Another thing is you probably don't need the heating lamp, because the uth will generally do it's job, and because snakes like ball pythons profit more from belly heat than from back heat (so heat they absorb from the ground and not heat from the ambient air), it helps them digest better.
Secondly, 100 is way too hot for a bp, the max it should ever get is 93 or 94. Thermostats are one of the most important herper tools, and as was said before, you don't need to switch the heating things during the day/night and you don't need to soak your snakes unless there's a problem.
