if ive got a box and at the top ive got my exhaust sucking air, is it possible to just have a set of large holes at the bottom for bringing new air in. surely it will naturally pull air through (obviously not as much as the fan would). any help appreciated.......... peace
It will work fine, but just remember that once the flowering starts those holes must not leak in light during the "dark phase", you could always make holes and fix some type of tubing, pvc rigid, ducting or even the cardboard inners of foils and food wraps are ideal. good luck.
