Son getting ball python. Cage setup help please

[Kaorte]

Well for the tstat u guys say dont put it inside the cage but put it between the glass and the uth.. How can i do that if its stuck to the bottom?

It is not REQUIRED to put it between the UTH and the glass. I never have and all my enclosures are just fine. Just make sure the probe is securely taped to the bottom of the UTH. Aluminum tape works the best for this.
