Abstract: A method and apparatus for growing plants (P) hydroponically includes a plant substrate material (52, 54, 56) comprising activated carbon and/or carbonized fibers with or without additional, non-carbonated, non-activated cellulosic fibers. The activated carbon and/or carbonized fibers with or without the additional, non-carbonated, non-activated cellulosic fibers are usable in bulk or manufactured into slabs (56) or other configurations by any of a variety of non-woven, woven, molding, or other techniques. The activated carbon and/or carbonized fibers are made from cellulosic or synthetic carbon fibers, for example, bamboo fibers.

Abstract: A homogenous, free-flowing, resin containing 80 to 90 weight percent of polypropylene and 10 to 20 weight percent of liquid organic peroxide, where the weight percents are based on the total weight of the polypropylene and the liquid organic peroxide, is provided. Furthermore, a process is provided for producing this polypropylene by mixing 80 to 90 weight percent of polypropylene, in the form of 100-500 micron particles, with 10 to 20 weight percent of liquid organic peroxide, where the weight percents are based on the total weight of the polypropylene and the liquid organic peroxide.
