  • Gravity feed hydroponic system
    Patent number: 4756120
    Abstract: A system for hydroponically growing plants in a vertical array includes a vertical cylindrical column made up of stacked column sections adapted to contain an inert support material, the column sections including top and bottom openings and a plurality of side apertures. A nutrient reservoir is provided for positioning above the column and adapted to contain a nutrient solution. The introduction of nutrient solution into the column is controlled by an adjustable valve supported above the top opening of the column for gravity feed of nutrient solution into the column. The valve is positioned to permit visual inspection of the rate of introduction of nutrient solution through the valve and into the column. A conduit connects the valve to the nutrient reservoir.
