Enhance your media with professional horticultural perlite—expanded volcanic glass that increases air space and drainage without affecting pH. Choose fine, medium, or coarse grades for seed starting, plugs, and container production; blend with peat or coco to dial in water‑holding and structure, or top‑dress to limit algae and fungus gnat pressure. Available in 2 and 4 cu ft bags and bulk totes, including select OMRI‑listed options from trusted brands. Shop in‑stock grades for quick local pickup in Fallbrook, and ask our team for recommended mix ratios and pallet pricing.
