Cocogro® is blended from 100% premium coco coir that has been carefully processed to meet our rigorous specifications. Cocogro® offers gardeners an ecologically responsible and superior performing alternative to sphagnum peat-based mediums. Cocogro® has excellent drainage properties and can be watered frequently while naturally maintaining optimum air to water ratios. The high cation exchange capacity of Cocogro® enables it to retain essential nutrients in the root zone until the plant needs them most.

Cocogro has a very low salt content that is available in 3/4 in double-sieved long fibers to reduce dust and give ample space within the mix. It has excellent drainage properties and can be used over a longer period of time than coir fiber with shorter fibers. With longer fibers and reduced dust, growers will experience an optimal air to water ratio.
