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 structures. The carbon dioxide is provided to one or more sealed greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby completely eliminating 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 and 24/7 electricity at better than market rates.

The invention relates to a light-diffusing material, having a high transmission of UVA light, useful for horticultural lighting. The light-diffusing material has a hiding power of greater than 50% at 350 nm and a transmission of light at 350 nm of at least 30 percent, and preferably at least 50%. Additionally the light-diffusing material also transmits and diffuses at least 50% of light at 300 nm, 465 nm, and at 800 nm. The light-diffusing material is especially useful as a glazing for horticultural use.

The light emitting device emits light having a ratio R/B of a photon flux density R to a photon flux density B ranging from 2.0 to 4.0 and a ratio R/FR of the photon flux density R to a photon flux density FR ranging from 0.7 to 13.0, the photon flux density R being in a wavelength range of 620 nm or more and less than 700 nm, the photon flux density B being in a wavelength range of 380 nm or more and 490 nm or less, and the photon flux density FR being in a wavelength range of 700 nm or more and 780 nm or less.

An aeroponic system for supporting efficient low-resource-usage plant growth comprises a housing comprising one or more openings and one or more root chambers; one or more sealing members configured to substantially conform to a stalk of a plant and to substantially isolate a canopy of the plant from the one or more root chambers; one or more root chamber sensors; one or more nutrient storage reservoirs for storage of plant nutrients; one or more air-assisted nozzles configured to introduce atomized nutrient solution into the one or more root chambers; a temperature control system configured to control a temperature of the one or more root chambers; and a control system configured to control the temperature control apparatus and the one or more air-assisted nozzles to maintain environmental parameters associated with the one or more root chambers within desired parameter ranges.

Plants are optimally grown under artificial narrowband Photosynthetically Active Radiation (“PAR”) of multiple colors, and color palettes, applied in but partially time-overlapping cycles. As well as a long, growing season, cycle, the colored lights are cyclically applied on a short, diurnal, cycle that often roughly simulates a peak-season sunny day at the earth latitude native to the plant. Bluer lights are applied commencing before redder lights, and are likewise terminated before the redder lights. Infrared light in particular, is preferably first applied at a time corresponding to early afternoon, and is temporally extended past a time corresponding to sunset. The colored lights and light palettes preferably rise to, and fall from, different peak intensities over periods from 10 minutes to 2 hours, and relative peak intensities of even such different colors as are used at all vary up to times two (×2) in response to differing PAR requirements of different plants. Computer-controlled colored LED lights realize all.

A light device for plant cultivation is disclosed. The light device for plant cultivation includes a light source unit including multiple first light source modules and multiple second light source modules. The multiple first light source modules and the multiple second light source modules may emit light for plant cultivation toward a plant. The multiple first light source modules are arranged at constant intervals. The multiple second light source modules are disposed at least between a pair of first light source modules disposed at both ends of the light source unit.

Storage, growing system and methods for storing, germinating, propagating and or growing living organisms, exemplary systems including stackable growth tray(s) containing: a drainage system, the drainage system including: an inclined growing surface, inclined in a direction to at least one drainage hole; a drainage routing structure positioned over the at least one drainage hole, and having a down-pipe and a connecting routing pipe, wherein the down-pipe is for receiving fluid from an adjacent-above stackable item and transmitting the fluid to an adjacent-below down-pipe or a drain-pipe, and the connecting routing pipe is for receiving fluid from an adjacent-above drainage hole and routing the fluid to the down-pipe, and wherein fluid propagating from the inclined growing surface or an adjacent-above stackable item is directed through the growth tray to a down-steam point in the drainage system.

A pole system for racking, storing, germinating, propagating and growing living organisms on a growth tray, the pole system including: a substantially vertical support structure, the support structure including at least one utility system for supporting propagation or growth of a living organism; one or more vertically-spaced interface positions, each for interfacing with a growth tray; and one or more openings in the support structure, corresponding to one or more of the interface positions, for providing services to interfaced growth tray(s) is disclosed. Further, a hydroponic system and method using the pole system are disclosed.

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 hydroponic growing system is presented. The system can include multiple growing trays in a vertical arrangement, where a pump supplies the top-most tray and each lower tray is supplied by the overlying tray, and where the plumbing elements for supply and drainage are arranged to one side of the system. The system includes variations to support different crop types within the same system, including removable growing structures for root vegetable, microgreens and supports for vining crops. The system can monitor and adjust the nutrients and other features of the systems water profile to concurrently group multiple crops in differing developing stages.
