I’m currently new to owning a ball python snake. I purchased my snake when it was a hatchling, and during the summer I’d no problem with temperatures. Now since the season has changed (winter months) I’m having difficulty keeping my cool side warm. My snake enclosure is a 40 gallon breeder. My ambient day time temperature will not go any higher than 75 degrees, but the basking side is at its correct temps all the time. I recently bought an under tank heater to see; if this can help raise the heat on the cool side. As of right now I’m using a 75 watt basking light, and for night I usually use a 50 watt red bulb from zoo med. Should I continue with the basking light as well with the under tank heater during the day, and for night what is better the red bulb, or just the under tank heater? Thanks for the help!
