  • Light-weight modular adjustable vertical hydroponic growing system and method
    Patent number: 9591814
    Abstract: A light-weight, modular, adjustable vertical hydroponic growing system and method of Native American design for cultivation plants and beneficial soil organisms (BSO's) in symbiotic combination. Forest-like arrays of fully rotatable and demountable grow tubes are suspended within climate-moderating greenhouses, optionally from conveyor tracks. The tubes are filled with light-weight, porous 100% in-organic grow media predominately comprised of expanded volcanic or recycled glass granules. The grow tube arrays are provided with an insulated, overhead-mounted fertigation distribution system delivering metered intermittent flows from insulated mixing and holding tanks. The flows are recycled via an insulated return piping system to maintain cool fertigation temperatures near those of natural ground water.
