LECA (Lightweight Expanded Clay Aggregate) is a popular, highly versatile growing medium. It retains moisture while allowing excess water to drain efficiently, supporting healthy root development. Commonly used in clear containers or vases for propagation, LECA makes it easy to monitor root growth. Simply add water to cover about one-third of the LECA and place cuttings directly into the medium.
Also suitable as a decorative topper to give plants a distinctive desert or Mars-inspired aesthetic.
