A control system for controlling humidity in an indoor growing environment is provided, which includes software to control the removal of moisture by using current Vapor Pressure Deficit (VPD) as measured in the indoor air space of a grow room in comparison to a target Vapor Pressure Deficit. The temperature and relative humidity in various areas of the grow room are monitored and used by the software to calculate the current VPD and determine a preferred profile for the target VPD. The control system is configured to maintain consistent VPD with moisture removal by a dehumidifier in response to temperature variations throughout a night/day cycle and through successive growth stages to ensure optimal plant growth and transpiration rates.

An integrated modular and scalable fogponics crop growth system for cultivating a crop includes an upper growth chamber housing a leafy portion of a crop, a lower growth chamber housing a root portion of the crop, a nutrient tank and dispenser, and an environmental system. The nutrient dispenser is coupled to the nutrient tank holding a nutrient mixture for sustaining the crop. The dispenser atomizes the nutrient mixture into a nutrient fog using a booster pump and a high pressure pump capable of generating approximately 800 PSI to 1500 PSI. The high pressure pump is operatively coupled to a nozzle configured to dispense the atomized nutrient fog, substantially between 6 microns and 15 microns droplet size, into the lower growth chamber. Temperature and humidity are separately controlled in the leaf area.

The present disclosure discloses a water recycling type greenhouse, including a greenhouse body; a water collection device is arranged in the greenhouse body; the water collection device is provided with an air inlet and an air outlet; a condensation portion and a reheating portion are arranged in the water collection device; and the water recycling type greenhouse further includes an energy supply system. Air in the greenhouse body can be poured into the water collection device from the air inlet, flow through the condensation portion and the reheating portion in sequence, and finally be discharged into the greenhouse body again from the air outlet. When the heated air is discharged into the greenhouse body again, a decrease of the temperature of the greenhouse is not likely to occur, and normal growth of plants is not easily affected.

An indoor gardening appliance includes a grow module rotatably mounted within a liner to at least partially define a first grow chamber and a second grow chamber. A climate control system includes an evaporator plenum housing an evaporator, a fan assembly for urging air through the evaporator plenum, recirculation ducts for independently circulating air through the first grow chamber and the second grow chamber, and ambient duct systems for independently circulating fresh ambient air through the first grow chamber and the second grow chamber. A system of dampers selectively opens or closes each respective recirculation duct and ambient duct system for independent climate control of the first grow chamber and the second grow chamber.

A multi-stage plant cultivation system for and method of enhancing plant production efficiency is disclosed. For example, a multi-stage plant cultivation system and method may provide a vegetation module and multiple growing modules arranged sequentially and wherein the full growing life cycle of a plant may be perform within the modules. In one example, the multi-stage plant cultivation system and method may provide a vegetation module and multiple growing modules that may further include a plant transport system, one or more air handler systems, one or more lighting systems, one or more water delivery systems, one or more wastewater systems, and a controller.

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.

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.
