Leca Clay Pebbles 10L Bag

Description

A Versatile Casing & Drainage Layer

Leca (lightweight expanded clay aggregate) pebbles are a sterile, reusable option for improving drainage and moisture regulation in substrate setups, and can be used as an alternative casing layer to vermiculite in some grow configurations.

This 10L bag gives you enough for several batches, and the pebbles can be rinsed and reused between grows.
