Hydroponic plant cultivating apparatus

A hydroponic plant cultivation apparatus comprising:

• a reservoir for holding fluid, the reservoir having a first portion and a second portion arching upward from the first portion;
• an upper opening defined in the second portion, the upper opening including a first lip with at least one angular stop element formed on a surface thereof, and a second lip vertically offset from the first lip;
• a conduit in fluid communication with the reservoir extending above the upper opening;
• a plurality of planting modules stacked atop one another in an end to end configuration above the upper opening in the second portion of the reservoir, each module including a sidewall, an interior space, at least one planting port defined in the sidewall for receiving a plant at least partially into the interior space, a top end, a bottom end configured to releasably engage the top end, and a wall including a plurality of drain holes and a module conduit aperture through which at least a portion of the conduit extends, wherein the bottom end of each module includes a first nesting portion configured to nest inside the first lip, a second nesting portion configured to nest inside the second lip, and at least one protrusion formed on a surface of the first nesting portion, the at least one protrusion configured to engage the at least one angular stop element to limit relative rotation between the bottom end of the module and the upper opening of the reservoir;
• and
• a fluid distributor positioned atop the plurality of planting modules, the fluid distributor in fluid communication with the conduit;
• wherein fluid is selectively circulated from the reservoir through the conduit to the fluid distributor, where the fluid is redirected down through the interior space of each planting module and back to the reservoir.

A hydroponic plant cultivation apparatus comprising:

• a reservoir for holding fluid, the reservoir including a lower portion and an upper portion, the upper portion extending upward from the lower portion at an acute angle with respect to a vertical axis of the reservoir, the upper portion having an upper opening vertically offset from the lower portion, the upper opening including a first lip, a second lip spaced from the first lip, and a plurality of angular stop elements formed on a surface of the first lip;
• a planting column defining an interior space, the planting column having a bottom end which is releasably engageable with the upper opening in the reservoir, the bottom end including a first nesting portion configured to nest inside the first lip, a second nesting portion configured to nest inside the second lip, and a plurality of protrusions formed on a surface of the first annular nesting portion, the protrusions configured to abut against the angular stop elements to limit relative rotation between the bottom end of the planting column and the upper opening of the reservoir when the planting column is releasably engaged with the reservoir;
• at least one planting port defined in the planting column for receiving plants at least partially into the interior space of the planting column;
• a conduit receivable in the planting column, the conduit in fluid communication with the reservoir when received in the planting column and the planting column is engaged with the upper opening in the upper portion of the reservoir;
• a fluid distributor releasably engageable with a top of the conduit, the fluid distributor in fluid communication with the conduit when the fluid distributor is engaged with the top of the conduit;
• a pump receivable in the reservoir;
• and
• a fluid coupler configured to fluidly couple the pump to the conduit when the planting column is engaged with the upper opening in the upper portion of the reservoir and the conduit is received in the planting column;
• wherein fluid is selectively circulatable from the reservoir through the conduit to the fluid distributor, where the fluid is redirected down the interior space of the planting column and back to the reservoir when the planting column is engaged with the reservoir, the pump is received in the reservoir, the conduit is fluidly coupled to the pump, and the fluid distributor is engaged with the conduit.
