Abstract: Growing devices, systems and methods for promoting growth of seedlings may include at least one energy output device; at least one growing environment that includes a first growing environment; a nutrient solution container within the first growing environment, the nutrient solution container for supporting seedlings during growth; at least one growth assist device (GAD) associated with the first growing environment; and a controller. The controller may generate consumption data regarding operation of the at least one GAD and generation data regarding operation of the at least one energy output device. The controller may determine, based on at least one predetermined constraint, as well as consumption data and generation data, a consumption-generation plan and may control energy output to at least one GAD based on the determined consumption-generation plan. The controller may control energy generation, by at least one energy output device, based on the determined consumption-generation plan.
