One and a half year old snake, 50 grams?

What are you using to regulate and measure your heat sources?

A petco temperature reader on the right wall of the cage (cool side during the day and hotspot during the night)
A zilla humidity and temperature gauge in the center
A temperature gauge strip on the left wall of the cage as well as on the right.

I'm not using anything to regulate them, money is tight at the moment.
