I have a fan (voxtex inline, 400 cfm), a paint can like activated carbon filter, a Hortifarm glass lens'd air cooled reflector (attached to a 400 watt bulb) and I'm growing in a closet (apprx. 2' x 4', off the top of my head). What order should I put them in? I was thinking, (top of grow room to outside) Reflector (one end open and one end attached to ducting)-> ducting -> filter -> fan -> outside. Should I put a passive air intake or use some fans or what? Thanks in advance.
use a passive intake at the bottom.. like 10-12". you want it to run filter----> light hood----> fan --------> outside good luck man
