WE Hydroponics Perlite Agriculture Growing Media Potting Mixture  (1 kg, Granules)

Perlite is a white, sterile propagating medium used by growers to keep soil loose, allowing air and water to reach roots. It is ideal for seeds germination, for potting plants, to root cuttings, to hold cut flower and to help establish new lawns. In horticulture, perlite can be used as a soil amendment or alone as a medium for hydroponics or for starting cuttings. All of these are natural minerals, and are often part of other soil blends. It has a pH of 6.6 to 7.5.
