I haven't had shed issue's yet. I know that if you get bad shed's your humidity needs bumped up immediately. There are just different ways to keep the temps where they should be without UTH. I have a friend with a insulated room that is in his garage on a thermostat that is set at 85 degrees. He houses many snakes and never has a problem at all. No belly heat just heat lamps in the room. He has a humidifier in the room and the humidity runs between 50% and 60% most of the time and he can bump it to 70% at max. Never has any problems with anything either. Like I said there are several ways to do things. I like it best when people give options on how they do things. There is no 1 way that things have to be done in this hobby.
