PERLITE – MEDIUM GRADE – 100 LITRE BAG (s242)
Horticultural Perlite is a unique volcanic mineral which expands from four to twenty times its original volume. When expanded each granular, snow-white particle of Perlite is sterile with a neutral pH and contains many tiny closed cells or bubbles. In addition, because of the physical shape of each particle, air passages are formed which provide optimum aeration and drainage.
