Coarse Perlite is a lightweight, highly porous volcanic mineral designed to significantly improve drainage and aeration in potting mixes. With its larger particle size, it creates air pockets within the soil, allowing excess water to drain freely while promoting strong, healthy root systems.
 
Ideal for plants that require excellent drainage, Coarse Perlite helps prevent soil compaction and reduces the risk of root rot—making it especially useful for succulents, cacti, aroids, and other sensitive plants. It is also well-suited for carnivorous plant soil mixes, where a low-nutrient, free-draining medium is essential.
