These tents usually consist of heavy-duty fabric boxes, on a metal frame. They keep water, light and airflow contained, allowing you to regulate the internal conditions, and create the ideal environment for your plants to grow.
You can do this by adding LED lights, heaters, fans or dehumidifiers inside the grow tent, or in the room around it, to create the optimum growing conditions for your particular variety of plant.
If you want to grow plants indoors, even in winter, you should definitely consider investing in a grow tent. To help you choose one, we’ve selected 5 of the best grow tents on the market, based on their size, quality and affordability.

Our best grow tent is large, high-quality, and packed with helpful features
This Mars Hydro Grow Tent is our favourite grow tent on the market. The relatively large size of 120 x 60 x 180 cm makes it perfect for growing multiple plants and vegetables inside your home.
The metal frame feels sturdy, whilst the tent is made from a particularly heavy-duty 1680D canvas, which is tear-proof and waterproof. It has double-taped seams, and a highly reflective, diamond Mylar lining that helps to keep 100% of internal light inside.
It’s not just the materials that are high-quality – the design is also impressive. A well-placed viewing window allows you to observe your plants’ growth, without disrupting their environment, and the ventilation holes encourage circulation, whilst offering a convenient escape for a fan exhaust.
The waterproof, removable tray at the bottom effectively catches any fallen leaves and debris, making the tent easy to clean. There are straps to keep everything in place, and pockets for tools, which further enhance the tent’s usability.
Overall, this is a well-designed grow tent that’s difficult to beat on quality for the price – and if you do encounter any issues, the manufacturer offers a no-quibble 30-day money-back guarantee. With that in mind, how can you go wrong?
- Made from high-quality 1680D canvas, with double stitching.
- The reflective lining keeps 100% of internal light inside.
- Sturdy frame with metal corner adapters.
- Viewing window allows you to observe your plants’ growth.
- Removable floor tray makes it easy to clean.
- Easy to assemble.
- Pricier than some similar products.
Our best value grow tent is a great introduction for first-time growers
If you’re seeking a more affordable option, check out this Saving Plus Indoor Grow Box. It’s certainly great value, and it could be the perfect choice for anyone looking to try out a grow tent and see if it’s for them, before investing too heavily.
This one features a 600D polyester cover, which is a lot thinner than the Mars Hydro, but pretty average for a grow tent of this price range. The cover has an aluminium lining, to reflect internal light and heat.
At 60 x 60 x 140 cm, this tent is also significantly smaller than the Mars Hydro, so there isn’t as much room for plants or growing equipment – you can expect to fit around 4 potted plants in here.
However, there are hanging poles for lights and filters, and adjustable exhaust vents (although you’ll struggle to fit an extractor fan in this one).
It also has a removable floor tray, held in place with Velcro, to help with cleaning the tent.
Ultimately, if you’re looking for an affordable, functional grow tent to test the waters of growing indoors, this grow box should meet your needs – and may even exceed your expectations.
- Made from water, light and air-tight 600D Oxford polyester.
- Light and durable steel-coated frame.
- Hanging poles for filters and grow lights.
- Removable Velcro floor tray for easy cleaning.
- Easy and quick to assemble.
- Our most affordable grow tent and excellent value.
- No viewing window.
- Comparatively small and low height – not much room for plants or growing equipment.
- Difficult to source replacement parts in the event of damages.
This sturdy grow tent is well-made, user-friendly and affordable
Our third grow tent is this Hydro Box from Rimarup. This one measures 80 x 80 x 160cm, so it’s in-between the previous two options. It features a similar design to the Mars Hydro, but it’s made of 600D Oxford polyester cloth, the same as the Saving Plus.
This material feels thick and good quality though, and it does have a reflective lining made of the same Mylar material as the Mars Hydro, which is waterproof, and highly effective at blocking out light. There’s also a removable floor tray made of the same material, which catches debris and allows for easy cleaning.
If you want to check in on your plants without disturbing them, you can do so with the built-in, eye-level viewing window. There are also the usual ventilation holes and storage pouches, which make it easier to set up and use.
Speaking of which, assembly of this tent is quick and easy and doesn’t require any tools. There are bars running across the top that you can use to hang lights or filters – although at 160cm, it’s not the tallest option, and you might struggle to fit everything you want inside.
Other than the height issue though, this is another high-quality, feature-packed option that feels much more expensive than it actually is – we’re sure you won’t be disappointed.
- Sturdy metal frame.
- Heavy-duty 600D Oxford polyester cloth with double-stitching.
- Highly reflective diamond Mylar lining.
- Viewing window to allow you to easily observe your plants.
- Removable Mylar floor tray for easy cleaning.
- Easy, tool-free assembly.
- Comparatively low 160cm height might not be enough for hanging lights and filters.
This tall grow tent has more room for lights and growing equipment
If you’d rather your grow tent have a bit more height (and you’ve got the ceiling for it), this Foxhunter Portable Grow Tent is 200cm tall, and 120 x 120 cm square, so there’s plenty of room to hang all your LED lights and filters.
Included with this one is a handy carry bag, to make it easier to transport and store. The tent has a Mylar reflective lining, plenty of vents, and a removable waterproof floor, to allow for easy cleaning of any spillages.
The main body material is a heavy-duty 600D polyester, which is waterproof, light-proof and air-tight. However, the high-quality tent is let down by the somewhat flimsy poles, and low-quality plastic corner fittings, which make the whole tent feel a bit less stable than others.
This may not be the best quality grow tent on the market, but it’s still fully functional and is ideal for those who want a taller indoor growing area – for a reasonable price.
- 600D polyester material – waterproof and light-tight.
- Silver Mylar-lined reflective interior.
- Tall height offers more space to hang lights and filters.
- Lots of vents for exhausts, cables and air-cooled lights.
- Removable waterproof floor to handle spillages.
- Includes free carry bag for easy storage.
- Poles are a little flimsy.
- Pole connectors are made from plastic and are not the best quality.
A compact and sturdy grow tent, with lots of vents
On the other hand, if you don’t need the extra height, our final grow tent might be for you. This Finether Hydroponic Grow Tent is made from polyester cloth and is again lined with the popular Mylar reflective material. It features a sturdy frame, and a removable floor tray, for easy cleaning.
The tent has 5 vents for electrical outlets and cables, and 3 Velcro-sealed, mesh-covered filters to provide airflow, whilst keeping bugs out. Inside, there are 2 removable support bars on which to hang lights, fans and growing equipment.
This one is relatively easy to assemble and doesn’t require any tools to do so. At 60 x 60 x 140cm, it’s one of the two smallest grow tents on our list, along with the Saving Plus.
If you want a larger grow tent, we’d recommend you go for the Mars Hydro – but if you only want to grow a couple of plants, this compact grow tent will do the job, and it is excellent value.
- Rigid and sturdy frame.
- Removable flood-proof tray for easy cleaning.
- Thick polyester cover with reflective Mylar lining to keep light in.
- 5 vents for electrical access, and 3 mesh-covered filters for airflow.
- Easy, tool-free assembly.
- Comparatively small – won’t fit as many plants.
How To Set Up A Grow Tent
To set up your grow tent, you should follow the assembly instructions provided by the manufacturer. Here’s an idea of the process you can expect to follow:
1. Lay out your components
The first thing to do upon receipt of your grow tent is to check the contents and make sure nothing’s missing. Lay out all the parts ready to assemble, and gather any tools that you may need, such as a screwdriver.
2. Build the frame
Once you’re ready to assemble your grow tent, start by constructing the frame, according to the instructions. Once built, place the frame in the location where you want your grow tent – a wooden or tiled floor is ideal, in case of water spillages.
3. Add the covering
With the frame in position, you’re now ready to add the covering. This is usually made of canvas or nylon, with a reflective lining. Make sure it fits snugly over the frame.
4. Set up your grow lights
The next step is to add the equipment that will allow you to control the environment inside your grow tent. One of the most important of these is usually lighting. Mount your grow lights securely to the frame of the tent and feed the cables through the cord holes. If you want your lights to run on timers, you’ll need to set these up too.
5. Hang a thermometer
Position a thermometer inside the grow tent to enable you to monitor the internal temperature. This is important to make sure your lights are not generating too much heat for your plants to grow.
6. Address air circulation and humidity
Another important factor in making your grow tent successful is good ventilation. Ideally, hang a carbon filter from the frame inside the tent, and angle an extractor fan towards it, with the exhaust running to one of the tent’s ventilation holes. If you’re using a dehumidifier, install that now as well (see more below).
7. Turn it on
Once you have everything in place, turn your equipment on and make sure it’s all working correctly. Check for safety hazards, such as power cords which could cause you to trip.
8. Moving day
If everything is working as it should, congratulations! You’re now ready to move your plants into their new home. Make sure to monitor your grow tent closely and adjust the conditions if necessary.
Do I Need A Dehumidifier For My Grow Tent?
A dehumidifier can play an important part in making a grow tent successful. Using a dehumidifier will remove moisture from the air in your grow tent, helping to prevent mould, powdery mildew, and other problems caused by too much humidity. Research suggests that plants prefer a relative humidity level of around 60%.
You can place a dehumidifier inside or outside your grow tent, depending on the size of the tent. If there’s no space for a dehumidifier inside your grow tent, simply place it outside, in the same room. If your room is large, you may need multiple dehumidifiers – in this case, make sure they are well spaced out within the room.
The airflow inside your tent is also important; if the extractors in your grow tent remove more air per hour than the maximum capacity of the dehumidifier, you will need to place it outside the tent. You can reuse the water extracted from the air by your dehumidifier to water your plants.
