PERLITE - Coarse

Perlite is an amorphous volcanic glass, a hydration of obsidian. Perlite has the unique characteristic of expanding to many times its original volume when heated, a process called exfoliation.

They offer a proprietary processing technique to enhance the efficiency of their custom blending operations where perlite is a component of the finished product.

This lightweight Perlite provides superb aeration and moisture retention when mixed in with other soil materials. Perlite supports root growth and retains moisture, air, and nutrients which it releases as plants grow. Also suitable for hydroponic greenhouses. Can be made very low-density as required. Easy handling, loading & unloading.
