Nothing wrong with 85 F. ...But as summer gets here you may see a problem of elevated temps in your room. You need to start now implementing some sort of a/c to cool off your room. You said nothing about having any air cooled hoods,.. If your don't, then you should think seriously about doing this. I have 6 x 600w in a 8 x 12 flower room with cool tubes and my temps w/ lights on hover around 75-80
