With global population growth and limitations in traditional agriculture, innovative solutions like vertical hydroponic farming are essential to sustainably meet food demand. Despite the potential of vertical farming, few studies have specifically optimized multi-layer, nutrient film technique (NFT) systems for leafy vegetable production in urban areas. This study addresses this gap by developing a multi-layer A-frame NFT hydroponic system tailored for basil (Ocimum basilicum) cultivation in urban settings. Constructed from galvanized iron and food-grade PVC, the structure supports 153 plants within a compact 3.9 m2 area with five vertical layers, achieving a plant density 5.46 times higher than conventional methods. Trials produced a basil yield of 2.89 kg/m2 and a water use efficiency of 56.4 kg/m3, showcasing both high productivity and resource efficiency. This system enables urban farmers to grow fresh greens locally, reducing transportation cost and carbon emissions, and advancing sustainable agriculture.
