LECA Reusable clay substrate for hydroponic and semi-hydro growing LECA (Lightweight Expanded Clay Aggregate) provides excellent aeration and consistent moisture for plant roots. I deal for semi-hydroponic setups, propagation, and reducing the risk of root rot. Ingredients:100% expanded clay pebbles How to Use:Rinse thoroughly before use to remove dust. Use alone in semi-hydro systems or mix into soil blends to increase aeration and drainage. Care Tip:For semi-hydro use, keep the water level just below the roots so they grow into the moist zone — never let the entire pot sit submerged. Show more
