Western hognoses need relatively dry conditions — 30-50% is a comfortable range. This may not require any additional work on your part to maintain appropriate humidity levels for this species. However, if you live in a dry climate, you may need to pour water into the (cool side) substrate occasionally to increase ambient and soil humidity levels.

Eastern and Southern hognoses prefer slightly higher humidity — 50-60%, especially when they’re about to shed. Offering a humid hide (hide stuffed with moist sphagnum moss) and mixing water directly into the bedding is a good way to help accommodate this need, but it’s also helpful to keep the substrate on the cool side of the enclosure slightly moistened.

Keeping a pressure sprayer full of water on hand is a good way to provide a quick humidity boost.
