I need to investigate if the under tank heater is removable or not, if it is, I'll use your method definately. Yes I was able to hold her but since it was in a different house, I was just worried about handling her too soon after moving her. About temperatures, right after waking up tomorrow I'm going to the store to buy all the necessities. It's a big store so I should be able to but if I can't find all the optimal things then I'll adapt but mostly -in the temperature/humidity departement- I'll be looking for a thermostat, thermometer, new undertank heating pad, hygrometer and a heating lamp.
Like I said before the previous owner kept a whole room heated so he didn't have a heating lamp to give me and when I went and bought the snake from him, stores were closed so yeah I didn't have any choice but to wait until tomorrow to get all the temperatures stuff. And anyway it's not even gonna be that colder than usual because my room is kind of hot right now. As soon as everything is installed I'll take a picture to show the terrarium as a whole and the temparature regulation setup.
