Substrate Exo Terra Coco Husk 20 L (2.1 kg) — coconut fiber terrarium bedding

Exo Terra Coco Husk 20 L (2.1 kg) is a coconut fiber substrate formulated for use in terrariums and vivariums. The natural coco husk granules hold moisture while providing good aeration and a stable surface layer that supports burrowing and root growth. Designed for reptiles, amphibians and invertebrates, this substrate helps maintain humidity levels in tropical and forest-style enclosures and can be used as a planting medium for live terrarium plants.

Advantages

This coconut fiber bedding offers high water retention and gradual moisture release to support consistent humidity without becoming waterlogged. Its fibrous structure promotes airflow through the substrate to reduce compaction and allow burrowing animals to dig and form tunnels. The material is free of added synthetic chemicals, biodegradable, and provides a natural look suitable for planted and rainforest-style terrarium setups.

Suitable for

• Reptiles that require moderate to high humidity (e.g., geckos, skinks)
• Amphibians and tropical species needing stable moisture levels
• Burrowing species such as certain snakes, skinks and invertebrates
• Planted terrariums as a component of the planting medium

Key specifications

• Volume: 20 litres
• Weight (approximate dry): 2.1 kg
• Material: coconut fiber (coco husk)
• Texture: fibrous granules suitable for burrowing and rooting
• Moisture behaviour: high absorption with gradual release

How to use

Rinse or pre-moisten the substrate according to the enclosure’s humidity requirements, then distribute an even layer across the terrarium floor. Layer depth should be selected based on species needs: shallow for surface-dwelling animals, deeper (several centimetres) for burrowing species and for planting. Monitor humidity and replace or refresh substrate as needed to prevent excessive compaction or odour. When used with live plants, mix with other planting media or soil to improve nutrient retention and drainage.

Usage recommendations

Maintain appropriate humidity by wetting the substrate lightly and regularly rather than saturating it. For enclosures with high moisture demands, combine coco husk with a drainage layer and a moisture-retentive mix to balance aeration and water retention. Replace heavily soiled substrate promptly and refresh in stages to maintain a healthy environment for animals and plants.
