Hi guys I have a 3 by 3 by 6 grow closet with a 168 cfm inline fan connected to a carbon filter rated for 200 cfms with a 4 inch hole cut for intake. I am running a viparspectra 600 led and this set up is working great for now. But for the winter instead of heating my grow closet (since the intake is coming from outside), I was thinking of buying a 400 w HPS/MH light, would this be adequate to heat my grow room from temps around 40 degrees? Plus should I get a wing hood or air cooled in my situation? Thanks!
