Ceramsite
Ceramsite is a lightweight, porous spherical particle produced by firing materials like clay or shale at high temperatures. Its internal porous structure makes it lightweight, high-strength, with excellent water retention, aeration, and thermal/acoustic insulation. Our ceramsite for plants is available in a full range of sizes, from 4-8mm to 15-25mm, for various applications. Widely used as lightweight aggregate in construction and as a soilless culture substrate, drainage layer in pots, and base layer for green roofs in horticulture. As a growing media, ceramsite supports roots while storing moisture and nutrients, effectively preventing root anoxia and rot. It is an important material in modern vertical greening and protected agriculture.
Expanded clay pebbles are lightweight, round particles made from high-quality clay through high-temperature sintering and expansion. They have a honeycomb porous structure, are hard, and have stable physical and chemical properties. They are an environmentally friendly inorganic substrate for horticulture, potted plant care, and landscaping, and have multiple functions such as breathability, water filtration, fertilizer retention, and heat insulation.
