@Ms Biddy the joys of the old farmhouses. I have mine in the upstairs guestroom of our old farmhouse. in the summer its at 70-80 range and I noticed that if I keep a fan going in the room the air movement seems to keep it right so that it doesn't go above. its winter here already (north dakota 8" of snow on the ground

) I have a cardboard box cut down that it sits in and I keep a towel over it as its in the 60-70 range but sometimes drops below that at night. it seems to be holding steady but this will be my last hatch till spring.
