Thank you to everyone.No,I put the heat lamp on the outside of the screened cover. I feel like a new mom. I worry. Hopefully, it was the bedding. I'm going to get him a new substrate anyway. I'll put some more nature type pictures on the outside of his place.I feel better to have people to chat with about python care. Thanks again, I'll keep posting to let you know how it's going and ask questions
A good plan for your substrate is this, put him on papertowels or newspaper and if this liquid appears again TAKE PICTURES!
Then for future substrate, aspen is a good wood base you can use.
