Expanded Clay Pebbles (LECA) – Bioactive Drainage Layer

Build a strong, healthy foundation for your bioactive vivarium with expanded clay pebbles (LECA)! Acting as the ultimate drainage layer, these lightweight, porous clay balls prevent waterlogging at the bottom of your enclosure, keeping your substrate fresh, aerated, and free from stagnant water.

By separating excess moisture from your bioactive soil mix, LECA protects plant roots from rot while providing an ideal subterranean habitat for beneficial micro-organisms and cleanup crews to thrive.

Highlights:

• Essential Drainage: Creates a dedicated reservoir space beneath your substrate to catch runoff and prevent sour soil.
• Highly Porous & Lightweight: Maximizes surface area for beneficial bacteria without adding unnecessary weight to glass enclosures.
• Reusable & Eco-Friendly: Naturally inert, non-toxic, and easy to rinse and reuse across multiple setups.
• Humidity Helper: Retains residual moisture in the base to help maintain natural ambient humidity in tropical and semi-tropical habitats.

Product Specifications:

• Material: 100% Natural Expanded Clay
• Pebble Size: Approx. 8–14 mm (standard medium grade)
