Green Box Tent 400 x 400 x 220 – 4m x 4m Grow Tent

A 4m square grow room you can walk round on every side

The Green Box Tent 400 x 400 x 220 gives you 16m² of square floor under a 2.2m roof, enough to run a grid of lights over one large canopy or split the space into zones with walkways between them. A square footprint keeps every plant within reach from one side or the other, so you can tend the middle of the room without climbing over pots. Greenbox build it from 600D oxford cloth lined with 620D diamond mylar on a steel push-and-click frame with heavy-duty steel corners, and it arrives crated on a pallet. Upper and lower 12-inch duct sockets and lightproof mesh vents on every wall let you move enough air through a room this size to keep heat and humidity under control.

Key Benefits

• 4m x 4m floor, 16m², square so every plant is reachable
• 2.2m height for hanging lights, filters and fans with room to work beneath
• 620D diamond mylar lining to bounce light back onto the canopy
• Steel frame and roof hangers with silicone pads to carry heavy equipment
• 12-inch duct sockets top and bottom plus 3-inch cable ports and lightproof vents
• Uplift irrigation bar and hanging straps for tidy pipe and cable runs

How to Use

• Clear a level floor of at least 4.2m x 4.2m and unpack the crate beside it; the steel tubes are numbered, so lay them out against Greenbox's frame drawing before you start.
• Build the frame with two people, clicking every joint fully home, then draw the cover over from one end and close the zips.
• Hang lights, carbon filters and fans from the steel roof hangers and straps, never from the fabric.
• Run extraction from the upper 12-inch sockets and intake from the lower ones, and cinch the double cuffs tight round the ducting.
• Fit the floor liner before the pots go in, then check for light leaks with the lights on inside and the room dark.
