Yup, passive intake is the best way to go, as is filtering the air as it exits. makes no sense pumping it back into the growroom, to be filtered again.
You mentioned cutting a hole...is that hole going to be made in the walls of your appartment? If so, I hope you and the appartment staff are on good terms. A visit from the police responding to a destruction of property call, would likely suck.
Rusty Trichome Reviewed by Rusty Trichome on . Venting issue Alright, I'm currently running a 600 watt HPS light. I am using a Super Sun 2 hood, with the tempered glass, and a Lumatek digital ballast. Heat is a problem, atm my highs are 85 degrees, but this is using a 177 cfm Vortex blower to push air in, with a passive exhaust. Thing is, the vortex is about to be hooked up to a can filter when I start my 12/12 cycle. So I bought a 6 inch Ecoplus, and am planning on hacking a hole (okay, sawing a square in the top right and bottom right corners) in Rating: 5
