Horticultural Grade Perlite

Boost aeration and drainage in your growing mixes with our Horticultural Grade Perlite. Made by air-puffing volcanic glass into an ultra-light, porous material, it offers some of the best oxygen retention of any growing medium, helping roots breathe and thrive. Mix it through potting blends to prevent compaction, or use it on its own as a substrate for passive and recirculating hydroponics, rooting cuttings and propagation. A versatile, long-trusted staple for healthier roots and stronger plants across all your gardening projects.
