We just bought a ghost hypo ball python from a local pet store today. I had done research previously but the pet store gave me rather conflicting information about what we would need for the set up. I have her in a 20 gallon glass tank with a lid with paper grocery bags as substrate. The pet store said that a nocturnal infared heat lamp would provide adequate heat for her, so that's what I bought-- although I had read previously that under the tank heaters would need to be used? I made a hide for her out of an old plastic flower pot I cut in half. They store said she only needed one hide-- again I had read previously a hide should be on the warm and cool side?
