A plant cultivation device includes a light source unit having a first light source emitting stimulation light in a UV region toward a plant and a second light source emitting background light toward the plant, the background light having a different peak wavelength than the stimulation light. The second light source emits the background light during a light period and stops emission of the background light during a dark period. In addition, the first light source emits the stimulation light for a certain period of time during the light period. Further, a cumulative amount of the stimulation light emitted from the first light source is 0.036 J or more per day.

An annular LED grow light is disclosed, which comprises a radiator, a light source board, and a power supply box. The light source board is composed of a PCB light board and a plurality of LED lamp beads, wherein the LED lamp beads are arranged on the PCB light board in an annular array about a center. The beneficial effects of the present disclosure are: the photosynthetic photon flux density (PPFD) is distributed more evenly after the LED lamp beads are arranged in an annular array about the center, thus the effective irradiated area is larger, and the cost has been saved.

An air movement system for plant cultivation. An air conditioner receives a gas mixture of air and carbon dioxide, regulates a temperature of the gas mixture, and outputs the gas mixture at the regulated temperature. A first bladeless fan receives the gas mixture output by the air conditioner and supplies the gas mixture as an air flow to a first crop area at a velocity towards an air intake. At least one second bladeless fan assists the air flow from the first crop area to a second crop area so as to maintain the velocity towards the air intake.

Provided is a sunlight lighting system used in a greenhouse or a plant factory. The sunlight lighting system converts sunlight into light with a stable illumination direction and a controllable illumination intensity by means of a combination of a controller, a light condenser, a main driving mechanism and an illuminator, so that the sunlight lighting system meets lighting requirements of high-density stereoscopic cultivation frames. A supporting greenhouse is further comprised, where a facade or a top is provided with a light through hole. A main optical axis of the sunlight lighting system passes through the light through hole. A supporting lighting method is further comprised, which can obtain a better lighting effect with fewer steps.

A growing environment control system includes a house environment control device that controls a surrounding environment of plants under cultivation in an agricultural house, and a parameter management device that creates and provides template parameter information including environment parameter information used by the house environment control device and pertaining to control of the surrounding environment, and identification information pertaining to content or an attribute of the environment parameter information and used for identifying the environment parameter information.

The present invention is a scalable and re-configurable system for indoor growing. The scalable and re-configurable system for indoor growing is comprised of a plurality of growing sleds, in which each growing sled has a plurality of plant stations. Plants are grown in receptacles on each plant station. The plant station is rotated by a drive system. Each plant station provides irrigation. Each plant station has a forced frame connected to the top of a plant support assembly. A forced frame is used to confine each plant to a known foot-print. This is necessary in indoor growing in order to make the production uniform and efficient.
