Hydroponics Clay Pebbles Lightweight Expanded Clay Aggregate
Title Introduction
Lightweight Expanded Clay Aggregate (LECA), also known as lightweight ceramsite, is a versatile material renowned for its unique properties and wide-ranging applications.
LECA (Lightweight Expanded Clay Agrregate) is made from the raw materials of clay balls through high temperature firing in a rotary kiln. LECA is a growing medium, which widely used in horticulture and landscaping; LECA is a lightweight, corrosion resisting, heat/fire/moisture/sound-insulating filling material which is widely used in construction.
