Honestly Aslong as your room humidty it 50%+ just spray them once a day during shed and it should come out just fine. My babies <500g on paper get misted once a day during shed (i dont put water of heat tape as it causes buildup on the roof of the rack with the ARS i want to try to keep it from getting any rust!)
But the bigger ones on CoCo husk, get a fresh moist husk during shed, and i let it dry out as they finish shed, Re-moisten it when they going into shed again. Been doing this for a few months (since my ARS) have had a clean smooth shed every time!
Aswell every week the ones on paper get a nice mist when doing clean/new paper so that keeps humidty in good range.
