Coir is the fibrous material of the coconut fruit. The short fibres and dust/pith are by-products of the coconut fibre industry and are suitable for use as a growing media in horticulture, as it has the following benefits:
Coir is a completely homogeneous material.
Texture is consistent and uniform.
Retains moisture well as it is composed of millions of capillary micro-sponges that absorbs and holds up to nine times it’s own weight in water.
Has up to 27% of easily available water.
Holds and releases nutrients in solution over an extended period of time without re-watering.
Maintains an excellent air filled porosity (18%-23%).
Has a natural pH of 5.7 to 6.5.
Has a naturally high lignin content which encourages favorable micro-organisms around the root zone.
