To build a grow box, line a cabinet with Mylar, suspend lights from the ceiling, cut two vent holes, and turn on the power. This two-hour project requires a cabinet, Mylar, a stapler, scissors, lights, tape, a saw, a screwdriver, screws, rope ratchets, a filter, a fan and vent ducting.
- Line a cabinet with Mylar
Place the cabinet in a convenient location. Open the doors, and line the interior with Mylar fabric. Staple the Mylar in place.
- Install lights
Screw rope ratchets to the cabinet ceiling, and suspend grow lights from them.
- Create the air intake vent
Use a reciprocating saw to cut a 12-inch hole near the bottom of the back cabinet panel. This is the air-intake vent. Cover the vent with a disposable air-conditioning filter, and attach it with duct tape.
- Cut the exhaust vent
Cut a 4-inch hole in the cabinet ceiling, and attach a 4-inch vent duct. Attach the open end of the duct to a 4-inch exhaust fan. The front of the fan must point away from the grow box.
- Connect the power
Plug in the lights and exhaust fan, and turn on the power. Verify that the fan blows air away from the cabinet.
