Do i need to run supply fan pulling outside air constantly along with return fan ? Or only when lights are on ?
Best to have it run when lights on and off. If u have a fan pulling out of the tent there is no need for fan to push air into tent. The exhaust fan will pull the fresh air in on its own
Thanks Liljoe, my room is air tight and to hot to run supply fan during daylight hours !! Would running exhaust fan help this room when supply fan isn’t running ?
I run my fans 24/7 when I have bigger plants. When seedlings I don’t use them all at the same time.
Yes, exhaust fan will pull as much air into tent as u r pullin out. My opinion is intake fan a waste if running exhaust fan
@big55 Is your grow room still running hot?
No, it’s doing great !! Thanks
