This gonna work? Its working great right now with negative pressure in my 8'x8'x6'7" tent but there is only 1 light in there right now.

Theoretically it should work fine. As long as the airflow is enough to get through all that ducting to be able to get the heat out faster than it can build up.

Check into one of these.

I have a cheaper version that worked real well for my cooltube for a 1k light. This one is the "industrial" version but they have a 1/2 hp one for like 100 bucks less and I bet you could find them all over ebay or craigslist if you search.

heh. i dunno botu 200 cfm man. i used a 800 cfm fan in a much similar style back a while back and it was cuttin it. id go with a 1200 cfm inline fine if i were you. cuz you said its goin through the lights and a carbon filter. is there any turns in the ducting? cuz that will knock of a significant amount of cfms right there. go with something bigger.

edit. yeah you are gonna have 2 uturns and an elbow in that bitch? deffff go with something bigger. i use a 200 cfm blower for exhaust for my t5s in my clone box...

Can anyone tell me how much louder the stronger blowers are? i feel liek im at my threashold for noise
