An aeroponic growing system, double T-shaped sprayer design and method for cultivating larger plant crops and increasing harvest frequency. The system comprises a series of aeroponic growing units, each of which supports a plant's roots within an enclosure. The enclosure houses a sprayer, an interior volume of plant nutrient solution and a plumbing system for accepting and distributing the aqueous water-nutrient solution. The internal sprayer is a double T-shaped mister that sprays an atomized mist directed from a first set of nozzles onto the plant roots, along with a second set of nozzles directed toward the base of the enclosure to aerate the interior volume of plant nutrient solution.
