secret Jardin and Gorilla grow tents come with a minimum 1-year warranty. Just contact us and we'll get your replacement part(s) shipped to you ASAP so you're up and growing quickly.
