Product Description
wholesale agriculture perlite price bulk perlite perlite for horticulture
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

Perlite advantage
On the basis of absorbing advanced technology from foreign countries such as Japan, Korea, etc, according to Chinese soil characteristic and cultivation habit, researched and developed super lightweight cultivated substance, which is super lightweight, inorganic, easy to construction, innocuous.
Perlite advantage
It has superior nature in preserving water and chemical fertilizer; sustained release; plant rooting, without pests because we adopt volcanic lava with high porosity. It’s widely used in seedling soil media, cultivation substance, soil amendment substance,city greening, garden roof, etc.
