Abstract: Aeroponics apparatus is disclosed, which includes a grow bed tray having a base and at least two side-walls, the grow bed tray being able to hold a plant support at a position spaced from the base of the grow bed tray, and a nebulizer for nebulizing nutrient solution, the nebulizer located at the base of the grow bed tray and comprising an ultrasonic transducer and a holder for holding the ultrasonic transducer. Also disclosed is a method for crop production using the aeroponics apparatus by either flowing nutrient solution into the base of the grow bed tray to contact at least the roots of the crops or providing nutrient solution at the base of the grow bed tray and nebulizing the nutrient solution so that the nebulized nutrient solution contacts at least the roots of the crops.
