Profile Porous Ceramics (PPC) particles are 74% pore space with 39% capillary (water) pores and 35% non-capillary (air) pores. Blended with sand in a greens mix, Profile Porous Ceramics improve water- and nutrient-holding capabilities, increase oxygen levels at the root zone, and facilitate drainage when soils are saturated. The particles also hold water and release it as needed to the plant, delaying the need for irrigation.
