Trying to nurture young plants can be a delicate business. The wrong temperature, not enough moisture, too little light – and before you know it, they’ve withered and died.
Here, we take a look at some of the best indoor grow tents to give them a helping hand. And we explore the factors to consider when choosing the right one for your plants.
At a glance: Our Top 5 Picks for Indoor Grow Tent
The Best Indoor Grow Tent of 2019
1. TopoGrow 2-In-1 Indoor Grow Tent
If you’re looking for a grow tent to support your plants at various stages, TopoGrow’s tiered option is worth considering.
One side of the tent is divided horizontally with two shelves, perfect for propagating seedlings. The other side is full height, with plenty of space for more mature plants to grow and bloom.
The design is flexible too. If you prefer, you can remove the central divider and shelf to create more space for bigger plants.
The frame here is made completely of steel – and that includes the corner pieces. It makes it very sturdy and durable. There’s also a metal support beam from which to hang equipment such as a light, inline fan or carbon filter.
The tent is a good size– six feet tall, four feet wide and three feet deep. TopoGrow also makes one smaller, and two larger versions.
The shell is made of 600D black Oxford cloth. It’s completely plain, so if you like a minimalist aesthetic it’s a good option.
Inside, the lining is diamond patterned Mylar, which TopoGrow say is 100% reflective.
There are vents for exhausting, secured with cords and toggles.
And there are mesh-covered Velcro pockets along the sides. These allow you to view the interior without opening the tent and affecting the growing environment. Unfortunately, though, there are no windows at the front. It’s not a deal-breaker, but they would have been a helpful addition.
Bear in mind that this tent will need a ventilation system capable of circulating air around both growing spaces. An easy way of dealing with this is by using a tee to split the air flow from your fan.
Take care, too, not to overload the hanging beam. Position your equipment so that it’s equidistant from the two hooks to avoid the risk of the whole thing collapsing.
- Handy dual chamber design supports plants at different stages of growth
- Flexible design can be adapted to meet changing needs
- All-steel construction makes this durable and robust
- No viewing windows at the front
- The hanging beam isn’t as strong as some others.
2. VIVOSUN 2-In-1 Mylar Reflective Grow Tent For Indoor Hydroponic Growing System (Our Top Recommended)
Another grow tent with two chambers, this one from Vivosun has a lot to recommend it.
The smaller chamber on the right acts as a nursery for younger plants. It’s divided completely from the left-hand chamber with a removable sheet of Mylar. That gives you the flexibility to create entirely different microclimates.
The right-hand chamber comes with a central shelf, allowing you to further subdivide the space. Put seed cones on the shelf to germinate, then move them to the bottom as they mature.
When your plants are bigger still, they can move into the left-hand chamber. It’s a design that gives you plenty of versatility. And if your needs change over time, you can remove the central divider altogether to create one big space.
A 600 watt LED grow light works best here, and a 4-inch inline carbon filter. Bear in mind too that if you’re using the central divider, you’ll need separate ventilation systems for each chamber.
It comes with three different floor trays. So whatever configuration you’re using, you’ll be able to keep the bottom of the tent clean.
The frame is made of metal and it’s good and sturdy. It’s easy to put together too – an averagely handy person will be able to complete it in about 20 minutes.
The outer shell is an extra-thick canvas. It won’t tear, and all the seams are double stitched to avoid pinprick holes letting in light. The Mylar interior will reflect 98% of the light back inside the tent.
There are a multitude of vents too. There are four round four-inch diameter vents, four that are six inches in diameter, and three rectangular mesh covered vents.
The tent also comes with a cute extra – a mesh fronted tool bag to store your bits and bobs.
The zippers here are a little stiff at first, but after a few uses, we’ve found they run smoothly enough.
If there’s one area where we think this could be improved, it’s the central divider. Because this is simply a sheet of Mylar, fixing it perfectly in position is tricky. If you want complete separation between the two chambers, you’ll need to spend a bit of time getting it right.
- Option to create multiple growing environments
- Good quality canvas and double-stitched seams retain 98% of light inside the tent
- Comes with three-floor trays and a handy tool bag
- Zippers can be a little stiff to operate at first
- Central divider is tricky to get perfectly in position.
3. TopoLite Full Range Multiple Sized Indoor Grow Tent
This indoor grow tent is more like your plants’ very own solarium.
The exterior is made of dark Oxford cloth. And it’s lined with Mylar coating with a diamond pattern that makes it highly reflective. The seams are well made, and the zippers have light-proof backing. The combination means you won’t have light leaks to worry about when you’ve installed your LEDs.
The frame is constructed of metal bars which fit together tightly, with reinforced plastic corner pieces. There’s no mention of whether the plastic is UV-resistant, however. If you choose this tent and want to guarantee a longer life, paint them with marine or auto polish.
The tent fits snugly over the frame, and the whole thing is sturdy enough to move around after assembly. It comes with an additional floor tray, which fits neatly in place. There are also two nylon belts which can be used as filter straps.
To help keep the air moving freely, there are a number of rectangular vents covered in mesh. There are also two large duct ports, which will fit any vent between 4 and 8 inches. They’re opened and closed with sturdy cords, with a toggle attached for ease of use.
A metal cross at the top of the tent is perfect for hanging a light.
The only downside here is that there aren’t any grommets to help with running in a water supply or power cord.
If you want to do that, you’ll need to insert them through the intake holes at the top or sides. Alternatively, you could cut your own holes – but you’ll need to use a sharp blade, so take care.
- Sturdy metal frame
- Well fitting cover with highly reflective lining
- Comes with additional floor tray and two nylon belts which can be used as filter straps.
- No grommets to help with running in power cables or water supply
- Unclear if the plastic corners are UV-resistant – paint them with paint or auto polish to make sure.
4. CoolGrows Small Indoor Mylar Hydroponics Grow Tent
This is the smallest of five indoor grow tents produced by CoolGrows. It’s four feet tall by two feet wide and two feet deep. Those compact dimensions make it a good choice for any indoor gardeners short on space.
It’s a smart looking tent, too, with the CoolGrows logo emblazoned on the top right-hand corner.
The shell is the usual combination of tough 600D Oxford fabric and highly reflective Mylar interior. It fits snugly over the steel frame, without pulling or wrinkling. The snug fit does mean it can be a bit tricky to get into place, but it’s worth the effort.
Both the bars and connectors making up the frame are made of metal. They click together easily, and assembling the whole thing takes no more than half an hour. You won’t need any tools to do the job either.
There are plenty of vents here to keep the air flowing freely. Each side has a vent on the top and bottom, and there’s one on the uppermost surface too.
There’s a well-positioned viewing window at the front, secured in place with Velcro. Use it to check on your plants without interfering with their growing conditions. Just make sure that you position the cover in place carefully when you’ve finished to avoid light leaking out around the edges.
The removable floor tray makes cleaning easy. It will collect any drips, dead leaves or loose soil. Just take it out when it gets dirty, and give it a rinse.
The tent also comes with two nylon hanging straps, both of which are secured with plastic buckles. The zippers are backed with privacy strips to avoid light leaking through. The fabric isn’t the thickest, though, so they will stick from time to time.
A perennial problem with less expensive grow tents is that they often let in pinpricks of light. This is also the case here. On the plus side, CoolGrows have anticipated this problem and included an extra strip of Mylar for patching.
- Solid metal frame
- Well-positioned viewing window
- Removable drip tray makes cleaning easy
- You may find you need to cover up pin prick holes – extra Mylar is included to do the job
- The zippers aren’t the smoothest.
5. OPULENT SYSTEMS Hydroponic Mylar Water-Resister Grow Tent
This single chamber grow tent from Opulent Systems measures 32 inches wide, by 32 inches deep, by 63 inches tall. It’s a nice size to accommodate mature plants without taking up lots of space in your home.
The cover is made from black 600D canvas, with contrasting blue trim around the edges and zipper. A discreet Opulent Systems logo in the same shade of blue is positioned in the top right-hand corner.
All the seams are double stitched to stop light from leaking out.
There’s a useful window at the front, generous enough to give you a good view of your plants. The cover opens by rolling to the left, and is secured with Velcro. Just make sure it’s correctly positioned when you close it to avoid light escaping.
The hanging beam is designed to hold equipment up to a total of weight of 110 pounds. That makes it pretty robust, but make sure you position your accessories evenly along its length. Concentrate the weight in one area, and it may still buckle and collapse on your plants.
The frame is made of metal, with metal corner pieces too. It’s easy to clip together and you won’t need tools. And for once, the instructions that are included are very simple to follow.
So far, so good. This is a decent quality tent at a competitive price. There are just a couple of little niggles…
There are a few pin pricks of light around some of the seams. If you want something that’s 100% lightproof, you may need to spend a bit more. Covering them with duct tape is an option, but it’s a bit of a pain.
And, as with the CoolGrows tent, the zippers can be rather stubborn. Take care when opening, or you may find they get stuck. If that happens, you’ll find it hard to get them moving again.
- Robust hanging beam will hold up to 110 pounds of equipment
- Simple to assemble, with clear instructions
- Useful viewing window to keep an eye on your plants without opening the tent
- Not 100% light-proof
- Those pesky zippers aren’t as smooth as they could be.
6. CoolGrows Mylar Hydroponic Grow Tent
If you’ve got an ambitious planting program and room to spare, this enormous tent from CoolGrows could be for you. It measures a huge 6 feet 8 inches high, giving the tallest plants plenty of space. It’s four feet deep and no less than 7 feet 6 inches wide.
There are two vents on the roof, and one on the top and bottom of each side. There are four rectangular mesh covered panels too, two at the back and one each on either side. All that will help keep the air circulating through the enormous growing chamber.
Such a wide tent needs two separate doors, each of which are fasted with a heavy-duty zipper. Each door has its own generously sized viewing window, allowing you to see into all parts of the tent. The window covers roll upwards, and are secured with Velcro.
The shell of the tent is made from thick canvas, double stitched along the seams to keep in the light. And the interior is lined with Mylar, which will reflect 95% of the light back into the growing chamber.
The all-metal frame clicks into place without the need for tools. The poles are bright green too, giving them a fresh, clean look. The frame is sturdy enough to be moved after assembly – but its size means this is a two-person job.
The package includes a removable floor tray, two carbon filter belts, and instructions to put the whole thing together.
We’ve heard one or two complaints about light leakage, with pinprick holes being to blame. This seems to be a quality assurance issue, as it’s not the case with all units. If you get one with tiny holes, they’re easy to cover with duct tape.
- Large enough to house your biggest plants with ease
- Twin doors allow easy access to the spacious interior
- The metal frame is sturdy, and we love the funky green tubes
- Some issues with pinprick holes letting in light
- You’ll need plenty of space to accommodate this one.
7. MELONFARM Mylar Waterproof Hydroponic Grow Tent
If you’re looking for a more compact option, this tent from Melonform could be a good choice. It’s 6 feet 3 inches tall, three feet wide and 1 foot 8 inches deep.
There’s a single D-shaped door with a double zipper for easy access. We like the smart green trim around the zipper and along the edges of the tent too. Even the sock vents are edged in green.
The support beam from which you can hang your kit is particularly robust here. It will hold up to an impressive 220 pounds of gear. That’s more than enough for all the reflectors, fans, lights and ballasts you’ll need for a tent of this size.
The frame is metal, with metal connectors. In addition to the sock vents (closed with a cord and toggle) there’s a mesh-covered rectangular panel. And there’s a window in the door, positioned at a comfortable height for viewing.
Other nice touches are the removable floor tray and handy bag to keep your tools and accessories organized. And there’s a 30-day money-back guarantee and 20-month warranty too.
The shell is made of canvas, and the interior is lined with highly reflective Mylar. The fabric isn’t as thick as some, though, so be careful when you assemble it. Tug it over the frame a bit too vigorously, and it can tear.
As with other tents, we’ve heard complaints of pinprick holes letting the light escape. Test it in a dark room when you set it up and patch up any small holes with duct tape.
- D-shaped door with double zipper gives easy access
- Plenty of sock vents and a rectangular mesh-covered vent too
- Comes with 30-day money-back guarantee and 20-month warranty
- The canvas is fairly thin – be careful not to rip it during assembly
- You may need to patch up tiny holes with duct tape if you want it completely light-proof.
Still confused about which is the right grow tent for you? Here’s our handy guide to making that all-important selection.
Two things will determine the right size grow tent for your needs. The first is the size of your plants. The second is the amount of space you have in your home to accommodate it.
If you want to house mature plants, check their dimensions – spread as well as height. You don’t want to damage them by crowding them too closely together. And remember – you’re expecting them to grow bigger over time!
A large grow tent will give your plants plenty of space – but it will take up a lot of room. Make sure it will fit into whatever space you’re able to set aside for it.
Remember too that some tents will have viewing windows. Most of these are on the front, but some are located on the sides. Wherever you position your tent, you’ll need room to stand in front of the windows to see inside.
How much equipment?
You’re almost certainly going to be using grow lights in your tent. What about a fan? Ballast? Reflectors?
Make sure that the overhead beam in your tent is strong enough to hold the kit you’re using. Add up the weights and check the specifications. The last thing you need is for the whole thing to collapse and squash your precious plants!
One chamber or two?
Do you need a large space to let your plants grow tall and wide? Or do you also want to use your tent to germinate tender seedlings?
A two-chamber tent can offer more versatility than single chamber versions. They’ll include a smaller nursery chamber, often further subdivided with a shelf.
Seed cones and young plants do best sitting on the shelf. You can then transfer them to the floor of the nursery, and finally to the other side, as they grow.
Look for options where the central divider and shelf can be removed. That way you’ll have the flexibility to accommodate larger plants if you need to.
If, however, you’re not going to be growing plants from seed, consider a single chamber tent. There are fewer components so it will be quicker and easier to assemble.
Ready to choose?
We hope you’ve enjoyed our run-through of some of the best indoor grow tents available today. While their fundamental design is very similar, there’s plenty of variation too.
Consider what size will suit both your plants and your home. And check the specifications and warranty before making your final choice.
Our favorite is Vivosun’s two-in-one grow tent. We love the versatility of the dual chambers, and the added extras of the floor trays and tool bag.
Whichever grow tent you choose, use it carefully and you’ll be rewarded with strong, vigorous plants. Happy harvesting!
