China Expanded Perlite Particles for Agricultural Garden

expanded perlite pearlite

perliteis 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

each particle of perlite is comprised of tiny closed air cells or bubbles. the surface of each particle is covered with tiny cavities which provide an extremely large surface area.

these surface cavities trap moisture and make it available to plant roots. in addition, because of the physical shape of each particle of perlite, air passages are formed in the growing media thereby providing excellent aeration.
