Supreme Perlite Coarse Horticultural Perlite for Potting Soil, Gardening, Seed Starting, Propagation and Soil Aeration, 4 Cu Ft Bag

Support healthier plant growth with Supreme Perlite Coarse Horticultural Perlite, a versatile soil amendment designed for gardeners, growers, and plant enthusiasts who need improved drainage and airflow in their growing media. This large 4 cubic foot bulk bag supplies ample material for greenhouses, nurseries, raised beds, propagation projects, and home gardens where consistent soil structure matters. It is well suited for anyone managing multiple plants or creating custom potting mixes. This coarse-grade perlite features large particles measuring approximately 1/2 inch (13 mm) or larger, making it especially useful for plants that benefit from fast-draining soil and increased root-zone airflow. The coarse structure helps reduce soil compaction and allows excess water to move away from roots more efficiently. Alongside the larger particles, the blend includes a range of medium and fine grains that assist with moisture balance, helping soil retain enough water without becoming saturated. This combination works well for succulents, cacti, tropical plants, aroids, orchids, and other species that prefer well-aerated growing conditions. Supreme Perlite is produced from expanded volcanic perlite and is clean, sterile, lightweight, and pH neutral. It is odorless, non-toxic, non-flammable, and asbestos-free, making it suitable for both indoor and outdoor gardening environments. The lightweight nature of perlite also helps reduce overall soil weight in containers, making pots easier to move and manage. This coarse horticultural perlite can be used for potting soil blends, seed starting, propagation, hydroponic systems, and specialty plant mixes. It is also OMRI Listed for organic agriculture, making it compatible with organic growing practices. Whether you are building custom soil blends or improving existing mixes, this bulk perlite offers a practical solution for managing drainage, aeration, and moisture balance.
