Expanded perlite

Expanded Perlite is a natural volcanic rock that is extremely light, chemically inert, pH neutral, stable and unalterable over time, and highly porous. These physical characteristics make perlite a mineral matrix that, when added to potting soils, guarantees excellent water absorption, which it then progressively releases to the soil along with fertilisers, playing the role of soil drainer. In this way, the soil remains oxygenated and aerated, filtering excess water and protecting the root systems from sudden changes in temperature, allowing them to develop properly.
