i would think it would be good to hook up your system with the strongest fan to your hood. have the fan suck air out of your hood through your fan blowing out to your filter and have a passive intake. if temps are still alittle too high then try and put a fan on the intake(if you dont have a vaccum on your closet then your whole place will smell as its not goin through your filter)
texas grass Reviewed by texas grass 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
