My son got a 4.5m old Ball Python a couple of weeks ago. It is our first. With trial and error we finally got a good cage set up. We live in an extremely dry area so he is on Eco-earth and Forest floor mixture to keep the humidity around 60%. My question is does the thermometer probe go on top of the substrate or below it against the glass? We have a UTH unit and Infrared at night as our temps just dropped.
Thanks
