The Coco Terra Coco Chip Brick Large 12x12x4 inch is a compressed coconut husk substrate brick designed for reptiles, amphibians, invertebrates, and tropical enclosure setups. Once expanded with water, the brick produces a loose, natural substrate that helps retain humidity while supporting proper airflow within the enclosure. Coco husk substrate is commonly used for ball pythons, boas, tropical lizards, frogs, tortoises, and bioactive environments due to its natural appearance and moisture holding capability. The compressed format allows for easy storage and transport before hydration. This substrate is suitable for humid and tropical species requiring moderate to high humidity levels and can also assist with odor control and waste management when spot cleaned regularly. Store unused bricks in a cool, dry location away from moisture. Hydrated substrate should be monitored for mold growth and replaced as needed to maintain enclosure hygiene.
