Lightweight Expanded Clay Aggregate (LECA) – Moisture & Drainage for Propagation LECA (Lightweight Expanded Clay Aggregate) is a versatile, inert horticultural medium prized for its ability to retain moisture while providing exceptional drainage. Ideal for hydroponic setups, cuttings propagation, and as a decorative soil topper, LECA helps reduce root rot and promotes rapid, healthy root development. Key Benefits of LECA Moisture Retention: Porous clay balls hold water at the root zone for consistent hydration. Superior Drainage: Prevents waterlogging by allowing excess moisture to flow away. Propagation Powerhouse: Use in a clear vase with water at ⅓ height to watch roots form and know exactly when to pot up. Versatile Uses: Perfect as a bottom drainage layer, top dressing for a desert or “Martian” aesthetic, or full hydroponic medium. How to Use LECA Propagation: Fill container one‑third full of LECA and add water until just below the top of the balls. Insert stem or node cuttings—roots will form visibly in days. Drainage Layer: Place a 1–2 inch layer at the bottom of any pot to improve airflow and prevent sitting water. Top Dressing: Scatter LECA on soil surface for moisture control and a unique, modern look.
