Cocogro uses 1/2 inch double-sieved long fibers to reduce dust and give ample air space within the mix. Cocogro has excellent drainage properties and can be used over a longer period of time than coir fiber with shorter fibers. Cocogro's longer fibers create an optimal air to water ratio, which is vital for strong root development. Cocogro is a superior coir fiber because it is aged a minimum of eighteen months and has finished its decomposition stage. In addition, Cocogro is exposed to rain water from at least three monsoon seasons, which naturally washes harmful salts from the final product. Most other coir fibers are only 4 to 5 months old and may have excessive potassium and salts that require chemical treatment.
