PVP Super Coarse Horticultural Perlite - 4cu ft

• Perlite provides aeration and drainage, yet retains and holds substantial amounts of water that it releases when needed.
• The water-holding ability of Perlite also increases the nutrient holding capacity when water-soluble fertilizers are used.
• Can be used by itself, mixed with topsoil or potting soil, or any other sterile media for drip or passive hydroponic systems.
• Lightweight Perlite does not crush fine stems or root systems, making it ideal for growing delicate plants such as lettuce.
• Chemically inert, does not deteriorate and has an essentially neutral pH.
