So I'll post some pics of my new grow room but I was wondering if I could get some help, mainly for safety. I have currently 1 20" box fan blowing downward past the light (to cool it as well) and onto my plants. The room is about (closet) 2' X 4' and I'm using a 600 watt HPS and MH bulb to light it. The heat is incredible with the MH and I haven't tried my HPS bulb out yet. Anyone know if the HPS bulb will be cooler? Also, will it be safe to close the closet? I think on common sense I'm going to have to leave it open and just use a light schedule during the day so I can actually sleep at night lol. Anyways thx for the help, any critiques is helpful too if you just want to throw it out there. Pics: http://i55.tinypic.com/30jtoi8.jpg http://i53.tinypic.com/1499gtv.jpg
600 watts in a small closet... you can try to get a air cooled reflector and a big inline fan to draft the air... you can never have too much light, but you can have too much heat... so.... give the length x width x height of your grow space... this gives cubic feet... multiply that number times three for air movement... and multiply that number by two if you add a carbon filter this gives you the MINIMUM CFM rated fan you need.... figure out a way to get cool air into your grow space or your going to have to build an air chiller...like a tube with tubes running out of it into the path of your intake into your grow... cools the air...
