In a method and device for cultivating a crop, cultivation takes place in an at least a substantially daylight-free, climate-conditioned cultivation space. The cultivation space extends between a first side and an opposite second side, wherein the crop is exposed to photosynthetically active radiation from an array of spatially separated artificial light sources. An airflow is guided over the crop from the first side to the second side. The artificial light sources are spatially distributed over the crop. Downstream light sources of the array of light sources produce a higher dosage of photosynthetically active radiation than light sources located further upstream as seen in the flow direction of the airflow guided over the crop.

A display module and a plant cultivation apparatus equipped with a display module are provided. The display module in which a control panel that controls a plant cultivation environment and an output that outputs a state of the plant cultivation environment are provided in a front surface thereof coupled to a structure of a bed and withdrawable and insertable into the plant cultivation apparatus together with the bed. The display module may be located at a front surface of the bed, so that usability and space efficiency may be increased.

A light source module for plant cultivation includes a first light source unit emitting a first type of light suitable for growing a plant, a second light source unit emitting a second type of light suitable for growing the plant, and a third light source unit emitting a third type of light suitable for increasing the content of phytochemicals in the plant. The first light source unit, the second light source unit, and the third light source unit are operated independently of one another. The first type of light and the second type light are visible light having different peak wavelengths. The third type of light includes at least one selected from among UVA, UVB, UVC, and near-UV light.

A plant cultivation light source includes at least two light sources selected from first, second, and third light sources that emit first, second, and third lights, respectively. The first light has a first peak at a wavelength from about 400 nanometers to about 500 nanometers, the second light has a second peak appearing at a wavelength, which is longer than the first peak, from about 400 nanometers to about 500 nanometers, and the third light has a third peak appearing at a wavelength, which is shorter than the first peak, from about 400 nanometers to about 500 nanometers. The first light is a white light and has a first sub-peak having an intensity lower than an intensity of the first peak at a wavelength from about 500 nanometers to about 700 nanometers. The first sub-peak has a full-width at half-maximum greater than a full-width at half-maximum of the first peak.

A method of providing light to plants. The method comprises providing a plurality of plants within a room, grouping each plant of the plurality of plants into one of a plurality of groups of plants based at least in part on a desired total light integral (“TLI”) for each of the plurality of plants and providing the corresponding desired TLI to each plant of the plurality of plants by sequentially providing light to each of the plurality of groups of plants during a time period. For each group of plants, each plant has a substantially similar photoperiod and a sum of the photosynthetic photon flux densities (“PPFDs”) of all plants in the group of plants is substantially similar.

The power barn system provides a way to eliminate greenhouse gas (GHG) emissions from livestock. The power barn system seals and traps the methane gas that is emitted from the livestock and converts the methane into electric power and carbon dioxide to enhance plant growth. The power barn system uses PV solar arrays and plastic sheeting to make sealed, airtight structure. The carbon dioxide is provided to greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby eliminating most greenhouse gas emissions from livestock. The power plant uses the methane at peak times at night while solar panels supply power during the day producing zero emission meat and 24/7 electricity at better than market rates.

The present disclosure relates to growing tray for a growth system, comprising a plurality of individual channels being distributed across a width of the growing tray and extending along a length of the growing tray. By means of the introduction of the channels it is possible to increase the yield of a crop to be grown at a growth substrate arranged on top of the channels. The present disclosure also relates to a growth system comprising a plurality of such growing trays.

A hanging planter and light assembly for growing a plant and illumination includes a plurality of a posts, which is engaged to and extends between a bottom plate and a top plate. A chain engaged to and extending from the top plate is engaged to an article of mounting hardware mounted to a surface to hang the hanging planter and light assembly. A bulb can be threadedly inserted into a socket, which is engaged to a lower face of the top plate. A power cord operationally engaged to the socket is used to operationally engage the socket to a source of electrical current. A pot can be inserted into an orifice, which is positioned in the bottom plate. A plant can be grown in the pot and the bulb can provide illumination to an area proximate to the hanging planter and light assembly.

The present invention concerns a solid nanocomposite material consisting of a polymer-matrix in which are dispersed alkali metal, hydronium or ammonium salts of polyanionic components, wherein the polymer-matrix comprises at least a linear or branched polymer or copolymer containing one or several poly(ethylene oxide) (PEO) chains, said polymer or copolymer being optionally crosslinked and each PEO chain having at least 4 ethylene oxide monomer units. The present invention relates also to a photonic, e.g. optoelectronic, device comprising such a nanocomposite material. Such material and device can be used as phosphorescence emitter, for crop growth lighting or for generating singlet oxygen.

Apparatus and methods for a hydroponics system with enhanced heat transfer are presented herein. By arranging the flow hydroponics system to have a series flow pattern via tubes and hydroponic pans, heat may be transferred from heat producing elements. The heat producing elements, including light emitting diodes (LEDs), may be thermally attached to the pans. The recycled heat can be transferred to the series circulating water supply for providing nutrient rich minerals at the roots of plants. Additionally, the heat can be transferred via the pans and without the need for costly fans or specialized heat sinks. In this way more space can be availed for the production of plants while recycling energy in the form of transferred heat.
