I've read several care sheets and they all say you need some humidity and that your snake will shed (duh) but there are no specifics?

I can't find how high I need to keep the humidity or how it's achieved. Just a misting bottle? Do you try to avoid spraying the snake?

From being on this forum it seems like shedding is an accomplishment. Does that mean shedding does not happen often? Do you need to pay extra care to your snake when it is shedding?
