The coco fibers provide a lot of air and little water, ideal for plants in nutrient solutions. The growing substrate is ecological and is produced by light composting. It is suitable as a replacement for Rockwool and can be mixed with various fertilizers. Coco-Mix helps to maintain the optimal air-water ratio.
