Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A hydroponic apparatus comprising a support means having a plurality of mutually supporting diagonally disposed plant trays supported thereon and a nutrient feed supply disposed within said plurality of plant trays, each said plant tray includes a plurality of plant supports having nutrient feed apertures formed therein such that each plant is fed directly from said nutrient feed supply, said nutrient feed supply comprises a pump disposed within said plurality of plant trays and a nutrient feed supply manifold having a plurality of nutrient supply apertures formed thereof in combination with a plurality of nutrient feed supply panels corresponding to each of said plant trays wherein said corresponding nutrient feed supply panels and said plant trays are arranged relative to each other to feed nutrient to the base of said plant supports.
Claim 2
Dependent Claim
132 words
