Specifications
1.price is competitive. 2.time of the delivery is shot. 3.our perlite is tested by SGS test.?Liquid retention:
Perlite’s porous texture retains moisture and fertilizers. With appropriate granule size, perlite provides optimal irrigation as well as perfect drainage for all your horticultural projects.
Air circulation:
Because of their irregular shape, perlite particles provide aeration in growing mixes and substrates, and in many industrial applications
