Perlite may be used as a growing medium which finds application in potting mixes, turf and hydroponic blends.
• Perlite provides structure to a growing medium which improves the aeration of root systems and ensures adequate drainage.
• Coarser/dust free grades of perlite improves root growth and allows for the formation of air pockets.
• Perlite does not decompose or break down in the growing medium like its organic counterparts, thereby ensuring that aeration to the plants roots is maintained.
• Perlite is physically stable and will retain its excellent air/water balance for many years if handled carefully.
Perlite is a non-toxic, naturally occurring siliceous volcanic rock. Perlite is formed by the rapid cooling of viscous magma or lava. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four (4) to approximately twenty (20) times its original volume! Perlite is an inert and odourless mineral which is 100 % safe to use in Horticultural applications.
