Abstract

A growth system for growing vegetation is provided, and includes a plurality of modular growing units defining a vegetative zone; a plurality of lighting units including a lighting node for selectively emitting first and/or second wavelengths of light in the vegetative zone; an unpressurized reservoir for housing a fluid containing one or more nutrients; a nutrient feeding system for fluidly connecting each of the modular units to the reservoir in parallel; and a pump in fluid communication between the reservoir and the modular units. When a modular unit is connected to the respective quick connect valve, the nutrient feeding system directs the fluid to the modular unit, and when the modular unit is disconnected from the valve, the valve is configured for preventing the fluid from flowing from the reservoir through the valve, and the other modular units connected to the nutrient feeding system remain fluidly connected to the reservoir.
