Supreme Perlite Coarse Horticultural Perlite for Potting Soil Mixes, 4 Cu Ft Bag

Supreme Perlite Coarse Horticultural Perlite offers a professional-grade soil amendment ideal for gardeners, growers, and plant hobbyists who require superior drainage and aeration in their potting mixes. This large 4 cubic foot bulk bag provides a valuable supply for greenhouses, nurseries, commercial growers, and home gardeners working with multiple plants, raised beds, propagation setups, or specialty soil blends.

This coarse-grade perlite contains large grains measuring approximately 1/2 inch (13 mm) or larger, making it an excellent choice for plant species that require fast drainage and increased airflow around the roots. Its structure helps prevent soil compaction, improves oxygen availability, and supports healthier, stronger root growth. In addition to its large particles, the blend includes fine and medium grains to help maintain balanced moisture retention—ideal for tropical plants, succulents, aroids, cactus mixes, and high-airflow potting blends.

Made from natural expanded volcanic perlite, this horticultural amendment is clean, sterile, lightweight, and pH neutral. It is completely odorless, non-toxic, non-flammable, and asbestos-free, making it safe for indoor and outdoor gardening environments. Whether you are mixing soil for houseplants, propagating cuttings, refreshing container gardens, or building hydroponic systems, this perlite delivers consistent performance and long-lasting durability.
