Abstract: Systems, methods and computer-readable media are provided for controlling environmental conditions to control latent and sensible loads in a plant grow chamber. The density of plant receptacles in the grow chamber is such that, when plants are held in the plurality of plant receptacles, evapotranspiration contributes to the latent load so that the latent load exceeds a sensible load, resulting in evapotranspirative cooling. This shift in the energy balance allows for greater energy savings, as compared with conventional indoor farms that focus on removing heat from the growth environment. Environmental conditions may be controlled to achieved desired conditions, such as the optimum ratio of harvest weight yield to energy consumption under given constraints.

Abstract: Systems, methods and computer-readable media are provided for controlling environmental conditions to control latent and sensible loads in a plant grow chamber. The density of plant-0 receptacles in the grow chamber is such that, when plants are held in the plurality of plant receptacles, evapotranspiration contributes to the latent load so that the latent load exceeds a sensible load, resulting in evapotranspirative cooling. This shift in the energy balance allows for greater energy savings, as compared with conventional indoor farms that focus on removing heat from the growth environment. Environmental conditions may be controlled to achieved desired conditions, such as the optimum ratio of harvest weight yield to energy consumption under given constraints. Light modules for enabling plant growth suitable for controlled environment agriculture are also described.
