An integrated modular and scalable fogponics crop growth system for cultivating a crop includes an upper growth chamber housing a leafy portion of a crop, a lower growth chamber housing a root portion of the crop, a nutrient tank and dispenser, and an environmental system. The nutrient dispenser is coupled to the nutrient tank holding a nutrient mixture for sustaining the crop. The dispenser atomizes the nutrient mixture into a nutrient fog using a booster pump and a high pressure pump capable of generating approximately 800 PSI to 1500 PSI. The high pressure pump is operatively coupled to a nozzle configured to dispense the atomized nutrient fog, substantially between 6 microns and 15 microns droplet size, into the lower growth chamber. Temperature and humidity are separately controlled in the leaf area.
