A modular LED grow light system is provided that includes one or more LED grow light modules. Each of the LED grow light modules includes one or more connecting ports and an LED. The one or more connecting ports are configured to connect to another LED grow light module. A power source is connected to one of the connecting ports of the one or more LED grow light modules. The LEDs of the one or more LED grow light modules provide light to a portion of a plant.

Disclosed herein are a light source module for plant cultivation and a light device including the same. The light source module for plant cultivation may include at least one main light source emitting white light. The white light from the main light source is provided to a plant during cultivation to improve the growth and phytochemical content of the plant. In addition, the white light may have peak wavelengths of 430 nm or less, 440 nm to 460 nm, 510 nm to 530 nm, and 600 nm to 630 nm.

A lighting system is provided with an illumination device with a semiconductor light emission solution and device suited for plant cultivation in a greenhouse environment are described. A lighting device with binary alloy quantum dots made by colloidal methods produces a size distribution of quantum dots that produces an emission spectrum similar to the photosynthetically active radiation (PAR) spectrum. The methods and arrangements allow more precise spectral tuning of the emission spectrum for lights used in plant cultivation. Therefore unexpected improvements in the photomorphogenetic control of plant growth, and further improvements in plant production are realized.

Information of plant based on color of a surface of plant is acquired from image data obtained by imaging plant, allowing to acquire information of plant at low cost, compared to chlorophyll meter or spectroscopic analyzer. In crop production like rice plant, fertilization management including fertilizer application management like fertilizer amount determination, or other agricultural works, is supported through a smart phone or the like based on data to be observed, like converted leaf color value is calculated from image data obtained by crop imaging. Camera is connected to smart phone. Converted leaf color value can be obtained from image data obtained by imaging leaf of rice plant by camera. Converted leaf color value is transmitted to management server, for example, amount information of applied fertilizer is required in case where converted leaf color value is less than standard, can be obtained as management information for fertilizer application management.

A light wall for cultivating at least one plant indoors may be provided. The light wall may include a first side, a second side, a top side, a bottom side, a front side, and a back side. The light wall may further include a first lighting structure unit disposed within sides of the light wall, and may include a first set of mechanical devices configured to enable movement of the light wall. The first lighting structure may be configured to provide light to the at least one plant through at least the first side. The first set of mechanical devices may be configured to enable movement at least along an axis substantially perpendicular to the first side.

Methods of installing and using a horticulture lighting controller having a substantially rectangular shaped housing with an in-operation removable front cover panel, the methods preferably comprising mounting the fully assembled lighting controller to a mounting surface without first having to remove any component of the controller, remove a front or outer cover of the controller, perform any wiring connections on a backside or backplane of the controller chassis, or pre-wire any connections whatsoever, and then removing the front cover panel to connect the controller to a power supply circuit.

Embodiments described herein provide systems for inducing a desired response in an organism by controlling the duty cycle, wavelength band and frequency of photon bursts to an organism, through the photon modulation of one or more photon pulse trains in conjunction with one or more different photon pulse trains to the organism and duty cycle, where the photon modulation and duty cycle is based upon the specific needs of the organism. Devices for inducing a desired response in an organism such as growth, destruction or repair through the photon modulation of one or more photon pulse trains in conjunction with one or more different photon pulse trains to the organism are also provided. Further provided are methods for the optimization of organism growth, destruction or repair through the use of high frequency modulation of photons of individual color spectrums.

Techniques for horticulture light are provided. A horticulture light can monitor at least one characteristic of a defined region in which at least one plant is planted in a horticulture environment in which horticulture light bulb is installed, determine at least one action for the horticulture light bulb to perform based on a state of the at least one characteristic and at least one objective of the installation of the horticulture light bulb in the horticulture environment, and execute the at least one action.

The present invention relates to a method for determining a growth status of a plant comprising chlorophyll, the method comprising the steps of: illuminating the plant (102) with input light including a light intensity modulation component (205, 206, 207, 208); detecting light emitted from the plant; determining (S702) an offset light intensity (204) surrounding the plant, the offset light intensity being a static component of the input light; determining (S718) a phase and a gain between the input light and the detected light, determining (S720) a growth status of the plant based on a predetermined relationship between input light and detected light, and on the phase and the gain. The invention also relates to a corresponding system and to a computer program product.
