4 oz of LECA Hydroton

Hydroton is a lightweight expanded clay aggregate (LECA). Made of clay and ecologically sustainable. Size ranges from about 1/4" - 5/8". The clay pellets are fired in 1200 degree rotary kilns, causing them to expand and become very porous.

LECA is pH neutral and reusable. They are excellent for hydroponic growing, soil amendments, orchid media, and other horticultural uses.
