I am purchasing a 35x23x12 plastic cage from repti-racks for a male ball python. The room where he will be kept will be around 78 during the daytime, but the nighttime drop will be in the upper 60's-low 70's. When winter comes [Nov/Dec] the nighttime temperature might drop into the lower 60's. I can't have the room heated so I was wondering if it is ok to use both a radiant heat panel and underbelly heat used in order to maintain the hot spot and ambient temperature [or do I only use on,if so which one]. Of course they will be controlled with a thermostat and the proper wattage of each heat source will be used.
