Coco husk is available in various forms, such as blocks, pellets, and loose fibers, and can be used in a variety of gardening and agricultural applications.

In addition to its use as a growing medium, coco husk can also be used as a soil amendment, mulch, animal bedding, erosion control measure, and to make biodegradable pots. Overall, coco husk is a versatile and environmentally friendly material that has numerous applications in sustainable agriculture and horticulture.
