Abstract
Abstract A hydroponic grower is described which includes a bottom pan for containing a liquid nutrient solution and an A-frame construction which rests therein and supports plants to be grown hydroponically. The plants are supported within pots which, in turn, pass through apertures in the side walls of the A-frame construction so that the root portion of the plants are within the interior of the enclosure defined by the A-frame construction. The root end of each of the pots is permeable to liquid nutrient solution, and a spraying arrangement is provided within the pan to spray liquid therefrom upwardly to wet the roots of plants within such pots.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
297 words
An essentially self-contained and portable hydroponic grower comprising an enclosure having a base pan for containing a liquid nutrient solution; a pair of walls projecting upward from said base pan to support a plurality of plants thereabove, said walls being inclined relative to the bottom of said pan in an A-frame configuration with the apex thereof above said base pan and having their lower ends circumscribed by said pan, each of said walls being generally planar and including a plurality of apertures extending generally normally therethrough communicating with the interior of said enclosure; a plurality of plant pots, each of which is adapted to contain a porous plant support medium and extend through an associated one of said apertures with its side wall in engagement with the peripheral edge of said aperture for said pot to be held in position thereby, the root end of each of said pots being permeable both to the flow of liquid nutrient solution to the interior thereof and to the passage of the roots of plants supported thereby outward; a liquid spray head positioned within said enclosure between said inclined walls to spray a liquid toward roots of plants projecting from the root ends of pots extending through said apertures; a liquid pump positioned within said base pan and connected to said spray head to deliver thereto under pressure a liquid nutrient solution contained in said pan; and end walls at opposite ends of said enclosure extending between said inclined walls and from the apex of said A-frame configuration to said base pan to define with said inclined walls a hollow enclosure containing said spray head and adapted to contain said root ends of said pots, said end walls being substantially moisture impermeable for maintaining a humid atmosphere within said enclosure.

An essentially self-contained and portable hydroponic grower comprising an enclosure having a base pan for containing a liquid nutrient solution; a pair of walls projecting upward from said base pan to support a plurality of plants thereabove, said walls being inclined relative to the bottom of said pan in an A-frame configuration with the apex thereof above said base pan and having their lower ends circumscribed by said pan, each of said walls being generally planar and including a plurality of apertures extending generally normally therethrough communicating with the interior of said enclosure; a plurality of plant pots, each of which is adapted to contain a porous plant support medium and extend through an associated one of said apertures with its side wall in engagement with the peripheral edge of said aperture for said pot to be held in position thereby, the root end of each of said pots being permeable both to the flow of liquid nutrient solution to the interior thereof and to the passage of the roots of plants supported thereby outward; a liquid spray head positioned within said enclosure between said inclined walls to spray a liquid toward roots of plants projecting from the root ends of pots extending through said apertures; a liquid pump positioned within said base pan and connected to said spray head to deliver thereto under pressure a liquid nutrient solution contained in said pan; and end walls at opposite ends of said enclosure extending between said inclined walls and from the apex of said A-frame configuration to said base pan to define with said inclined walls a hollow enclosure containing said spray head and adapted to contain said root ends of said pots, said end walls being substantially moisture impermeable for maintaining a humid atmosphere within said enclosure.
Claim 3
Dependent Claim
29 words
A hydroponic grower according to claim 1 wherein there is a single one of said liquid spray heads positioned within said enclosure to spray liquid toward said plant roots.
Claim 4
Dependent Claim
34 words
The hydroponic grower of claim 1 wherein each of said pots has a shape adapted to facilitate removal thereof from its associated aperture and, hence, the separation of a plant therein from said grower.
Claim 5
Dependent Claim

A hydroponic grower according to claim 3 wherein each of said pots is tapered inwardly toward its lower end to provide a shape facilitating removal thereof from its associated aperture.
Claim 6
Dependent Claim
42 words
The hydroponic grower of claim 1 wherein said pair of inclined walls is separable from said base, pan, and said A-frame configuration is separable into a plurality of parts to enable said grower to be disassembled to facilitate moving and storage thereof.
