wow, you guys hooked me up with some great advice! here are my exact specs and everything. i am growing in about a 2x2x5 foot closet, in a spare bedroom in my place. light stealth is not an issue; smell inside is not an issue, but outside possibly could be. i try to keep the closet pretty much open during the day to keep temps down and to keep good ventilation. i am renting, so major modifications are not possible (minor ones maybe, i already screwed up my security deposit). i have a window about 7 feet away from the closet. my budget right now is at about 100 dollars, but next month i could spend a couple hundred. i just bought a hundred dollar window A/C from wal-mart, but it isn't even cooling the room too well. i bought the econo-wing reflector (batwing style), so cooling the lamp isn't much of an option. any further advice would be much appreciated! thanks guys!
