For my ball python, during a normal day we keep the glass terrarium around 55-65% humidity and ambient temp of 26-30C, but a basking spot at 92C. But one end of his cage is cooler and if humidity is too low he sticks to that side. During a shed I bump humidity to 70-75%. He has always had a clean shed and I've never actually seen him soak, not even during a shed. I've never heard of a ball soaking all day so I'm not sure.
