Hi There! Welcome to the Site!
Ideally you would want to put 2 identical hides in your "Aquarium" style setup. One on the hot side and one on the cool side so that your snake does not have to choose which hiding spot he likes better, instead he will be able to choose which temperature he prefers. Make sure you are using some sort of thermostat on your UTH though as they have the potential to get really hot especially when used on a glass tank. If you don't already have a digital thermometer you should get one so that you know exactly what your temps are
