The non-fibrous, spongy, lightweight, corky material that holds the coir fiber in coconut husk together is coco peat. Coir is another name for coco peat for plants. Its horticultural utility was found in the early 1990s, and demand for the substance has been rising ever since. 

It is a 100 percent organic, natural, and biodegradable substance that was previously a by-product of the Coconut Fibre Extraction process but is no longer the case. It is presently a by-product of the extraction of coconut fiber.

Because coco coir is so environmentally beneficial, one can reuse it. It will function flawlessly again after a quick rinse and strain. When coco peat is compared to soil, the peat stores far more water and releases it gradually to plant roots.
