Nutrifield Hydro Clay 50L Bag 

Nutrifield® Hydro Clay starts with the highest grade natural clay following a strict grading formula and is assembled by a granulation method. By following this process, we guarantee that you get a more consistent spherical shape and size with a more uniform and rigid structure that resists breaking. You get a consistent 8-16mm round shape, made from 100% freshly mined raw clay material free of impurities and ready to use straight out of the bag.
