You can use anything for a hide or buy some online reptile basics sell nice ones, I'm currently using what Walmart sells as a salsa bowl its plastic I just had to make an opening, but you don't want to keep on side wet your snake could get scale rot or a respiratory infection from too much humidity, Walmart sells a thermometer made by accurite it has a probe and measures indoor and outdoor temp reading so for your tank hot side and cool side it also measures humidity, and if you have room you can leave the half log in there, and you need 2 identical hides one for hot side one for cold
