Ball Python Questions- hiding in the cold...

[clmclark]

For the most part I've just been leaving her alone to get used to her surroundings. I've moved her into my bedroom because it's the quietest room in the apartment (sad I know lol).
In her set up I have a warm hide, cool humidity box, water dish and basking vines/branches... She was hiding under the water dish in the coldest spot in in her set up. I swapped out her hollow bottom dish for a flat dish. She then moved to the humidity box. I checked the other day and it's about 72 degrees in there. I'm concerned that she's too cold or that I'm keeping the other side too warm (85). I took out the humidity box to try to get her to move around a bit. She was very active last night. It was nice to hear her on the go... woke up to find her burrowed under her flat bottom water dish...which she successfully did with out spilling any water. I was impressed... should I be concerned that she's too cold? How do I get her to come out of hiding sooner? I'm trying to be patient. I'm I'm harming her or lessening her chances of coming out if I take her out?
