  • Patent number: 5394647
    Abstract: A new virtually self-contained hydroponic plant growing system has a horizontal tubular chamber capped at each end, the chamber having a series of holes along its top for supporting a plurality of specially constructed flower pots or cups having holes in their bottoms to enable root growth outside of the pot or cup to access the plant nutrients. The pots or cups can contain similar and/or different vegetables and other plants. A horizontal divider containing a series of small drip holes extends from end to end within the center of the tubular chamber. A water pump, which can be solar powered, circulates water and other nutrients from a reservoir system through a spray means inside the tubular chamber based on a timer set to deliver the water and other nutrients at optimal times to maximize growth.
