The network communications ports of the respective lighting fixtures are coupled together with a plurality of waterproof network communications cables. In one example, a lighting system kit comprises two or more lighting fixtures having an AC power port comprising an industrial type connector. The kit further comprises multiple industrial power cables and one or more industrial drop tee cables.

The present invention discloses a telescopic LED grow light, which comprises a power supply box, a power supply holder, a plurality of lamp bodies and a telescopic frame, wherein the power supply box is located in a middle of the LED grow light, two power supply holders are respectively fixed at both ends of the power supply box, the power supply holder is also used for fixing the lamp bodies located at both sides of the power supply box, and the lamp bodies are fixed by the telescopic frame for expanding or contracting. The present invention has the beneficial effects that the PPFD value is changed by adjusting the telescopic function of the grow light. The function of the grow light that can be retracted and reduced for storage is very practical, in addition, it is also convenient for transportation after contraction.

A lighting device is presented. The lighting device includes an LED light source; and a red/far-red emitting phosphor radiationally coupled to the LED light source, wherein the red/far-red emitting phosphor comprises a host material activated with an activator ion, and wherein the activator ion comprises at least one of Sm.sup.2+ and Mn.sup.2+. Numerous other aspects are provided.

A gardening appliance includes a liner positioned within a cabinet and defining a grow chamber, and a grow tower is positioned within the grow chamber and includes a module support frame including a plurality of vertical support members a plurality of mounting slots. A grow module defines a support body defining a plurality of apertures for receiving one or more plant pods, the grow module further including a plurality of mounting tabs configured for receipt within the plurality of mounting slots to removably mount the grow module to the module support frame.

An apparatus for controlling conditions in a plant cultivation facility includes a lighting system arranged in connection with plants present in an environmentally sealable and closable cultivation facility; a hydronic cooling arrangement for lowering or impeding the rise of temperature in the cultivation facility, the cooling arrangement comprising a cooling manifold present in connection with plants in the cultivation facility and a heat recovery arrangement for utilizing excess heat generated in the cultivation facility. The heat recovery arrangement includes a heat storing system. The heat recovery arrangement includes one or more condenser dryers/coolers for collecting water and/or heat absorbed in the indoor air of a cultivation facility and a heat pump assembly for transferring the heat, accumulated in the heat storing system by way of the cooling arrangement's circulation water and/or the condenser dryer's/cooler's circulation water, into an independent secondary circuit.

The invention provides a horticulture lighting arrangement (1000), comprising (i) a lighting system (100) configured to provide horticulture light (101) having a controllable spectral power distribution, and (ii) a control system (300) configured to control the spectral power distribution of the horticulture light (101); wherein in an operational mode of the horticulture lighting arrangement (1000) the horticulture lighting arrangement (1000) is configured to provide the horticulture light (101) according to an on-off schedule wherein consecutively an on-period (D) and an off-period (N) are applied, wherein:—the horticulture light (101) comprises one or more of first horticulture light (1011) comprising a wavelength selected from the range of 400-600 nm, red light (1012) comprising a wavelength selected from the range of 600-700 nm, and far-red light (1013) comprising a wavelength selected from the range of 700-800 mn;—the on-period (D) lasts in in the range of 12-20 hours and the off-period (N) lasts in the range of 4-12 hours, wherein the on-period (D) comprises an end-of-day period (EOD) at the end of the on-period (D), wherein the end-of-day period (EOD) lasts in the range of 0.5-4 hours;—wherein during a substantial of the on-period (D) before the end-of-day period (EOD) a R/Fr ratio, defined as a ratio I600-700 nm/I700-800 nm of red light (1012) and far-red light (1013), is selected from the range of 4-20, and during a substantial part of the end-of-day period (EOD) the R/Fr ratio is selected from the range of 0.1-4.

A plant growing system including a plant growing apparatus and methods of making and using the plant growing apparatus to control at least one physical condition of the environment to cultivate plants in plant growing trays associated with the plant growing apparatus.

A modular hydroponics gardening apparatus for growing plants without soil includes a water pump in communication with a water source for pumping fluid upwardly through a transfer conduit. The water pump and a lower end of the transfer conduit is positioned in a watertight base member. The apparatus includes growth pods arranged radially inside a midsection member that defines spaced apart apertures, each defining an open end in communication with a respective aperture. A plurality of midsection members may be stacked atop one another. A lid assembly is stacked atop the uppermost midsection member, the transfer conduit extending upwardly from the water pump to the lid assembly where water is pumped and rains down into respective growth pods. An ultraviolet light extends about each midsection and is vertically adjustable for shining its light into respective growth pods. With a timed water supply and controllable light emissions, plant growth is maximized.
