Dark Room model DR100 measures 39.6" square and is a good choice for growing flowers or small vegetables to maturity. A 3 x 3' plant tray fits nicely. You could use either a 2-foot HO T-5 Fluorescent or a 250W to 400W HID light system. 

As with all Dark Rooms, the Dark Room DR100 is lined with highly reflective thermal film in the interior. This film is 95% reflective, waterproof, and provides 97% insulating protection. The innovative, adjustable Dual-Sock Ports allow you to attach fans, filters or ducting to both sides of the tent wall without clamps or reducers. Mini Dual-Sock Ports are built in for your power cords and hydro tubing too!

Keeps your growroom light-tight. Dual-Sock Port locations:

2 (6.7") opposing ports at reflector level for air-cooling
1 (6.7") port in back corner of roof for exhaust fan
2 (6.7") opposing ports near floor level for intake
2 (2.75") cord / tubing ports

DarkRoom materials are non-toxic so there are no harmful gasses to damage sensitive plants!
