Im gonna be attempting my first grow with snow white seeds i got from nirvana. Dresser is 3ft x 2ft x 14in deep. I have a 150w hps light with 2 24w cfls. Im only trying to grow two plants. I was wanting some advice on exhaust would i be able to get by on two pc fans? Pic of current setup

I still don't know why this isn't a sticky. I see ventilation questions everyday on here.
