A multi-source ground-to-air heat transfer system is configured to store thermal energy during a cooling/dehumidifcation mode of operation for future use during a heating mode of operation. The multi-source ground-to-air heat transfer system utilizes a ground loop that is configured under an enclosure, such as a greenhouse, and is in thermal communication with a thermal reservoir medium to conduct and store heat. A thermal exchange fluid is pumped through the ground loop and ground heat exchanger and may receive heat from a condenser during a cooling/dehumidification mode of operation and may liberate heat to the evaporator during a heating mode. The enclosure air may receive heat from the heat pump during a heating mode and may liberate heat to the evaporator during a cooling/dehumidification mode. The heat exchange system may employ a heat pump having a reversing valve to change the mode of operation.

A lighting system for a vertical farm can include a plurality of modules configured to be stacked and removably coupled physically and electrically to one another by at least one overhead robot. Each of the plurality of modules can include at least one physical and electrical connector. At least some of the modules can include one or more lighting elements.

The present utility model discloses a novel splicing type plant lamp which is provided with a power supply body and lamp bodies electrically connected with the power supply body, wherein first electrical assemblies are disposed on end portions of two ends of the power supply body correspondingly, and second electrical assemblies electrically connected with the first electrical assemblies are disposed on two ends of the lamp bodies correspondingly. The novel splicing type plant lamp has the beneficial effects that the problems of complex assembly and difficult disassembly of the plant lamp can be effectively avoided, and the transportation cost and labor intensity are reduced, so that the disassembly and assembly efficiency of the plant lamp is improved, the working efficiency is improved, the product competitiveness of the plant lamp is improved, and the efficiency of supplementing light to plants is improved. Different lamp bars can be freely combined, for example, the lamp body disposed on one side of the power supply body is composed of three lamp bars, and the lamp body disposed on the other side of the power supply body may be composed of four lamp bars, so that the plant lamp is suitable for different use scenes.

A method to grow cannabis is described, wherein the method includes providing and treating a source of water, mixing the water with an additive to form a liquid mixture, transferring the liquid mixture to a plurality of cannabis plants grown in a growing medium including a mycorrhiza fungus, and growing the cannabis using a humidity control method, then harvesting the cannabis plants. Trimming and grinding the cannabis along with use of environmental control methods including temperature, humidity, lighting schedules, and carbon dioxide concentrations are also described.

The present disclosure relates a plant cultivation apparatus and a water supply control method thereof. The plant cultivation apparatus may perform water supply, lighting, dehumidification and the like to cultivate a plant according to a cultivation condition corresponding to a cultivation stage and a type of the plant provided in a cultivation room.
