69 is fine. Just wanted to bring up mold since you mentioned that you keep spraying the paper bag and soaked mulch. I think everyone worries when they start out. Then you realize how bombproof these reptiles are and you start worrying a lot less. With my PVC enclosure setup, sometimes I don't check up on them for days. Everything is set up on thermostats and alarms are programmed in case the temps are either too high or too low.
