Description
The largest room in the Green Box range, at 2.4m high
The Green Box Tent 900 x 450 x 240 is the biggest tent Greenbox make: 9m x 4.5m, 40.5m² of floor, and a taller 2.4m roof that leaves extra headroom for lights, filters and ducting over a full-size canopy. It is built for commercial growers and serious hobby rooms that would otherwise need a purpose-built space lined and sealed. The cover is 600D oxford cloth with a 620D diamond mylar lining over a steel push-and-click frame with heavy-duty corners, and it ships crated on a pallet. Side doors along the length, 12-inch duct sockets high and low on every wall and lightproof mesh vents give you the access and airflow a room this size needs to keep temperature and humidity even from one end to the other.
Key Benefits
- 9m x 4.5m floor, 40.5m², the largest Green Box tent
- 2.4m height for more room above the canopy
- Side doors along the length so the centre is easy to reach
- 12-inch duct sockets spaced along every wall, with 3-inch cable ports
- 620D diamond mylar lining and 600D oxford outer
- Steel roof hangers with silicone pads and hanging straps
How to Use
- Clear a level floor of at least 9.2m x 4.7m 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.
