Mainely Growing Weed Reviewed by Mainely Growing Weed on . CFL v HID 4x4 setup Hi, my setup for a personal medical setup is a 4x4x7 grow tent in the bedroom. I have a 4x4 flood and drain table, Vortex 440CFM fan sucking through an air cooled hood and scrubber to outside the house. I have 2 6 inch passive vents into the tent from the bedroom. I have left the vents passive to allow the tent to always be in negative pressure, leaks in pressure will therefore always be into the tent mitigating any leaked smells into the room. I have a 1000watt digital ballast switchable Rating: 5
