Horticultural expanded perlite
?Perlite
Sterile perlite, a material composed of super-heated volcanic glass, resembles pure white foam pellets. Perlite granules feature small cavities on their surface that trap and hold moisture, which helps retain moisture in an otherwise quick-drying potting mixture. Lightweight perlite also aerates soil because the lightweight pellets prevent the organic ingredients in the soil mix from compacting. Perlite has an alkaline pH between 6.5 and 7.5, which can cause fluoride burn on foliage plants that prefer more acidic conditions.
