In India, cultivation methods for optimizing lettuce production on household balconies were compared: circulating hydroponics, static hydroponics, and substrate cultivation against soil cultivation as a control, evaluating growth, yield, and quality. Hydroponic systems significantly outperformed soil cultivation. Static hydroponics produced the highest biomass, with fresh and dry weights increasing by 10.53% and 55.29% over the control. Circulating hydroponics had slightly lower yield but increased vitamin C content by 6.57% and sensory quality by 41%, ranking second overall. Substrate cultivation showed moderate gains, with vitamin C up 5.14% and taste rating up 19.66% versus the control. Considering growth performance, space efficiency, ease of management, and cost, static and circulating hydroponics were identified as the most suitable systems for balcony-based lettuce cultivation.
