Perlite is an amorphous volcanic glass that has high water content, is used in soil mixes, and is also a soilless medium. This medium improves aeration and changes the soil substructure, keeping it loose, well-draining, and defying compaction. Perlite is also great for rooting cuttings and encourages the development of much stronger root formation.
Each pack contains 150 grams of perlite. Size: 3-5mm
