Order of Vent System and Passive?

Discussion in 'Grow Room Design/Setup' started by PurpleZebra, Aug 11, 2008.

  1. 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.
  2. any advice?
  3. use a passive intake at the bottom.. like 10-12".

    you want it to run filter----> light hood----> fan --------> outside

    good luck man
