Millions of Brilliant Little Micro Sponges
Uniform in texture, coir is a completely homogenous material composed of millions of capillary micro-sponges that absorb and retain both moisture and odor. It is widely used throughout the horticultural, industrial absorbent and bio filter industries.
Pictured is coir at 350X magnification. It is estimated that the surface area of coir material to be approximately 0.6ha (6000 square meters) in a single litre of coir. The large surface area is created by the hollow channel structure. This is how it can absorb and retain up to 4 times its own weight in liquids.
