Perlite is a naturally occuring, volcanic rock. When furnaced at high temperatures, Perlite “pops” and expands 7 to 15 times its original volume. The resulting lightweight particles are made up of microscopic spheres with a porous, broken surface that promotes plant growth. This allows aeration and drainage of the root system and provides holding capacity for water and nutrients.
