Also provided are methods of use of the system for measuring nitrogen in a plant and for identifying microbes capable of providing fixed nitrogen to a plant.

A system for vegetable garden and nursery cultivation of plants is described that includes a cabinet comprising a plurality of shelves on which to cultivate plants. The shelves are being positioned one on top of the other along a vertical axis, so as to identify a space interposed between the upper face of a shelf and the lower face of the overlying shelf. The space is adapted to cultivate the plants. Further, means for generating a light source, means for delivering a liquid, and means for suction/supply of a forced air flow are provided. Further, means for moving the shelves along the vertical axis are included, there being a control unit configured to control operation of the means for moving, the means for generating the light source, the means for delivering the liquid, and the means for suction/supply.

An indoor gardening appliance includes a liner defining a grow chamber, a grow module rotatably mounted within the grow chamber for receiving a plurality of plant pods, and a sealed system for regulating chamber temperature. A controller is configured for operating the sealed system to maintain the grow chamber at a grow temperature, obtaining a scheduled harvest time, determining a chill cycle including a predetermined chill time and a pre-harvest chill temperature based at least in part on the scheduled harvest time, and operating the sealed system to implement the chill cycle by regulating a chamber temperature to the pre-harvest chill temperature during the predetermined chill time.

The invention provides a method for sensing a plant-related parameter in a horticulture space (115), wherein (i) a radio transmitter (151) and a radio receiver (152) are arranged such that a radio path (153) between the radio transmitter (151) and the radio receiver (152) passes through at least part of the horticulture space (115), and (ii) the radio receiver (152) is configured in a radio signal receiving relationship with the radio transmitter (151), wherein the method comprises a sensing stage comprising: emitting a radio signal with the radio transmitter (151); detecting the radio signal with the radio receiver (152) and providing a related receiver signal; and determining the plant-related parameter based on the receiver signal.

Provided is a fan grow light. The fan grow light is configured to be mounted in a tent. The fan grow light includes a lamp board assembly and a fan assembly disposed on the lamp board assembly. The fan assembly is able to promote air circulation in the tent. The fan grow light can promote air circulation in the tent, enable plants to breathe better, inhibit molds, and promote plant growth.

A controller for an air supplier of an assembly line grow pod is provided. The controller identifies a plant on one or more carts; determines an airflow rate based on an airflow recipe for the identified plant; controls an air supplier to output air through one or more outlet vents at the airflow rate; obtains an image of the plant; identifies a type of contaminants deposited directly on the plant based on the obtained image; and adjusts a power of the air output from the air supplier to remove the contaminants from the plant by the air based on the identified type of contaminants deposited directly on the plant.

A fluid-cooled LED-based lighting fixture for Controlled Environment Agriculture (CEA) to improve energy efficiency, recycle waste heat, and support the operation of environmental sensors in a controlled agricultural environment. In one example, a lighting fixture frame mechanically supports and houses respective components of the lighting fixture and includes a light spine to mechanically couple the lighting fixture to a support structure. One or more coolant pipes formed from copper and coupled to the lighting fixture frame conduct a fluid coolant through the lighting fixture to remove heat. The lighting fixture comprises one or more LED modules to emit light, one or more onboard sensors and/or cameras, wireless communication functionality, and multiple electrical power and communication ports to facilitate interconnection of the lighting fixture in a variety of controlled agricultural environments. In some examples, the lighting fixture includes a multispectral imaging system to acquire multispectral images of the environment.

A refrigeration system is provided that can be used to cool a plant growth chamber. The refrigeration system can include a compressor to compress refrigerant, a condenser to condense refrigerant, a compressed refrigerant line running from the compressor to the condenser, a throttling device, a condensed refrigerant line running from the condenser to the throttling device, an evaporator to evaporate liquid refrigerant, a throttled refrigerant line running from the throttling device to the evaporator, an evaporated refrigerant line running from the evaporator to the compressor, and, a by-pass line connected to the compressed refrigerant line after the condenser and running to the evaporator. A hot gas proportional valve provided inline of the by-pass line and a liquid proportional valve provided inline of the condensed refrigerant line are used to control the flow of refrigerant through the by-pass line.

A structure having an area to be conditioned includes an air conditioning system having a heat exchanger and a condensate drain pan positioned adjacent to the heat exchanger such that a condensate will gravitate from the heat exchanger to the condensate drain pan. A system is associated with the area to be conditioned. The system is arranged downstream from and in fluid communication with an outlet of the condensate drain pan. The condensate from the condensate drain pan is deliverable to the system automatically.
