All of the fans the size you will need are at least 6". You need at least a 400 CFM fan for 2-1000W lights.just picked up a big light hood and with the german reflective inside. anyway it has 2 vents on it. one at each end. they are 6" . is it crutial to use a 6" fan and ducting or can I reduce that to a 4" fan and ducting? Im going to be using (2) 1000hps and a crap load of cfl, t8 , t5 and red/blue high power led. So the only real heat producers will be the 2 vented 1000hps. I only have 1 rt now but will be adding a 2nd and the same vented light hood. any sugestions
Stay with 6". You will be glad you did in the long run.
