Description

Commercial floor space without building a room

The Green Box Tent 800 x 400 x 220 covers 32m²: 8m x 4m at 2.2m high, big enough to run a small commercial crop or several separate trials under one cover. Doors on the long sides as well as the ends mean you can get into the middle of the room without walking its full length. Greenbox build it the same way as the rest of the range, with 600D oxford cloth, a 620D diamond mylar lining and a steel push-and-click frame with heavy-duty corners, and it ships crated on a pallet. On a room this size, stale corners and humidity pockets are the usual problem, so every wall carries 12-inch duct sockets high and low plus lightproof mesh vents to spread intake and extraction along the whole length.

Key Benefits

  • 8m x 4m floor, 32m², for commercial-scale or multi-zone growing
  • Side doors along the length as well as the ends
  • 620D diamond mylar lining and 600D oxford outer
  • 12-inch duct sockets spaced along every wall to avoid dead air
  • Steel frame and roof hangers built to carry a room full of lights
  • Removable floor liner and PVC-free, non-toxic materials

How to Use

  • Clear a level floor of at least 8.2m 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.
