ABSTRACT:
Automated hydroponic plant growing apparatus, for providing an equal supply of nutrient solution, at a controlled rate, to plants in each of a plurality of individual growth chambers, with provision of flow irrigation of each plant in each chamber. The apparatus provides for fully powered, pressurized flow of nutrient solution through separate lines to each growth chamber, and provides for automatic maintenance of equal levels of nutrient solution in the various chambers of the system, having return flow lines for return of any excess accumulation of nutrient solution from any one growth chamber to the central distribution chamber. Through provision of pressurized flow of nutrient solution to the growth chambers, the system avoids any need to rely even in part on gravity flow of nutrient solution, and so may be used with all components located on a single level, e.g. all resting on a common floor. A Timer controls the pump which pressurizes the nutrient solution flow to the growth chambers, so that nutrient solution will be provided to all of the plants at a desired rate. Return flow lines surround and enclose the lines for flow of nutrient solution to the growth chambers, so as to halve the line clutter associated with these lines.
