Patent ID: 8893431

Claim:
A gardening apparatus comprising: A) an outer shell encapsulating an inner structure and liquid delivery system, B) at least one inner structure within the outer shell with at least one generally planar medium capable of supporting a plant or seeds in growth medium when aligned vertically and capable of retaining liquid, and C) a liquid delivery system within the outer shell wherein the liquid delivery system comprises: i) a first refillable and sealable reservoir positioned above the inner structure and capable of dispensing liquid into the inner structure though at least one opening, ii) a second refillable reservoir positioned below the inner structure capable of receiving water from the inner structure, and iii) a tube connecting said first and second reservoirs wherein said tube is open on each end and wherein the open end of the tube in the second reservoir is positioned in a bottom portion of the second reservoir, wherein said tube enables a liquid dispensing negative feedback loop between said first and second reservoirs by creating a partial vacuum in the first reservoir when the water level in the second reservoir submerges the end of the tube in the second reservoir and wherein said vacuum inhibits the dispensing of liquid by said first reservoir and wherein when the liquid level of the second reservoir recedes to a level where the tube is no longer covered by liquid the partial vacuum is destroyed and liquid from the first reservoir again begins to flow through the at least one opening.
