Mike, thanks for the suggestion. Now tell me if I am thinking along the right lines for the lay box: About a 6qt filled most of the way up with the normal soil/sand mix and an appropriate hole for access. Opaque plastic so she feels secure and thinking maybe a small uth on a dimmer for heat( I don't have an extra t-stat at the moment but I can get one if I need to.), and put the whole thing on the cool end. Now should I put the access hole in the side at the top or should I just put the hole right in the lid? I've never done a lay box before so this should be interesting.
