The Exo Terra Wet Log Ceramic Hide is a moist hide designed for reptiles, amphibians, and invertebrates kept in vivariums and terrariums. Built from hygroscopic ceramic, it creates and sustains a humid microclimate passively — no spraying schedule required. Available in a range of sizes to suit different species and enclosure setups.
Why a Moist Hide Matters
Reptiles without a secure, humid retreat are at risk of chronic low-level stress, which directly affects appetite, behaviour, and long-term health. A dedicated moist hide addresses this by giving animals a sheltered space where temperature and humidity remain stable — conditions that support natural thermoregulation, hydration, and a clean shed.
How the Ceramic Works
The ceramic construction is hygroscopic, meaning it actively absorbs water from the built-in reservoir and releases it gradually into the surrounding air. This self-regulating process buffers the microclimate against the sharp humidity and temperature swings that can occur in a terrarium, maintaining steadier conditions without keeper intervention. Adequate air humidity levels also support respiratory health.
Egg-Laying and Breeding Use
The internal chamber is well suited as an egg-laying site. Adding moistened moss — forest moss or sphagnum moss both work well — creates the warm, humid conditions that many reptile, amphibian, and invertebrate species require for successful egg deposition and incubation.
Maintenance
- Keep the water reservoir filled at all times to maintain optimal microclimate conditions
- The ceramic material self-regulates humidity release — no manual misting of the hide interior needed
- Compatible with any terrarium substrate or layout
- Easy to remove and clean as part of routine enclosure maintenance
Choose the size that suits your animal's species and the scale of your enclosure — the variants are listed above. Giving your animals a stable, secure humid hide is one of the most straightforward husbandry improvements you can make.
