hi im presently setting up 3 4x4 tent in a 10x10 space with 600w hps in 2 for flower and 600w mh for veg with 6'' cooling hoods. i was wondering how do i setup venting to use the less fan possible and where should i put carbon filter. i will be using a window mounted a/c to cool the 10x10 an exhaust trough the same window next to the a/c
