Hello all, my temp in grow room is 78-80 however at the top of plants it is high 80s. I have two fans blowing 186 cfm 4 inch fan and phresh filter. I have one 8×8 intake air opening covered with carbon filter. Any advice would help. Can I cut a 4 inch hole and add four inch blackout duck to create more air flow? And if so how do I filter the inflow air.
