View Full Version : Help with over heating in grow room!

02-15-2007, 04:43 PM
I have a small sealed grow room of 3lx2wx5h. I am using a 430w with the Maximizer Reflector. I have a 4" 75 cfm axial intake (no ducting) blowing into the reflector. On the opposite side, I have a 105 cfm 4" axial exhaust ducted to the elf filter. The heat inside is between 90-95f (way to hot) and the humidity is between 30-40%. I have to keep the doors open to get the temps to drop to about 80-85f.But then it is no longer a sealed room. I am thinking of two options:
1) I keep everything the same and switch the 430w to a 270w.
2)Purchasing a Cool Tube - 19" reflector and ducting it to the intake and exhaust.

Which would be better?
Are the intake and exhaust fans enough?

Thanks for your help. Ive gone to your pasadena shop a few times and they have been very helpful.

I would buy the cool tube. You are going to need a sealed light to drop the temps. This should drop your temps, just remember that you need a good fan blowing on the tubes at all times.
