HY-GEN COCO GROW is a vegetative stage coco-peat specific nutrient. Coco grow contains a natural kelp extract to condition the coco-peat while stimulating and maintaining a healthy root system. It also contains additional calcium, which is essential during the late growth stage to ensure a high number of flowers are produced and retained by the plant. A lack of calcium can lead to a large number of flowers aborting before they can transition into the fruiting stage. Calcium is commonly used in the commercial coco-peat buffering process to improve coco-peat quality.
