im thinking the swamp cooler would be better if you live in a dry climate, it is so much cheaper to run. I have a Master Cool "swamp cooler" for my home, and its not humid in here, and my bill isn't bad
most a/c's will run more watts then 400hps lights, and just start to add more kilowatts to your electric bill. I think if you live where it gets humid, down south or east coast a/c is your only option
