Perlite is a form of volcanic glass mined all over the world and used as a soil additive.
Use of soil amendments like perlite increases aeration for the roots allowing it to absorb more oxygen
Perlite is porous and would allow more drainage for plants that do not require moist media while keeping much needed nutrients. It is ideal for cactus and succulent soil or any other plants that thrive in well-draining soil.
