i have a grow box in some room in the garage. Its a transparent container that i painted white on the inside, and then hooked up 2 bathroom light racks each with 3 spots, and a hundred watt max per spot.

so 600 watts of light, and in 60 seconds the box goes from 60 degrees to over 160. (thermometer can not read past 160).

i am using 100 watt full spectrum light bulbs

i am going to attach a pc fan for exhaust to the box but i really dont think it will help that much.

the box is an oven.

What do i do to lower the temperature?

Thanks
First thing is you need to get rid of those incandescent bulbs and get yourself some CFL's (Compact Flourescents).CFL's are a lot cooler running, you'll notice a temp difference just changing them out. You are getting so much heat for two reasons. The incandescent bulbs are creating massive heat and you have little or no ventilation. You ned to be able to bring fresh air in as well as exhaust the heated air out.:thumbsup:
