You should put your fan on the exhaust hole (near the top of the box), and leave intake as a passive intake (near the bottom).
Duckys Reviewed by Duckys on . Will this box work for a single plant? Please Help! 1) Alright the dimensions are in the pics and i was just wondering wether or not this is big enough for a one plant grow up. Ill be takin the shleves out and putting on a door if so. 2) Is this fan useful, or is it too powerful for such a small area. Could I use it to push the air out somehow? 3) How many CFL lights/watts would I need for Veg/Flowering. Iv been reading all day but havent found any ones grow like mine ANY tips of where i should place lights, vents, pots etc... would Rating: 5
