LECA - Light Expanded Clay Aggregate Growing Medium - Leca Red 8-16mm granules

Product Description

Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a light weight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure. LECA has an approximately round or potato shape due to circular movement in the kiln.
