Hello everyone!

My boyfriend and I got a ball python last night, and what a sweetie. This is my 2nd snake (I had a red-tail boa when I was a child) and my boyfriend's first snake. I just had a few questions which I wasn't sure of.

Right now, for heating, I have a heat lamp (black light) on one side (for the cooler side which stays around 77-80°) and a basking light on the other. The basking light is proving to be too hot (nearly 100° so I immediately turned it off). This is my first ball python, and my first snake which I am caring for on my own. For the warmer side of the terrarium I am aware it needs to be around 90°. Does anyone have any recommendations as how to keep it around 90°? Would getting a small UTH for the warmer side work better (since I know they require belly heat)?

Any help would be much appreciated!
