What is coco coir? 

Coco coir is simply the extracted husk fiber of a coconut. When used as a growing medium, coco coir is a suitable substitute for peat moss.

How Is Coco Coir Made? 

Coco coir is made by soaking part of a coconut in water for a long period of time. The piece of the coconut that is used is the "husk" or the fibrous middle area. Following the soaking process the husk is dried or "cured" for 6-12 months. This dried husk is then processed, sliced into thin chips or ground into tiny pieces, before it is usable for agricultural purposes.
