Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
312 words
An enclosed hydroponic apparatus for the use in growing plants comprising a free standing reinforced base including a substantially rectangular lower tray comprising a bottom wall having side walls extending upwardly therefrom and a substantially rectangular upper tray including a bottom wall having side walls extending upwardly therefrom comprising a plant compartment operatively coupled to the upper portion of said side walls of said substantially rectangular lower tray to cooperatively form a nutrient compartment therebetween, a nutrient feed supply disposed in said substantially rectangular lower tray, a plant enclosure including a frame to support a plurality of partitions attached to the upper portion of said side walls of said lower tray said frame comprises a pair of upper and lower channels disposed on opposite sides of said enclosed hydroponic apparatus held in fixed spaced relationship relative to each other by upright members extending therebetween, end partitions fixedly attached to said upper and lower channels and side panels comprising of first and second panel members disposed on opposite sides of said frame slidably attached to said upper and lower channels the distance between said pair of upper channels being substantially greater than the distance between said pair of lower channels such that said first and second panel members diverge outwardly from said lower channels to said corresponding upper channels, a heater system including a heater disposed within said nutrient compartment in combination with an inlet and outlet heat ports formed in opposite ends of said upper tray and an inlet and outlet heat channel extending upwardly from said inlet and outlet ports respectively into said plant enclosure to provide circulation of heated air by convection through said plant enclosure and at least one convex light absorbing element comprising a frosted bubble-like member mounted on the upper portion of said frame to intercept and direct light to the plants disposed within said plant enclosure.
