Hey guys I have a way to regulate your UTH without a tstat(if you want). But I recommend this not be a permanent fix! Tstats do the job right and this plan should only be used when you don't have a tstat yet, but are getting one. Well what I did was take out the substrate on the hot side and put some toilet paper (you can use paper towel) on the bottom of the tank on top of the UTH, about 2 pieces for me, but it may be more or less for you, whatever works. I then put the substrate back on and the temps were a perfect 93 degrees! Everyone who has a UTH knows that when a UTH goes unregulated it gets to a blazing 130 degrees but with this plan you can get to the temps you need it to be at! You can put more substrate for it to get cooler, or take away some to let the temperature rise. And since ball pythons like to bury themselves under the substrate, your snake won't ever get in direct contact with the UTH. I think this is a way for people who just got their Ball Python to have the correct temps until they get a thermostat. Again, this is not a permanent fix, get a tstat!
