Heat lamps will also suck the humidity right out of the cage and the snake. Under tank heaters are much better.

I would recommend viewing some of the care sheets, they offer great advice, but it sounds like your a bit low on humidity, try misting the enclosure, and monitoring the humidity, or when you see the corn is getting ready to shed, put wet spagham moss in the hide.
