1.Horticultural Perlite:
Horticultural Perlite is a naturally occurring volcanic rock. When heated at high temperatures, the perlite sand "pops up" and expands 7 to 15 times its original volume. The resulting lightweight particles are composed of microscopic spheres with a porous fracture surface that promotes plant growth. This allows ventilation and drainage of the root system and provides water and nutrient retention.
