You can also use a good hydrometer for the terrarium. It will help to monitor the humidity levels inside. Keep the humidity between 35% to 40% inside the enclosure but not more than 55%.

3. Create a Temperature Gradient

Make sure to have a consistent temperature gradient all over the enclosure. The hottest area should be on the basking spot. While the coolest must be on the opposite side of the terrarium.
