I have a mesh screen top for her tank so keeping it humid is a bit difficult, I mist her a couple times throughout the day; I do my best to keep it at 60%-70%.
By shed box, I mean I have a tub that I put a damp, warm towel in and I put her in it and let her stay in there for about 15 minutes. I don't have a humid hide, I have one on the cool side and one on the warm side.
