Light Expanded Clay Aggregate (LECA) consists of small, lightweight, bloated particles of burnt clay. The thousands of small, air-filled cavities give LECA its strength and thermal insulation properties.
- Ideal media for hydration for plant systems

Used as our preferred support media for Hydroponics, the base material is plastic clay which is extensively pre-treated. LECA offers you an environment-friendly, entirely natural product incorporating the same benefits as tile in brick form. LECA is indestructible, non-combustible, and impervious to attack by dry-rot, wet-rot and insects.
