The increasing demand for leafy vegetables in urban areas has emphasized the need for sustainable and space-efficient farming practices. This study investigates the effects of organic Fish Amino Acid (FAA) fertilizer on the growth of lettuce (Lactuca sativa) using a vertical farming (VF) system. Lettuce seedlings were treated with varying concentrations of FAA fertilizer: 0 mL (control), 25.5 mL, 30.5 mL, and 35.5 mL per application. Growth parameters, including plant height and leaf count, were recorded over five weeks. The FAA was prepared via fermentation of catfish (Clarias spp.) waste with molasses. Results showed that lettuce treated with 30.5 mL FAA exhibited optimal growth with significant increases in height and leaf number compared to other treatments. The study concludes that FAA at 30.5 mL is a promising alternative to chemical fertilizers in enhancing lettuce growth under limited-space cultivation like VF systems.
