Your heat problem may not seem like big problem now but it will get worse as your plants get taller. The tops will get closer to the HID metal hallide and begin burning them, and your plants may wither as they get taller. A ducting system will be needed and asap. You should get make a system with an exhaust fan and a can carbon filter. As for your growing oder problem, you should buy an ionizer and air filter. Also get an air freshener that spreads oils in the air (like glade plugins). Better yet get the ones that spreads ether oil, those nuetralizes oders much better.
Dimebag Reviewed by Dimebag on . Couple of Questions, heat, ducting etc. I just got a 400w metal halide. My closet is about 3x4x7. It is definatly enough light in there now. My plants are all about a foot tall give or take. Heats somewhat of a problem. Right now it's 88.3 and it's gotten up to 90.5 As long as it dosn't go over 90 I'm not too worried, but I'd really like it in the lower 80's. I have one fan in there circulating air, and thats it. I can't really have an exhaust fan. The attic is right above my room, maybe I could cut a hole up there and duct it Rating: 5
