Coir pith, Organic : Yes

Coco peat (cocopeat), also known as coir pith. coir fibre pith, coir dust, or simply coir, is made from coconut husks, which are byproducts of other industries that use coconuts
Cocopeat primarily consists of the coir fibre pith or coir dust which is obtained by processing coconut husk and removing the long fibres. The cocopeat which is obtained can hold large quantities of water, just like a sponge. It is used as a replacement for traditional peat in soil mixtures, or, as a soil-less substrate for plant cultivation
Coco peat is used as a soil additive. Due to low levels of nutrients in its composition, coco peat is usually not the sole component in the medium used to grow plants.A spongy material that binds the coconut fibre in the husk, coir pith is finding new applications. It is an excellent soil conditioner and is being extensively used as a soil-less medium for agri-horticultural purposes. With its moisture retention qualities, coir pith is ideal for growing anthuriums and orchids.
