A storage racking system for plant products can be capable of automated rotation and curing of dried cannabis and hemp flowers in sealed containers, which can maintain relative humidity along with a UV light and oxygen deficient environment to reduce degradation. The storage containers can be positioned horizontally to maintain a connection to the inert gas connection and allow for daily rotation in either direction. Each storage container can have a lid and a humidity pack. The lid can have a pressure relief valve that can exchange the gaseous atmosphere from the storage container with an inert gas through a check valve connection. The humidity pack can maintain the relative humidity in the storage container at about 58% to 62% during the curing and storage stages.

In a device a crop is cultivated in an at least substantially daylight-free environment, wherein the crop is exposed in an at least substantially fully conditioned cultivation space (10) to actinic artificial light from an array of artificial light sources (30) present in the cultivation space. During a cultivation cycle a power output of the artificial light sources (30) is adapted to an energy absorption of a part of the crop (50) illuminated thereby such that the crop close to each of the array of artificial light sources is subject to an at least substantially constant and at least substantially mutually equal vapour deficit.

A height-adjustable botanical lighting system and a method of operating the same. The height-adjustable botanical lighting system comprises a height adjustment assembly, one or more light assemblies, and one or more sensors. The light assemblies depend from the height adjustment assembly. The sensors are adjustably coupled to the light assemblies. The sensors cause the height adjustment assembly to raise the light assemblies in response to one or more generally upward advancing plants interfering with a sensor field of the sensors.

Systems and methods disclosed herein include a method of illuminating plants in an indoor farming environment, including illuminating one or more plants using one or more lighting fixtures at a light intensity of approximately 1500 μmol/m.sup.2/s during a daytime period, wherein each lighting fixtures comprises one or more LEDs, determining whether a daytime temperature of the indoor farming environment is within a daytime temperature range, adjusting the daytime temperature to be within the daytime temperature range in response to determining that the daytime temperature of the indoor farming environment is outside of the daytime temperature range, determining whether a daytime humidity of the indoor farming environment is within a daytime humidity range, and adjusting the daytime humidity to be within the daytime humidity range in response to determining that the daytime humidity of the indoor farming environment is outside of the daytime humidity range.

The present invention provides a method for promoting plant growth, a plant lamp and application thereof. The method at least includes providing an artificial light source for a growing plant. The light source includes a red light with a peak wavelength of 680-695 nm and a light wave half-width lower than 35 nm; or the light source includes a blue light with a peak wavelength of 410-440 nm and a light wave half-width lower than 35 nm. The plant lamp provides the light source for promoting plant growth. By using the light source in the present invention to irradiate the plant, plant growth is significantly promoted.

The system may include at least one light, at least one liquid conduit, and at least one gas conduit. The system may include at least one robot disposed on a top side of the frame and movably supported by the frame. The at least one robot may include at least one tool configured to manipulate the plurality of vertical plant growth structures. The system may include a control system including at least one processor configured to automatically control illumination by the at least one light, liquid flow through the at least one liquid conduit, gas flow through the at least one gas conduit, and operation of the at least one robot.

A magnetic device for growing plants has a body, a set of magnetic elements and an actuation mechanism. The body has a space enclosing a base of the plants and allowing the plants to grow out of the space along a vertical axis. The magnetic elements are coupled to the body and surround the space so as to generate an axial magnetic field in the space. The actuation mechanism is coupled to the body so as to rotate the magnetic elements around the space and about the vertical axis. The base of the plants exposed to the rotating magnetic field to enhance growth of the plants.
