Thermometers must be digital, UTHs have to use a thermostat to keep the temperature from getting dangerously hot. A dimmer switch can be a short term fix for this, especially in the summer. Temperature readings must be at the level and spot the snake is and wants to be. This means that the temp in the hide has to be known. Heat lamps should be on a dimmer switch and temp at the bottom of the tank under the lamp has to be known.
Juveniles feel insecure in a too large of a tank. 2 hides and lots of clutter in the tank will help. Clean fresh water at all times and the right humidity is vital. A thermometer that will also read the humidity is needed for this and the cheapest route.
Knowing all this info helps others help you here plus it is info that helps an owner ensure their snake is kept healthy and safe. Knowing all this and keeping the tank properly is also important so you know that if something happens, it is cause for concern because a vet will want to know all this.
