Hello, everybody! I'm new here, and have a question. My little brother is getting a ball python on May 12th, and we have already bought the terrarium and the stand for it. Yesterday he bought a "starter kit" which had a bag of substrate, a water dish, a hiding place, a thermometer, and a heating pad. I was wondering, is a heating pad a significant source of heat for a 20 gallon terrarium, or would we be better off with a heating lamp? Thanks for any help you can provide.
