Perterra - Expanded Perlite
Lightweight volcanic mineral from Milos, Greece for superior soil conditioning.
Perterra is produced from mineral perlite, mined on the island of Milos in Greece. Perlite is an inorganic aluminosilicate mineral of volcanic origin with 3-4% crystalline water in its structure. Without any chemical admixture, perlite is heated to approximately 1,000°C, resulting in its expansion. The material is very lightweight and can hold up to 3-4 times its weight in water with total porosity of about 95%.
