LECA is a clean, reusable, and inert growing medium made from superheated clay pebbles that expand into lightweight, porous balls—ideal for semi-hydroponic setups, propagation, and soil-free growing.

Naturally pH-neutral and mold-resistant, LECA offers excellent aeration and water retention, allowing roots to breathe while wicking moisture efficiently. It's a favorite among aroid and tropical plant growers looking for full control over watering and nutrients.

Use LECA for passive hydroponics, as a chunky additive in potting mixes, or as a drainage layer to boost airflow and prevent root rot.
