Durable Mesh Barrier – Specifically designed to keep the drainage layer separate from the substrate in high-humidity enclosures, creating a healthy habitat for frogs, geckos, lizards, and snakes.

Perfect for Bioactive Setups – Essential for rainforest enclosures, this mesh barrier helps maintain substrate placement and prevents it from mixing with the drainage layer.

Oversized for Flexibility – Our mesh is cut slightly larger to allow easy adjustment during setup, making it ideal for new bioactive enclosure builders.

Easy to Use – Simply layer your drainage material, place the mesh barrier on top, and add substrate. Suitable for use with bioactive substrates, including our Rainforest blend.

Beginner-Friendly Design – Leave one corner accessible for easy water removal if needed, helping you maintain optimal enclosure conditions.
