Which Indoor Grow Tent Do You Need?
Choosing an indoor grow tent isn't easy.
Read our handy buying guide to work out which tent you need.
Before buying any indoor grow tents, there are 8 questions you need to answer.
1. How much space do you have?
Before you buy anything, you need to know how many grow tents, and what size tents, will physically fit into your growing area.
Don't forget to leave enough space for ducting. You may need an extra 250mm of space for ducting to come out of the top, back or side of your tent, depending on the model you choose.
2. How many grow tents do you need?
For most people, the answer is at least 1, probably 2 and if you’re really going for it, 3.
Most people use 1 tent for propagation and another for vegetative growth and flowering. For the best results, you’ll use a separate tent for each stage of growth.
You don’t need much space...
...since cuttings & seedlings need a low light intensity. Use a small propagation tent - they aren't very high.
For vegetative growth
Your plants are still quite small
A lot of growers opt for smaller tents as it makes maximising your light and managing your environment much easier.
If you want to keep propagating and vegging plants in a single tent, use a Secret Jardin Lodge tent.
Most growers will be using 600W lights (and larger)
You need a tent that’s high enough for plants to grow to their full size. Most main grow tents are at least 2m high for this reason.
Entire cycle in one tent
Though we don’t recommend it, you can grow right from cutting to harvest in one tent.
However, this does mean you’ll end up growing fewer plants.
Most growers propagate and veg their next batch of plants in specific, smaller tents while their first batch is flowering in their main tent. Doing this means that you grow more plants overall.
3. What’s your budget?
Once you know the size and number of tents you need, it comes down to costs.
Don't be fooled into thinking a cheaper tent costs less overall.
Better made tents may cost more, but they also last longer and help boost yields. Invest in a better tent from day dot and you'll save money in the long run.
Here are the best indoor growing tents you can buy for each budget:
BAY6 Grow Tents, from £39.95
If you’re a beginner or bargain hunter, BAY6 Grow Tents are a good bet.
They’ll survive for at least 1 – 2 crops (even more when well maintained).
For such a low cost, you won’t get a better build than this. If you’re just finding your feet, it’s a no brainer.
Mammoth Elite Tents, from £444.95
Meet the daddy of all indoor grow tents - Mammoth tents! If you’re pushing for bigger yields, these are by far the best to buy.
Each one's armed with steel frames, a durable cover and jamproof zips. They’re completely watertight too. You could fill yours with water and it WILL NOT LEAK.
Treat yours well and it’ll last a lifetime!
4. What grow lights are you looking to use?
Your choice of light and choice of tent should go hand in hand.
The more intense your grow lights, the bigger and taller your indoor grow tent needs to be.
As A Rule...
Aim for a height of:
- 200cm – 250W/400W/600W high intensity discharge lights
- 240cm - 750W /1000W lights
Go no lower than:
- 180cm - 250W /400 W /600 W high intensity discharge (HID) lights
- 200cm - 1000W lights
They’re very low intensity and produce hardly any heat. A small propagation growing tent will do the trick.
250W & 400W lights
Go for a 2m high tent if you’ve got room for it.
You can get away with a tent as small as 160cm in height. But don’t be surprised if you run out of headroom as your plants reach maturity.
You’ll need a tent that’s at least 2m high (preferably with a 1.2m x 1.2m floor area per light).
You can get away with a 1m x 1m tent, but you’ll be creating quite an intense growing environment. Managing temperatures might become tricky.
1000W lights and Advanced lighting solutions
Now we’re talking. You’re looking at a 2.4m high ceiling Mammoth grow tent. All that headroom allows the heat from these high intensity lights to dissipate.

5. Which reflectors are you going to use?
When using one grow light
The shape of your indoor growing tent needs to match the shape of light (footprint) created by your reflector.
The Northstar reflector has a uniform, square footprint. It’s perfect for a square 1.2m x 1.2m tent.
Multiple light set ups
Choose reflectors that’ll give you a lot of light crossover (or overlapping light) in a tent with multiple lights.
Light crossover has several benefits:
- Plants get a more intense light
- Growth is more uniform – you get an even light intensity across a larger area
Reflectors like the Adjust-a-Wing are great for this.
Use two of them together in a 1.2m x 2.4m tent and you’ll get great results.
Air cooled reflectors
6. What growing system and equipment are you using?
As a bare minimum you'll need space for your growing system, extraction system and lights. You might also need space for heaters, humidifiers, fans, dehumidifiers and other bits of kit.
Most of our growing systems have a flexible size and shape to fit in most set ups.
If in doubt, call us, start a live chat or visit your local store.
7. Do you want a white or silver interior?
White lined tents (like our BudBox range) are incredibly reflective and retain a lot less heat than silver lined tents. Peak temperatures in silver tents can be 1-2oC warmer than those in a white tent of the same size. This means you can sometimes experience heat problems in silver tents.
There are exceptions – you won’t have heat problems in a small propagation tent, so silver is perfectly fine.
Silver also suits the 2.4m High Ceiling Mammoth Tents, since the extra headroom prevents temperature issues.
8. What sort of features do you need?
Here are some core features to look out for:
Accidents happen, a waterproof tent is great for damage control.
Every 1% of light lost results in a 1% loss in yield. A reflective interior will help minimise light lost to your walls.
Burst your zip and your grow tent won’t be light-tight. The canvas on your tent will become loose, too.
The corners of your indoor grow tent hold the frame in place and take a lot of weight. They need to be well made.
Strong, metal poles:
Weak poles will buckle under the weight of lights and fans.
The more ports you have, the more options you have when it comes to positioning your equipment.
Strong fabric will be less likely to tear, help keep pests out, stop odours escaping & reduce noise.
