I have a 40 breeder and I'm tellin' ya... moss and wet towels rule!
Both of Furio's hides are stuffed with moss (He likes to nest in this) then all around his hides are and around his little jungle gym thing as well. I mist once every 2 days (pretty thorough) and the humidity stays around 55-56% during shed I mist everyday and it gets up to about 61% and he sheds like a little champ! Hope this helps!
