Vertical growing uses a plurality of shelves to support plants. The system provides nitrogen and light to help grow the plants placed on the shelves. The system also circulates air that is filtered and mixed with the nitrogen before being distributed to the plants. The filters can remove odors from the circulating air.

A plant cultivation light source includes a plurality of light sources configured to be turned on or turned off depending on a selected plant and a growth stage of the selected plant, and a controller. The controller is operable to turn on the light sources during a light period such that the light sources are operable to emit a light having a spectrum with a plurality of peaks to the selected plant. The light period including a first period and a second period and the first period preceding or following the second period. The controller is operable to adjust the spectrum of the light to alternate the first period and the second period during the light period.

A plant illumination device may include an elongate body comprising: a light propagating section, a light quenching section coupled to a first end of the light propagating section, and, optionally, a light conducting apex coupled to a second end of the light propagating section. In some embodiments, the light conducting apex acquires light which propagates to the light propagating section. The light propagating section may be positioned in proximity to a non-root portion of a plant and the light quenching section in proximity to a root system of the plant. In some embodiments, the light is prevented from reaching the root system of the plant by the light quenching section. In some embodiments, the light includes sunlight, green light, or red light.

An apparatus for growing plants in a grow room includes an enclosure having a window. The enclosure contains a grow lamp that is arranged to direct light downward through the widow toward the plants. A blower is coupled with the enclosure to drive a flow of air through the enclosure. A gantry apparatus supports the enclosure in the grow room for movement above the plants.

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.

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.
