Perlite is a soil-free growing medium that has helped to add
aeration to soil mixes for years. It\'s created by
air-puffing
volcanic glass to create an extremely light and porous material. It
has one of the best oxygen retention levels of all
growing
media because of how porous it is.
Its weight can be a downside in certain hydroponic systems where
water interacts directly with the growing media, causing it
to
shift around and wash away. Because of this, perlite is rarely ever
used alone typically it is mixed with coco coir, soil,
or
vermiculite
