Create the ideal foundation for semi-hydroponic growing or improve water retention in your soil mixes with Soil.Ninja Clay Pebbles 10L. Also known as LECA (Lightweight Expanded Clay Aggregate), these small, lightweight balls are designed to wick water upwards, allowing a small reservoir at the bottom of a semi-hydro pot to hydrate the entire root system. Their porous structure also provides excellent oxygen flow to roots, encouraging strong, healthy growth and vibrant foliage.

Clay pebbles are incredibly versatile, working equally well as a standalone growing medium for semi-hydroponics or as a soil amendment to boost water retention and aeration. Long-lasting, reusable, and pH neutral, they’re a practical choice for houseplant enthusiasts seeking a clean, low-maintenance solution for optimal root health.
