An aeroponic growth system comprising a plurality of modular aeroponic units each including at least one spray nozzle directed into a root zone； a lighting system associated with the plurality of the modular units and configured for emitting light in a vegetative zone； a pressurized reservoir configured for housing a nutrient containing fluid； and a nutrient feeding system configured for fluidly and selectively connecting each of the modular units to the pressurized reservoir in parallel, wherein the nutrient feeding system includes a pressure stop valve associated with each of the modular units. When one of the modular units are disconnected to the associated pressure stop valve, the pressure stop valve is configured for preventing the fluid from flowing from the pressurized reservoir through the pressure stop valve, and the other modular units connected to the nutrient feeding system remain fluidly connected to the pressure reservoir.
