Provided is a greenhouse plant growth monitoring system. The system includes a master controller, an external monitoring module, an internal monitoring module and an external circulation device. The external monitoring module is disposed outside a greenhouse, and is configured to monitor an external environment of the greenhouse and output an external environment monitoring signal. The internal monitoring module is disposed inside the greenhouse, and is configured to monitor an internal environment of the greenhouse and output an internal environment monitoring signal. The master controller includes an external environment signal input terminal, an internal environment signal input terminal and an external circulation control signal output terminal. The external environment signal input terminal is connected to an external monitoring signal output terminal of the external monitoring module. The internal environment signal input terminal is connected to an internal monitoring signal output terminal of the internal monitoring module.

Air handling system for a climate control system in a housing that includes at least a delimited space with controlled environment, CE space. The air handling system includes an air handling unit, AHU, a pipe system and a perforated plate assembly. The pipe system includes a branched tree-like structure of conduits, that branches in the direction from the air handling unit towards the perforated plate assembly for homogenous distribution of air over the perforated plate assembly such that the air flow through the perforated plate assembly into the CE space is an air flow under laminar flow conditions. Also, a climate system for climate control in such a delimited space, a modular unit including such a delimited space and such a climate system, and an assembly of modular units.

A plant growing apparatus irradiates plants by switching white light from a white light source into light of a color of a specific wavelength by using a partition plate that partitions a light source placement space and a plant growing space. The plant growing apparatus includes: a white light source emitting white light and being provided to face plants to be grown; a light source placement space to place the white light source; and a plant growing space to place the plants to be grown; a housing facility blocking entry of external light; and a partition plate that extends in the housing facility in a horizontal direction, and includes a filter blocking at least one of temperature transfer and air circulation between the light source placement space and the plant growing space, and transmitting light of a specific wavelength in the white light from the white light source.

A mushroom growing appliance includes a grow chamber defined within a cabinet and a climate control system for regulating the humidity and gas concentrations within the grow chamber. The climate control system includes a water reservoir positioned within the grow chamber for receiving water, a wicking filter positioned at least partially within the water reservoir for wicking the water into the wicking filter, a recirculation fan positioned adjacent the wicking filter for selectively urging a flow of recirculation air through the wicking filter and back into the grow chamber, and a fresh air fan positioned adjacent the wicking filter for urging a flow of fresh air through the wicking filter and into the grow chamber.

Portable ground cover devices, kits, and methods of assembly and use. A ground cover device includes a frame that may be assembled to a size suitable for use to cover a garden. A cover may be attached to the frame such that the cover is within an interior of the frame when assembled. When in an expanded configuration, the device may be placed over the garden to encourage plant growth and protect the garden from adverse weather, wildlife, and other environmental stressors. The device may be transitioned from the expanded configuration to a retracted configuration for storage or transport of the device when not in use.

A stabilizer mixture containing a sterically hindered amine light stabilizer and a triazine UV absorber in a specific ratio.

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.
