As a soil amendment, Perlite (heat-expanded siliceous volcanic rock) is used to improve aeration and drainage. Its moisture and nutrient retention capabilities and lightweight characteristics make it an excellent sterile medium for starting seeds and rooting cuttings. Perlite does not degrade over time, which makes it a long-term solution to many gardening problems.

It can be used in soil applications or in hydroponics.
