A self-contained aeroponic apparatus comprising a reservoir for containing a nutrient solution and a right-angular plant support standing over the upper edge of the reservoir and defining with it a closed chamber. The panels that form the plant support are releasably secured, along edges thereof that adjoin one another, in essentially watertight and light-tight conditions. Likewise, the lower edges of the support panels are releasably secured to the upper edge of the reservoir in watertight and light-tight conditions. Cups for holding plant structures are formed integrally with the inclined hypotenuse wall of the right-angular support. They are open-ended tapered tubes each of a size to snugly hold a plant structure. A nutrient solution spraying system within the chamber serves to supply the solution to the plant structures in the cups. It comprises spraying heads distributed at different levels along the backwall of the plant support; a pump in the reservoir and piping operatively joining the spraying heads and the pump to allow feeding nutrient solution to the spraying heads.

A self-contained aeroponic apparatus comprising: a reservoir for containing a liquid nutrient solution, said reservoir having a bottom wall and upright circumscribing sidewalls, a major portion of said bottom wall slanting toward a sump; a plant support standing over said reservoir; said support comprising a rectangular planar vertical back wall; a rectangular planar inclined front wall and planar end walls located between said back wall and front wall at the lateral edges thereof; means releasably securing together, in essentially watertight and light-tight conditions, said back, front and end walls of said support; means releasably securing together, in essentially watertight and light-tight conditions, the lower edges of said support and adjoining upper edges of said reservoir; said reservoir and said plant support defining an enclosure; a plurality of hollow, open-ended, frusto-conical cups wholly projecting within said enclosure from said front wall exclusively, said frusto-conical cups having their small bases located in said enclosure and being inclined toward said reservoir whereby to ensure self-drainage of surplus nutrient solution back to said reservoir, said cups being formed integrally with said front wall and each adapted to hold, in use, a plant held by a plant support medium consisting of a frusto-conical plug made of a liquid absorbent cellular material selected from the group consisting of foam rubber and foam plastic, the diameter of the small bases of said frusto-conical plugs exceeding that of the small bases of said frusto-conical cups whereby friction, created by expansion of said cellular material beyond the small base ends of said cups, holds said plugs within said cups; and a nutrient solution spraying system within said enclosure, said system comprising a plurality of spraying heads distributed at different levels along said back wall and operatively facing said plant holding cups, a pump located in the sump of said reservoir, piping means operatively joining said spraying heads and said pump and a nutrient solution filter operatively mounted between said pump and said spraying heads; said system being constructed to supply nutrient solution from said reservoir to said spraying heads; and a heater mounted in the reservoir to hold the nutrient solution at an appropriate temperature.
