ABSTRACT:
A plant watering system that is controlled and operated in cycles by the heating effects of the sun, the system including a sealed water supply tank; a metering reservoir having a water supply conduit connected to the supply tank for delivering water from the supply tank to the metering reservoir, a float operated ball valve, and a triggering mechanism for releasing water from the metering reservoir; and, a distribution tank having an air relief conduit connected to the supply tank, a float operated pressure relief valve for releasing vapor pressure in the water supply tank through the air relief conduit; and, a distribution network for distributing the water to one or more plants, the system being operated by exposing the water supply tank to the sun causing delivery of water to the metering reservoir by vapor pressure in the tank, the metering tank releasing the water to the distribution tank for distribution when a predetermined quantity of water in the metering reservoir is obtained, the released water in the distribution tank operating the pressure relief valve, relieving the vapor pressure in the sealed tank and, after dispensing the water, to the plants initiating renewal of the cycle.
