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. The T-shaped mister provides circumferential coverage of the plant roots, while the aeration of the plant nutrient solution provides an aerated solution that accelerates plant growth through a hybrid process of Nutrient Film Technique (NFT) called a Hyperactive Aeroponic Shallow Water Culture (HAS Culture). Several interconnected aeroponic growing units may be stationed in a parallel grid to provide ample space for rapid growth of crops, while supplying the water and nutrient solution through a network of pipes and tubes between units.
