Hi,

Can you tell me more about these thermometers you got? are they digital with probes? If so put the probes inside the hides directly on the glass. Then try them on top of the substrate inside the hides. Leave them for at least 30 minutes (and longer if you can) to let the temps stabilise from you opening the lid and lifting the hides etc.

There is no real reason to measure the temps half way up the sides of the tank really if you can measure where the snake actually spends most of its time.

Have you read the various good threads on modifying the tank lid to hold in humidity and insulating the bottom, back and sides to help hold the heat steady? I really prefer using the foil to cover it rather than the towel as I feel it has less possible problems. The black you put on the outside of his tank will help with his feeling of security but adding a layer of insulating material like polystyrene or cork shetting or reflectix (sp?) will help with heating as well.
