grow box

im making a pc towwer grow box. i wanna know whats the best fan orentation. 2 fans? 1 fan? directions of fans? locations of fans? also i have 2 fans at my disposal, but ones weakerr than the other, what should the weaker one be?

welp...with a PC case it depends on the amount of CFL's yer working with and how large the case is...you want an exhaust fan basically up top where the power supply usually sits, pushing air out the back(you would want this to be your stronger fan)...and an intake fan down on the bottom on the opposite side of the case(so probably the bottom front)...that will give you nice airflow straight up through it pulling the hot air out the top. That's probably the best orientation for a regular tower case
