My RES often likes to sleep on his basking area, but I've moved to a cooler area (in the North East) and am concerned about air temperatures as winter approaches. His water is heated and he has a day basking lamp - but what's recommended as a basking area heating source for nights?
I've researched red and "moon" colored lights as well as ceramic "bulbs" and heated pads, but don't feel I've found a definitive answer on what's best. I don't want to disturb him with light, but also want to make sure he's warm!
Thank you!
