Just make a humid hide. Tupperware with a lid on, moss or moist paper towel inside. I guarantee your snake is gonna find it and sit in there till they're good and ready to shed. They're dumb, but they're wired for survival. Snakes and reptiles have been managing their own sheds for millions of years. The only responsibility you have is to give them the option. They possess the ability to seek out a humid micro-climate when they need it.
