A method for controlling a balanced state of an assembly line grow pod is provided. A group of sensors including a pressure sensor and a weight sensor is arranged at a plurality of different locations of an assembly line grow pod. A first set of data indicative of weight of fluid supplied to plants supported in an assembly line grow pod is generated. A second set of data indicative of weight of plants grown is generated. Based on the first set of data and the second set of data, a weight disparity at a selected location of the assembly line grow pod is determined. Upon determination that the weight disparity exceeds a predetermined threshold, the balanced state of the assembly line grow pod is maintained by moving ballast water to reduce the weight disparity.
