Coco peat, also known as coir pith or coir dust, is a natural, organic growing medium made from the husk of coconuts. Coco peat is a byproduct of the coconut industry. When coconuts are harvested for their water, flesh, or coir fiber (used in making ropes, mats, and brushes), the husk that surrounds the coconut seed is typically considered waste. However, this husk contains a spongy material that can be processed and turned into a versatile growing medium: coco peat.
