Hello,
ive recently seen reply of yours about CFM and passive intake. I will be building a grow room 6'x4'x5' total of 120 cubic feet. It will have 4 400watt led (200w draw each). room will be in a basement, cold in the winter and hot in the summer (little cooler in the basement). I read the LED grow rooms needs to be 80-85 degree. Im in the process of a 4" inline or 6" inline with speed controller. The end result will be the fan pushing air threw a DIY 5gal scrubber out side of the room. For the passive intake I will be using a 2 elbows (size is pending) per intake hole and a few feet of duct work to reach a radiant radiator for the winter season (will also have CHE on a thermostat). What size fan should I buy and how many/big holes should I make for passive intake. thank you for your time
