yeah i forgot to mention that it will get pretty warm, and if it's in a small area you will for sure need some ventilation. But I got away with using a regular house fan with a 1000watt system, just made sure it didn't get too hot where the plants were, and had air always blowing in there for circulation and to keep it cool. Beats paying out the bung for ventilation stuff...i would have had i really needed to but it worked good with the fan from wallyworld.
