Patent ID: 7516574

Claim:
A vertical garden comprising: a reservoir containing a nutrient rich liquid; a stack of modular members nested together above said reservoir; a vertically extending pipe passing through central openings in said modular members, said pipe communicating with an enclosed, extended manifold adjacent a bottom of said reservoir; an air pump outside of said reservoir having an outlet hose terminating in an air inlet port adjacent one end of said manifold so that compressed air flowing from said air pump enters said manifold and flows up through said vertically extending pipe; said manifold having a liquid inlet port at an opposite end of said manifold allowing inflow of said liquid, the compressed air rising in said vertically extending pipe entraining some of said liquid, an entrance to said vertically extending pipe being between said air and water inlet ports; means comprising a diffuser plate for covering a central opening at a top of the uppermost modular member having an opening to accommodate an upper end of said vertically extending pipe extending above said diffuser plate and a plurality of openings in said diffuser plate to permit liquid exiting from the top end of said vertically extending pipe to drip down through said modular members, the upper end of said vertically extending pipe having an unrestricted outlet; and each modular member having radiating planter ports for growing plants, said planter ports containing plant media, whereby said nutrient rich liquid is delivered to said stack of modular members without any moving parts in said reservoir or stack of modular members.
