i would like to know what cfm i would need for the intake and exhaust fan for a 2mx2mx2m grow tent. i heard that you need more cfm output for the exhaust than the intake.
Hi Guys,I will be using cfls throughout the vegetative stage and then a 600w hps throughout the flowering stage. Can i use the same cfm fans whith both the cfl and hps lights?
Thankyou.
