Indoor Heating problems?

[longhair]

I know I am going to have heat build up problems soon. I have a 12x12 grow room with one door and one standard window,two 400w hps lamps with at any one time up to 20 plus auto's going,with the winter season now I run between 75 to 83 degrees in heat and 50 to 60 degrees humidity at all times with the door open.When the warm weather comes soon I'll be in trouble.I can't connect my lights togeather to a fan to exhaust the heat outside without cutting a 6" hole in the wall to the outside,not very stealth or a easy idea.How about a 5000w window airconditioner? Will that work?,plus it will look normal from the outside,any ideas will be helpful,Thanks

Sure, an A/C unit will work fine. Even if you did vent outdoors it still might not be enough and would likely need the A/C anyway. But if you did want to try just venting, you could install a clothes dryer vent. I doubt that would raise any suspicion.
