Green onion cultivation through vertical farming on aeroponic towers provides an efficient method to maximize yields. Green onions, also known as scallions or spring onions, thrive in a wide range of climates and are relatively fast-growing. Optimal growth occurs at temperatures between 55 to 75°F (13 to 24°C), but they can tolerate colder temperatures. #springonion #greenonion #scallions #farming #agriculture #aeroponics #gardening #hydroponics
