Ok here goes, my first grow. I am running in my flower room which is 9'x11'x7' 4x 600w hps lights all with vented reflectors. They are connected with flexible aluminum ducting. I was looking at the sticky where it shows the calculations for configuring your cfm and I'm not sure my 746, i think, Can Fan 8" HO fan is doing the trick. I have a couple of 90 degree angles and with that formula it says i need 1320 or so cfm to maintain appropriate venting. I am having a little heat trouble, staying around the 94 degree mark. I was thinking about adding an intake to my sealed room however the air from my basement is pretty warm itself. That or maybe adding another fan directly to the end of my can fan filter to up my exhaust power a little bit. should i try one of these before the other? also i am running co2 via propane burner. <- not causing the heat problem though because I have just switched to flower and have not used it yet and i am aware that this will also increase the team and that i need to run around 85 or so for the co2. I am using an environmental controller as well. Any help would be great, Thanks!
