Hi,

I have just finished setting up my grow room, complete with lighting. I began monitoring temperatures last night. The room stays a pretty constant 75 (50% humid.) unlit, but once the light was on a couple of hours, it raised to 80. I don't know what it will be like once its on 18 hours! Any suggestions to lower the heat that I haven't thought of?

Background:

10 X 10 X 8 carpeted, top floor spare bedroom.

400W MH light

White 6' bookcases 4 feet apart, with the light hanging on chains from a 2X4 above.

Oscillating fan with ionizer running on high.

Black plastic covering window (and I must say proudly, from outside, there is no light escaping at all.)

Air conditioning set to 76, but the thermostat is outside of the room. Any cooler than that would make the rest of the top floor too cold for comfort.

Any suggestions would be super! Thanks,
