Horticulture Perlite:

Among the unique properties of Horticultural Perlite is its ability to work for many years in the soil. It does this because it is inorganic and does not deteriorate. 

 

 

 

 

 

 

 

In addition, perlite is chemically inert and has an essentially neutral pH. Because it is sterile, perlite is free of disease, weed seeds and insects. its lightweight density makes Perlite easy to handle, it is clean and odorless as well. 

 

100% Natural Product:

Perlite is a naturally occurring, 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.
