So I just set up 4 clones in a 3x3x6 growtent. First off the temperature is down to 82*F (down from 90 when i first set up!). I have the front open, and the top pulled back so it is open around the ballast. Any suggestions for how to get the temperature down further into a more suitable range? I am using one fan now, I plan to get another tomorrow. Currently they are under a 150W metal halide, but that is a borrowed bulb and i need to get a new one. SHould i get another 150W or something different? the Power adapter for the ballast has a home made sticker on it that says 400 watt HPS, but i don't know what that is from as i bought it used. I was planning on buying a 400W Metal halide, but the temperature is already so high.. Will using a 400W bulb make it much hotter? Any suggestions, comments or tips would be appreciated this is my first grow and first post. Thanks in advance.
