A plant cultivation device includes a light source unit having a first light source emitting stimulation light in a UV region toward a plant and a second light source emitting background light toward the plant, the background light having a different peak wavelength than the stimulation light. The second light source emits the background light during a light period and stops emission of the background light during a dark period. In addition, the first light source emits the stimulation light for a certain period of time during the light period. Further, a cumulative amount of the stimulation light emitted from the first light source is 0.036 J or more per day.

A vertical farming structure having vertical grow towers and associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, while being exposed to controlled lighting, airflow, humidity and nutritional support. The present disclosure describes a reciprocating cam mechanism that provides a cost-efficient mechanism for conveying vertical grow towers in the controlled environment. The reciprocating cam mechanism can be arranged to increase the spacing of the grow towers as they are conveyed through the controlled environment to index the crops growing on the towers. The present disclosure also describes an irrigation system that provides aqueous nutrient solution to the grow towers.

A sterile packaged plant delivery system includes a container having an opening, an amount of growth medium, a plant, and cover. The amount of growth medium is disposed within an interior of the container and part of the plant is disposed within the growth medium. The cover seals the interior of the container thereby maintaining the plant within a sterile growth environment. In one example, the cover is a thin film seal. A user obtains the system, punctures the film seal, removes the plant from the interior of the container, and plants the plant in a growth environment outside of the container. The system provides a low-cost technique for delivering live plants to end consumers without fungus or bacteria as in typical soil growth and without having to apply costly antimicrobial agent. This eliminates the need for watering and maintenance of any kind while the plant remains in the container.

An indoor gardening appliance includes a grow module that is seated on a turntable that is rotatably mounted within a grow chamber and is rotated by a drive assembly. A position sensing assembly monitors an angular position using two proximity sensors, such as Hall-effect sensors, mounted below the sump, and the turntable includes a plurality of proximity indicators, such as magnets, positioned at various circumferential positions on the turntable. A controller is configured to initiate rotation of the turntable from a first angular position, determine that the turntable should have reached a second angular position, e.g., based on the operating duration or drive signal of the drive motor, and identify a drive assembly fault upon determining that the turntable has not reached the second angular position.

A product holder assembly for a mobile cultivation of plants along a path in a hall includes a product holder having a bottom and an upstanding circumferential wall extending from the bottom, a first space extending from the bottom of the product holder along the wall to allow a medium or substrate for roots of the plants to receive nutriments and/or support from, a grid system arranged to be placed on the product holder to cover the first space in the product holder and to separate the first space from a second space adjacent to the grid system at a side of the grid system facing away from the first space, wherein the grid system is arranged for holding a plurality of separate plants, the roots of which to reach for the first space and the leaves of which to reach for the second space, wherein the grid system is arranged to operate in conjunction with an air duct system.

The present disclosure relates to apparatus for growing plants. More specifically, apparatus described herein relate to an inverted controlled irrigation grow pot (100). In one embodiment, a plant pot includes a multi-walled tube which defines a plurality of volumes therein to facilitate inverted growth of a plant while accounting for the geotropic nature of root proliferation. Embodiments of the disclosure also provide for controlled irrigation of a plant grown in an inverted orientation. Further embodiments of the disclosure provide for plant propagation systems which include multiple plant pots. In certain embodiments, load cells (802, 1002, 1101, 1102, 1202) are incorporated in to the systems to enable detection and measurement of plant pot weights.

The present invention is a scalable and re-configurable system for indoor growing. The scalable and re-configurable system for indoor growing is comprised of a plurality of growing sleds, in which each growing sled has a plurality of plant stations. Plants are grown in receptacles on each plant station. The plant station is rotated by a drive system. Each plant station provides irrigation. Each plant station has a forced frame connected to the top of a plant support assembly. A forced frame is used to confine each plant to a known foot-print. This is necessary in indoor growing in order to make the production uniform and efficient.
