Shalimar Perlite Water Saver
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian.
Perlite is used in soil mixes (including soilless mediums) to improve aeration and modify the soil substructure, keeping it loose, well-draining and defying compaction. A premium mix of one part loam, one part peat moss, and one part perlite is optimum for container growing, enabling the pot to hold just enough water and oxygen.
