Abstract: A plant-growing-train system includes at least one convoy of maneuverable growing units, at least one centralized resource station that contains a high-intensity lighting system, and a water and nutrients delivery system. The convoy is transported to the resource station in order to expose the plants to optimal levels of light, water, and nutrients. Because the lights are high-intensity, the required amount of time plants must be exposed to light is reduced, enabling grow units to share lights and other resource infrastructure rather than having lights dedicated uniquely to each unit and resources delivered to each unit. This system substantially reduces the amount of equipment and expense required to grow plants in a controlled environment.
