ABSTRACT:
A multiple function hydroponics system consisting of three major components; a plant pot container, a reservoir container and a pumping chamber. The plant pot container has a drainage tube down into the reservoir, this drainage tube height is adjusted to determine the upper level that the liquid can reach within the plant pot container. For a ebb and flow type operation of the assembly there is a siphon tubes from the bottom of the plant pot container back into the pumping chamber to drain the plant pot container each cycle. For top down watering or a drip system a watering tube assembly is installed so that each plant has an fluid outlet opening. The liquid pumping chamber, which contains a cycling container, is connected to the bottom of the reservoir with tubing and a one way valve allowing liquid to enter. When in the top down watering mode, the height of the drainage tube within the plant pot container is lowered so as to allow complete drainage back into the reservoir. The incoming pressurized air coming into the pumping chamber enters at the lowest level so as to aerate the water. In operation with the cycling container resting near the bottom of the liquid pumping chamber the gas within the system is expanded in the pumping chamber, the resultant pressure build-up in turn force's liquid out of the cycling container tube and the siphoning tube. When the chamber's liquid reaches a predetermined level, the pressurized gas is released to the atmosphere through the cycling container tube, liquid from the plant pot container refills the pumping chamber through the siphon tube, and the reservoir as the pumping chamber is now open to the atmosphere. When the pumping chambers refill to a predetermined level, the cycling container sinks and the cycle repeats.
