Mother Earth® Perlite is 100% naturally occurring siliceous rock that when heated to 1600° F expands up to 20 times its original volume.
This is the coarsest perlite you will find in the UK, with average size of 1cm. We have included a photo showing this perlite alongside the standard 'coarse' perlite sold in the UK.
Each bag contains 2 litres of perlite.
