发明名称 Hydroponic growing apparatus
摘要 A hydroponic plant growing apparatus is disclosed wherein a nutrient enriched liquid is flowed within a series of ducts adapted to mount a plurality of planting cups, each of which support a sterile media and a plant seedling. The planting cup includes an apertured bottom surface which permits capillary action of the nutrient liquid into the support media as well as allows the root system of each plant to extend into the duct yet isolates the sterile media from direct flow contact with the nutrient liquid. The individual plant cups eliminate contamination of the nutrient liquid, facilitate easy removal and replacement of individual plants on the apparatus, and form an effective seal with the ducts yielding a substantially hermetically sealed apparatus which is not susceptible to rain contamination, evaporation, or algae growth.
