The processing of coco husks to obtain coco coir involve a series of steps like aging, washing, rinsing, buffering, drying, grinding, grading, and compressing into different size and type of blocks. These steps are necessary to change the physical and chemical characteristics of coco coir and guarantee product quality, consistency and uniformity suitable for plant growing. Without proper processing, coco coir will have an excessive salt content; degenerate and compact resulting in problems with Pythium root rot; and lead to nutritional imbalances especially related to calcium and magnesium deficiencies.
