A gardening appliance includes a grow tower rotatably mounted within a liner and defining a root chamber. A mixing tank defines a water inlet, a nutrient inlet, and a mixture outlet. An overflow protection system is operably coupled to the mixing tank and includes a wastewater reservoir, an overflow port fluidly coupled to the mixing tank, an overflow conduit providing fluid communication between the overflow port and the wastewater reservoir, and a one-way overflow valve fluidly coupled to the overflow conduit to prevent liquid flow back into the mixing tank.

Various embodiments include a container for hydroponically growing plants. The container has a bottom surface and an open top surface and a fluid reservoir having at least a portion of the volume between the bottom surface and the top surface. A pump is positioned at a bottom portion of the fluid reservoir. A length of tubing connects the pump to a valve that is further connected to additional tubing. A plurality of jets are connected to the additional tubing to spray fluid internal to the fluid reservoir. Further, there is a support structure, configured to fit into the open top surface, that has support components for interconnecting a plurality of openings and supporting the plurality of jets. Finally, a cover plate is configured to fit over the support structure in the open top surface.

Embodiments described herein relate to plant support systems and methods of operating the same. In some embodiments, a plant support system includes a housing that physically supports a plurality of living plants. The housing includes a plurality of panels arranged in a vertical array of n rows and m columns, n and m being positive integers. Each panel from the plurality of panels contains a living plant from the plurality of living plants. The plant support system further includes a plurality of pumps. Each pump from the plurality of pumps delivers water to one of the rows in the housing. In some embodiments, the plurality of pumps includes a first pump programmed to deliver a first volume of water to a first row of the plurality of panels at a first pressure head corresponding to a height of the first row of the plurality of panels.

The invention relates to a system for growing plants out of seeds on a water surface. The system has a buoyant plate with a number of passages extending between the top surface and the parallel bottom surface. The plate floats on a water surface. A container is arranged in each passage and a growing seed is arranged in each container.
