The UK's Premier Grow Tent Supplier

If you’re growing indoors, the first thing you need to do is pick a grow room tent. Strictly speaking, you don’t need to grow in a tent. You can grow in a room, a greenhouse, or even convert a cupboard.

However, grow tents are convenient, practical and a great value way to create the ideal growing environment for plants. They’re a cost and time-effective alternative to building an entire grow room. Our range of grow tents give you an enclosed growing space, where you can control every aspect of the environment. 

By reducing the floor space needed to grow plants, and by keeping your setup contained, the range of grow tents here at GroWell offers ultimate convenience and fantastic value. BAY6 growing tents are our budget grow tents. Whereas the grow tents in the Budbox range offer quality features that can hugely improve your growing environment, such as:

  • Highly reflective sheeting
  • Sturdy metal frames
  • Robust plastic corners 
  • High quality zips that prevent light leaking
  • Vents and access holes 

Grow tents are available in a wide range of sizes to suit all requirements and prove to be quick and easy to assemble, so why not check them out and take your growing to the next level?

Grow Tent FAQs

Here are some common questions we get asked about grow tents.

What should I look for in a good indoor grow tent?

Poles: Look out for strong metal poles that won’t buckle under the weight of your lights and fan.

Canvas: You’ll also need a strong, thick, canvas with a tight weave. One that won’t tear and will reduce the amount of noise that escapes.

Stitching: Decent growing tents have tight stitching that holds the canvas together, adding strength in the tent corners and around the tent zips.

Corners: Pay special attention to the corner pieces. Remember, corners hold the frame together… when you hang your equipment the corners need to be strong enough to take the weight of your grow tent accessories.

Zips: To keep the canvas tight, and to stop light seeping out, choose a hydroponic grow tent with a good zip that won’t burst. The best tents have light baffles behind zips

Interior: Pick a grow tent with a reflective interior - the more reflective it is, the less light is lost to walls, and the more light will reach plant.

Access: Finally, you need to make sure there are enough access ports, and that they’re in the right places.

Do I need a Grow Tent?

There are lots of reasons to choose a grow tent.

Firstly, it’s cheaper. You don’t have to light, heat, cool & humidify a whole room - just the space inside your tent.

This means you don’t spend as much on your equipment – fans don’t need to be as powerful and you don’t need as many lights.

Over time, running costs are also lower.

Is a silver mylar tent or white grow room tent better?

Ultimately, you’ll get excellent results in either tent. But white tents have the edge.

They reflect light more evenly. As a result, you get fewer hot spots, and plant growth will be more uniform. Overall, white interior tents have been shown to be 1 – 2oC cooler than silver ones, too.

This doesn’t mean that silver grow room tents are bad. They’re just not quite as good as white interior tents.

What are the standard grow tent sizes?

We find, most people buy the following larger sizes of grow tent:

  • Large Grow Tent (1m x 1m)
  • XL Grow Tent (1.2 x 1.2m)
  • XXL Grow Tent (1.2m x 2.4m) tent.

All of these grow tents are 2m high.

These are the standard grow tent sizes, but you can get bigger, smaller, shorter and taller tents too.

How do I know what size grow tent to buy?

You’ll need one that has enough space for your growing equipment and growing system without cramping plants.

You also need to take your grow lights into account because you want to make sure the light intensity in your tent is right.

Generally speaking, this is how much space you need for each HPS light:

  • 250W light: 0.75m x 0.75m area
  • 400W light: 1m x 1m area
  • 600W light:1.2m x 1.2m area
  • 750W light: 1.3m x 1.3m area
  • 1000W light:1.5m x 1.5m area

Which is the best brand grow tents to buy?

We mostly sell BAY6 and BudBox grow tents. The best one depends on what you’re looking for in a tent. Let’s just say there’s a reason why some tents cost more than others.

BAY6 grow tents are entry level tents. They do the job and don’t cost much to buy.

BudBox grow tents are known for their quality build. They have a thick canvas, durable zips and tight stitching.  To keep light out, their canvas has a dense weave and their reflective coating is thicker than that of most tents. There are light baffles for anything that’s been sewn, too. To strengthen the frame, BudBox tents have steel corners. You have more layout options with a BudBox tent, too – they have more ports than most other tents and there are no central bars running across your floor. They also have a white interior, which is known to prevent hot spots.

Which is the cheapest growing tent to buy?

BAY6 grow tents cost less, but a BudBox grow tent will last a lot longer which could mean you spend less overall.

How many growing tents do I need?

Strictly, you only need 1 hydroponic tent.

However, if you want to get more cycles out of your year, you need at least 2 tents – one for propagating and vegging, another for flowering plants. With two grow tents you can start propagating a new crop while your previous one is still flowering. 

For best results, you’ll want three tents - one for each stage of growth. If you keep a mother plant, you’re best off keeping her in a tent of her own.

Do you sell propagation tents?

We sell BAY6 propagation tents and kits. They’re compact and fit into small spaces easily. You can stand them up or lie them flat – whichever you choose.

Do I need a mother plant tent?

Ideally, yes. Some growers keep their mother plant in their veg tent, but, she has different environmental needs. Kept in a vegging tent, she’ll be taller than the other plants in your grow tent, so your light height won’t be right for her. She can also end up casting a shadow over nearby vegging plants so that they don’t get enough light.  For best results, the mother plant really does need a tent of her own, or at least her own compartment in a multi-chamber grow tent.

How to set up a grow tent?

It depends on the brand, but normally you lay the canvas out then start constructing the frame inside the base of the canvas. Once the frame is done, you can simply pull the canvas over the frame and zip it up.

Can I use a grow tent for a closed loop room?

You can, but it’s not recommended. Closed-loop rooms need to be completely sealed off – grow tents are built for air exchange. There are entry ports, zips and intake flaps that air can enter through. You’ll also be hanging heavy climate control systems in a closed loop room and some tents will be unable to withstand the weight.

Ideally, for a closed-loop room you need an insulated room with solid walls.

Do you sell loft grow tents?

Yes, we do. Loft grow tents have a tapered design so they can fit in the eaves of a loft or attic. We stock a range of BudBox and BAY6 loft grow tents in various sizes.

Do I need to use a filter with a grow tent?

Yes, we would suggest you use a carbon filter. It’s vital for odour control. We stock a wide variety of carbon filters for grow tents. If you opt for a grow tent kit, a carbon filter is included (as part of your extraction system).

How to adjust the humidity in a grow tent?

Read our blogs -  'VPD in a Nutshell', 'Humidity Rising? How to Dry Up' and 'Harnessing the Power of Humidity'. They have some great tips for controlling the humidity in your grow tent. Whether you want to increase the humidity or lower the humidity our blog posts will walk you through the process and considerations.
