Temperature/humidity control for Ball Python enclosure?

A good temp for ball pythons is between 80 and 90. So the temp were you live is perfect for them, you might not need a lamp at all. Pythons are cold blooded so they use ambient heat to warm up. A snake knows when its needs to warm up and cool down, all you need it to provide an area for both. Put a thermometer on both sides of the tank, keep one side warm,mid 80s to high 90s, and the other cool mid 70s to mid 80s. so since your room temp is in the 80s 90s, what you should do is put a hide in the corner of your tank, and put a heating pad underneath it. That should make the hides inside temp about 5 to 10 degrees higher. When you get your snake, after a few days when it settles down, keep track on wich side it stays on. If it's always in the warm hide, it might be too cold in there, and vise virsa for the other side. Even if the temp is just right, it might not switch sides that often, sometimes spending a whole day on one. Keep an eye on it for a week, then make any changes neccesary. Fake gr, not a good substrate, Aspen snake bedding is no doubt the best, its soft, safe, and lets the snake borrow if needed, but not the only choice. News papers. paper towels are a cheap way to go, there's also a type of reptile "astro turf" product that works well, I forgot the name of it though. Plastic containers are usable, but not the best choice, as long as its big enough for the snake and the lids stays on well, but DO NOT use heating pads on them, they'll melt. I would highly reccomend a aquarium tank, atleast a 20 long. They even make tank just for reptiles, look for them at a pet store.
