Temperatures

I'm so sorry if these post are getting annoying. I just spent the last couple of days messing with my tank and trying to fix my temperature issues. My tan currently sits at 83 ambient air and 77 under the tank on my cool side. It is 94 under the tank and 78 ambient air. Are these ok? I have my CHE on my cool side. Its only 100 watts would a 150 watt bulb help?

Yes those are fine.

My personal ranges I am happy with there are some debate on this most of my suggestions are based out of few have accurate thermometers and these temps allow for a 2º error that most afforadable thermometers have.

Typically 77-81 cool side surface
89-92ºF Warm side surface (small snakes can be kept cooler, during digestion they generate heat and it can effect the temps in the hide)
77-85º ambient air temps
