The basic material in Leca Flower Hydro Clay Pebbles is a lightweight, aggregate bold clay.
It is burned in rotary kilns where the clay is expanding into small 'pebbles'. The firing process removes all excess organic material. The hydro clay pebbles consist of thousands of tiny air cells within a hard shell of baked clay.
Leca Flower Hydro Clay Pebbles can be used in the bottoms of pots and containers providing a natural moisture balance and helping prevent overwatering.
Leca Flower Hydro Clay Pebbles can be used by themselves or with soil.
