Supreme Perlite Medium Horticultural Grade Expanded Perlite – 4 Cubic Foot – 113 Liters – 103 U.S. Dry Qrts – Indoor & Outdoor Use – OMRI Listed

SUPREME PERLITE Coarse Propagation Grade perlite consists of large, medium, and fine perlite grains intended to provide balanced drainage and moisture holding capacity. An excellent propagation medium on its own, it is also useful as a soil amendment, and conditioner for soilless growing media. Mix with coconut coir, peat moss, or other growing media to make a high quality potting mix. Perlite is a 100% natural, heat-expanded siliceous volcanic rock. It is used to loosen heavy soils and as a medium for seed starting and root cuttings. Perlite is, sterile, ultra-lightweight, non-toxic, permanent, incombustible, asbestos-free, and virtually pH-neutral. Our agricultural and horticultural grade products are listed with various standards organizations for organic agriculture including the Organic Materials Research Institute (OMRI) and the California Department of Agriculture’s Organic Input Material Program (CDFA OIM). Organic certification ensures that our products are free of contamination from heavy metals and pathogens, and produced to the highest standard of purity and quality.

• Horticulture Grade Perlite - Horticultural grade perlite is derived from a naturally occurring, volcanic rock. When furnaced at high temperatures, perlite “pops” and expands up to 10 times its original volume. The resulting, lightweight particles are made up of microscopic spheres with a porous, irregular surface that stores moisture and promotes plant growth.
• Our perlite products have proven themselves as a consistent growing media for horticulture because they improve the characteristics of every organic material they are mixed with including peat moss, compost, bark, coir, or in native soil. Horticultural grade perlite is stable and will not degrade or compact over time. It maintains consistent aeration and drainage for plant roots and will not decompose or deplete nitrogen levels in the soil.
• Adding perlite to soil and growing media lightens the soil and introduces pore spaces that allow air and water to penetrate the root system. Excess moisture is permitted to drain out and maintain balanced air and moisture conditions which contribute to healthy biological and microbial activity, and minimize the chances for rot.
