I have that very same tub for my young Burmese python (not for long, lol). Very secure, but you definitely need to make a few ventilation holes because the lid is so tight and has a sealing gasket. For a ball python it should be good for a while, although the height is definitely going to be an issue before long, they don’t really Need to climb too much but the young ones definitely will climb if you give them the opportunity. You’re definitely not going to be able to use a radiant heat panels or any type of overhead heater, so you’ll need a heating mat or tape, in that case you put me thermostat probe between the tape and the tank, that is to say outside of the tank so you were measuring the temperature of the heat pad not the temperature of the floor of the tub. Well before you actually get a snake, start “dialing in” the heat pad, use a Temperature gun to take instant readings of the floor temperature compared to the thermostat’s reading of the heating pad temperature. The heating pad will always have to be hotter than your intended floor temperature. So if you want the floor to be 82°, you may not achieve that until the heating pad is 95 or higher, that is the purpose of the dialing in, to see exactly where the heat pad needs to be to achieve the floor temperature – then you set your thermostat to hold that heating pad temperature and of course use a thermometer to monitor on the inside temp of the tub as well.
