Good point. Since the heat is less direct even variations in room temperature shouldn't affect it that much, especially since I've got a piece of cardboard covered with aluminum tape over half the cover. That should help maintain the temp in the tank. I'll be snagging some black fiberboard over the next couple of days to cover the back and sides to help insulate it some more.
