Crested geckos need substantially more humidity than leopard geckos. A useful general target is about 50–70% relative humidity, measured with a hygrometer.
How do I keep crested gecko humidity up?
Regular misting and a suitable moisture-retaining substrate can help, but good ventilation is still important. The goal is humid—not stagnant and constantly waterlogged.
Do crested geckos need a humid hide?
A hide with damp moss or another suitable material can provide an extra humid microclimate, particularly around shedding.
