Get the humidity up to 70% (if possible) in the tank). However, if your BP makes use of the humid hide you've made, then you more than likely don't need to worry about the humidity in the rest of the tank.
Make sure your BP has something rough to rub on to get the shed started - like a branch, log, etc.
Some will eat while in shed, some don't. If you do try to feed while in shed wait until the eyes clear up. Once they clear up your snake should shed in the next few days. I prefer to wait to feed until after since they are usually pretty hungry then - and that way you don't risk wasting the prey if they don't eat it.
Don't handle or disturb your bp during this time. Shedding can be taxing and stressful for them.
Once he/she has shed, check the shed and the snake to be sure it all came off - particularly the eyecaps.
Best of luck!
