lolz at your statment bro, you want as much air moving as you possibly can.

take my setup for instance

2 600w hps in a 2.8x4x6 ft area

i have both these lights in cool tubes with a 600cfm fan blowing through it. Then i have a seperate 400cfm vortech fan pulling air out of the cab 24/7

so a total of 1000cfm when light on cooling the cab and exchanging air and at light out i still have the carbon scrubber scrubbing. keep that thing on 24/7 dude

Battling temp Well now i have my 7week old seedlings in my grow room,they look really healthy.I have them under a 4oowatt sodium the temp sits at 80.I have my carbon filter fan comming on for 15mins an hour.My problem is i turned my other 400watt on last night but the temp went to 100 so i turned off one of the lights.What i need is any tips to bring the heat down.I get one problem sorted then another pops up lol.Whoever said growing weed was a piece of cake needs a slap.....
