Hey guys, I purchased a 'complete' grow system. It is a 250 Watt MH Light. Nowhere in the instructions does it mention hooking up an exhaust fan, and on the website i bought it from, the item mentions no need for an exhaust fan (on other items in the website it says you will need one). However I just hooked it all up, after about 2 minutes of it being on I touched the lightbulb and it was very hot, after about a second it was to hot for comfort. Do I need an ehaust fan for this? I plan on having a small 12 inch or so fan on blowing towards the wall to circulate and simulate a breeze inside the grow closet. What do you think? Here is a link to the lighting system I purchased. http://www.bghydro.com/BGH/customkititems.asp?kc=HLMH02MAX&eq= Sorry about asking so many questions, but this could potentially be a fire hazard if I was wrong and it does need an exhaust fan, but atm I am leaning towards it not needing one. Thanks. Joe.
