I keep moss in both of my BPs hides at all times. I only keep them moist during a shed. Other times I make moist and allow to dry out before making damp again. Works fine. I don't even worry about cage humidity now. Using the moss in the hides as I do gives perfect sheds without any fuss.
I do have live plants so I water them every so often so you misting once a day would equal about the same.
