The Coco Disk is a disc of compacted coco fiber, a very successful and innovative growing medium. This commercially endorsed growing medium from Holland is the recommended growing medium for the IGS hydroponic system, but they are an ideal option for almost any grower using coco. This product is much coarser than normal coco and thus has far more air spaces within the matrix. It expands when water is added and can be broken apart for easy distribution among nursery pots.
• Each disk fills a one gallon container.
• Dimensions of compressed disk 5" diameter x 1½" thick
