^ Yup! Higher humidity can be tolerable as long as there is no real moisture causing condensation in the bin or wetness on your substrate. - - If your humidity is high enough that moisture is forming molds and/or fungus you can be pretty sure that you have a breeding ground for bacteria and this is obviously not good for your snake.
In my racks my humidiity averages 70% now and I have a snake or two that still need a humidity boost for a clean shed.
