ABSTRACT:
The present invention discloses a synthetic cultivation medium comprised of fibrous glomerates and a method for manufacturing the same. Absent a soil component, the synthetic cultivation medium is manufactured from scrap, man-made textiles, chiefly those made from polyacrylonitrile or polyester fibers. In manufacturing the cultivation medium, scrap textiles are shredded into short fibers and chemically refined and bleached. Prior or subsequent to the chemical refinement and bleaching, the short fibers are agitated into glomerates of intertwined fibers.
