Perlite is a volcanic glass that is heated to 871 C. whereupon it pops much like popcorn and expands to 13 times its former size, resulting in an incredibly lightweight material. It’s an amazing soil amendment.
Perlite helps prevent soil from being compacted. By doing this, perlite functions as an aid to maintain adequate air or oxygen in the soil, which in turn improves plant respiration. The ability of perlite to improve aeration while it aids in providing water makes it an excellent product for many hydroponic applications.
Perlite is a naturally occurring inorganic, chemically inert, and sterile product, so it does not represent a threat by adding unwanted biologics or pests into your system.
Sold bag contains 3L of perlite.
