My UTH and 24-hr red lens heat lamp are plugged into a thermostat which obviously regulates the temp to where I want it. When the tank becomes the desired, temperature, the thermostat turns off the heat lamp. Normally this isn't really a problem since I still give my BP 12 hours of day and 12 of night with the room light anyway.
Is the heat lamp turning on and off during the night going to bother or otherwise be a problem for my ball python?
