A grow tent gives you a clean, lightproof, fully controllable growing environment anywhere in your home – and setting one up takes a single afternoon. Here is the complete step-by-step process we recommend to South African growers, from choosing a spot to dialling in your climate.
Step 1: Choose the right location
Pick a room with access to power, a temperature that stays between 18-30°C, and somewhere you can duct exhaust air (a window, roof space or vent). Garages work well in summer but insulate poorly in Highveld winters – a spare room or large closet is usually more stable.
Step 2: Size your tent
- 60x60x140cm: 1-2 small plants, herbs, or seedlings.
- 90x90x180cm: the most popular starter size – 2-4 plants.
- 120x120x200cm: 4-6 plants or higher-yield setups.

Step 3: Assemble the tent and install your light
Assemble the frame, pull the canvas over, and hang your LED using the supplied rope ratchets. Start with the light at maximum height – you will lower it as plants establish. A quantum board suits 60-90cm tents; larger tents benefit from bar-style fixtures for even coverage.
Step 4: Set up ventilation
Mount your inline fan and carbon filter inside the roof of the tent: air flows through the filter, through the fan, and out the ducting. A 4-inch system suits tents up to 90x90cm; go 6-inch for 120cm tents. This removes heat and odour and gives plants fresh CO2. Add a small clip fan for gentle air movement across the canopy.
Step 5: Dial in your environment
Place a thermo-hygrometer at canopy height. Target 22-28°C and 60-70% humidity for young plants, dropping to 40-50% in flower. During hot summers run lights at night to keep temperatures down; in winter, the light’s own warmth usually keeps a tent comfortable.
Quick checklist
- Tent assembled, zips light-tight
- Light hung with adjustable ratchets, timer set (18/6 veg or 12/12 flower)
- Fan + carbon filter exhausting out, intake vents open
- Thermo-hygrometer at canopy height
- Trellis net and plant supports ready as plants grow
Frequently asked questions
Do I really need a carbon filter?
If odour is any concern, yes – a properly sized carbon filter removes virtually all smell from exhaust air.
How much noise does a grow tent make?
A quality inline fan on a speed controller runs at a quiet hum – most growers find it quieter than a fridge.
What does a complete setup cost in South Africa?
A 90x90cm tent, 200W LED and 4-inch ventilation kit starts around R8,500-R10,000 as a bundle – see our current kit pricing.
