I think you mean thermometers? Keep in mind that your dimmers do not adjust for ambient temp changes in your house. In winter it isn't too bad but come summer time your guy will be cold. You might have to adjusts just about every time your a/c cycles.
Don't know what "store" you worked in but none of them that I know of run belly heat, they relay on lighting to heat their animals. They have no clue about what humidity is for either much less anything remotely close to care for any of the animals they sell. Some get it and some never will.![]()
