My flower room has 4x1000 watt hps lights that are aircooled off an inline fan and filter. i have absolutly no way to bring in cold air from outside as this house is poorly designed. I have seen a lot of window ac units for sale on craigslist for good prices. I was thinking about putting the ac unit in the room and running it while the lights are on. Has anyone ever done this and did it work. Also how much electricity do these things use. Thanks guys really appreciate it
