Too much light??

[lampost]

WAYYYY TO MUCH LIGHT! at the most get a 400 watt.

Also, if you dont want to burn the house down, get one of these....BetterGrow Hydro Online - Flame Defender Automatic Extinguisher

If you can keep the temps down, then there's no problem with a 1000W. You'll definitely need to go air-cooled, but if you have means to vent the air then go for it. You'll yield A LOT more and if you're gonna do it.... go big man!!!

I've seen a 1000W in a 4x5' room and it works great with an air-cooled hood and a nice fan..... cost you an extra $100. You can get some great 6" fans for about $100.... check out HTG. The $25 inline may even work for you if conditions are right.

The more light the better!
