Description:
Perlite
A lightweight volcanic material that improves drainage and aeration while helping keep growing mixes loose and open around the roots.
Perlite is one of the most useful all-round amendments for indoor plants and can be mixed into almost any growing medium where extra airflow or faster drainage is needed.
 
Available in 5L sizes. 
 
Rays Says:
"Perlite is one of those products that does a bit of everything. Add it to a soil or aroid mix for better airflow and drainage, use it for propagation, or mix it into heavier media to help stop it compacting.
It’s light, simple and incredibly useful to have on hand."
