Supreme Perlite Coarse Horticultural Perlite and Medium Horticultural Perlite

This package of Supreme Perlite Horticultural Perlite in Coarse & Medium (4 Cu Ft Bags) provides professional-grade soil amendments designed to improve aeration, drainage, and overall plant health across a wide range of growing applications. Whether you choose Coarse Perlite for maximum airflow or Medium Perlite for balanced moisture retention, each 4 cubic foot bulk bag delivers consistent quality for greenhouses, nurseries, commercial growers, and dedicated home gardeners.

Supreme Perlite Coarse features large particles measuring approximately 1/2 inch (13 mm) or larger, making it ideal for plants that require fast drainage and high oxygen levels at the root zone. Its rigid structure helps prevent soil compaction, increases airflow, and supports strong root development. The coarse blend also includes some fine and medium particles to maintain workable moisture balance, making it well suited for tropical plants, aroids, succulents, cactus mixes, and high-airflow potting soils.

Supreme Perlite Medium contains a blend of fine and mid-sized particles, typically around 1/4 inch (4–5 mm) or smaller, offering an excellent balance of aeration and water retention. This size is ideal for potting soil blends, seed starting, propagation, raised beds, hydroponic systems, and container gardening, where consistent moisture and root support are essential.

Both grades are made from natural expanded volcanic perlite and are clean, sterile, lightweight, and pH neutral. They are odorless, non-toxic, non-flammable, and asbestos-free, making them safe for indoor and outdoor use. OMRI Listed for organic agriculture, Supreme Perlite products meet strict organic standards and deliver reliable performance for every stage of plant growth, from seedlings to mature plants.
