Ok I'll make this quick. 4'x4'x6'6" flowering tent with 600w air cooled hood and a huge carbon filter. My question is in regard to my 400cfm inline fan. Ive decided to have my ventilation run from carbon filter - ducting - hood - ducting - fan. However, I can't decide whether to have the fan inside or out of the tent. This tent is in a 4'6"x8'6"x7' foot storage room in my basement with a 4'x2'x5' tent for veg. ANY ventilation advice would be helpful.
