hi all
i have a question on how many fans you should need ,i have a 4inch carbon filter connected to ruck 4inch fan thats sucking out nasty smells but i only put this on late on when the grow is nearly ready .i have a tall stand up fan in the room but its a bit bulky & in the way its just really pushing air about ,
do i really need a another fan sucking fresh clean air from out side the room ,where should it be fitted if i do .? high up like the extractor or does it not matter ,
as anyone any pics to give me an idea what to do ,
thanks
jay
