I do. I'm in south florida, so for about 8-9 month of the year I just open the snake room windows. It's always python weather. In the winter I go with an oil filled heater on a ve-300 tstat and close the windows.
I am in the same area. I have been doing this the hard way for way to long. Going to block the room off like Deborah said so I can keep the rest of the place under air.
