A gardening apparatus includes one or more of a base, a fluid reservoir, and a plant tray or support disposed on the reservoir. The support is adapted for receiving one or more modular plant inserts, and can define a flow structure for channeling fluid to each insert. A pump supplies fluid from the reservoir to the plant tray or support, with a light assembly adapted to generate a spectrum of light for growth of plants from the inserts. A processor is configured for controlling fluid flow from the pump, the light spectrum generated by the lighting elements, or both. For example, the processor can use a dynamic recipe, algorithm or control schedule to modulate the fluid flow or spectrum based the plant type, growth stage, height, plant health data, digital phenotyping data, or ambient conditions, or a combination thereof.

A vegetable production method includes seeding, causing a cotyledon to sprout from a seed in a first period, growing a vegetable in a second period subsequent to the first period, further growing the vegetable in a third period subsequent to the second period, and harvesting the vegetable. The vegetable is grown with first light having a first maximum value of a light intensity in a wavelength range of 420 to 490 nm and including at least portion of light in a wavelength range of 500 to 600 nm in a later part of the second period, and is grown with second light having a second maximum value of a light intensity in a wavelength range of 590 to 650 nm, having a peak light intensity less than the second maximum value in a visible light wavelength range of less than or equal to 500 nm.

Solid-state lighting devices and more particularly light-emitting devices for horticulture applications are disclosed. Light-emitting devices are disclosed with aggregate emissions that target chlorophyll absorption peaks while also providing certain broader spectrum emissions between the chlorophyll absorption peaks. The aggregate emissions may be provided by light-emitting diodes (LEDs) that emit wavelengths that correspond with certain chlorophyll absorption peaks and lumiphoric materials that provide broader spectrum emissions. The aggregate emissions are configured to have reduced emissions from lumiphoric materials in ranges close to certain chlorophyll absorption peaks, such as above 600 nanometers (nm). In this regard, light-emitting devices according to the present disclosure provide the ability to efficiently target specific chlorophyll absorption peaks for plant growth while also providing suitable lighting for occupants in a horticulture environment.

A photo-selective light spectrum-modifying net for use in citrus fruit production, the net comprising a woven array of parallel and mutually spaced first threads and an array of parallel and mutually spaced second threads, the second threads being inclined to the first threads to define an array of openings between the first and second threads, wherein the first threads are uncolored and composed of a first polymer which is selected from a polymer incorporating a white pigment or dye, a transparent polymer or a translucent polymer, and the second threads are colored red and composed of a second polymer which incorporates a red pigment or dye, the second threads being adapted to transmit, scatter and reflect electromagnetic radiation in the wavelength range of from 640 to 680 nm. Also disclosed is a method of producing citrus fruit using the net.

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.
