Abstract

Abstract An automatic self-watering system for plants growing in a container includes a water receptacle above the level of growing medium in the container. The water container may be of any appropriate shape, and may be attached to or located adjacent an upper edge of the container. Alternatively, the water container may have legs resting on or inserted in the growing medium, or may be hooked onto the edge of the container. The water receptacle may be formed separately from or integrally with the container. A conduit for transporting water is connected to an outlet in the side or base of the water receptacle and the conduit is engaged with a dryness sensor inserted in the growing medium in the container. The dryness sensor automatically closes the conduit when the growing medium is adequately irrigated, and opens the conduit to allow water to drip onto the growing medium when water is needed. The outlet from the conduit is positioned so that water drips, by gravity, onto the root area around a plant growing in the container. The container may also be used for holding a separate pot for a plant which fits in the container.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 83 words
An automatic self-watering system for plants growing in growing medium in a container comprising: receptacle means for holding water being supported in a position above the level of growing medium in a container for growing plants, sensor means for creating a variable vacuum for sensing dryness in the growing medium; and conduit means for conducting water from said receptacle means to the growing medium in response to sensed dryness of the growing medium sensed by creation of a vacuum in said sensor means.
Claim 2
Dependent Claim 83 words
An automatic self-watering system for plants growing in growing medium in a container comprising: receptacle means for holding water being supported in a position above the level of growing medium in a container for growing plants, sensor means for creating a variable vacuum for sensing dryness in the growing medium; and conduit means for conducting water from said receptacle means to the growing medium in response to sensed dryness of the growing medium sensed by creation of a vacuum in said sensor means.
Claim 3
Dependent Claim 22 words
An automatic self-watering system according to claim 1 wherein said receptacle means comprises an outlet for water in a lower portion thereof.
Claim 4
Dependent Claim 20 words
