Hydrodynamics International - Profit Discs, Bag Of 20

Profit Disks, or as we like to call them, Crop Circles, are made from the highest quality coco fiber from Sri Lanka. Profit Disks are used by commercial growers around the world. Profit Disk coco is more coarse than normal coco and has far more air space within the matrix. When soaked, Profit Disks expand to many times their volume. The 20 disk package with built in handle makes it easy to carry.
