Background: National Pakcoy (Brassica rapa L.) production declined by approximately 9.69 % from 2022 to 2023 due to climate variability, suboptimal cultivation practices, and agricultural land-use conversion, highlighting the need for alternative production strategies. Wick-based hydroponic cultivation with optimized nutrient management using AB Mix and Gandasil D foliar fertilizer is therefore investigated for its potential to enhance nutrient uptake efficiency, vegetative growth, and yield of pakcoy in a sustainable manner. Methodology: the study conducted in Gubeng District, Surabaya, utilized a factorial Completely Randomized Design (CRD). The first factor was AB Mix concentration (500 ppm, 1000 ppm, 1500 ppm), and the second was Gandasil D foliar fertilizer concentration (Control, 1 g/L, 2 g/L, 3 g/L). Observation parameters include, plant length (cm), leaf area (cm²), total fresh weight, shoot fresh weight, and shoot dry weight. Further analysis was performed using the Honestly Significant Difference (HSD) test at a 5% significance level. Findings: showed a significant interaction between the AB Mix concentration and Gandasil D foliar fertilizer on the plant shoot dry weight, with the highest yield (6.27 g) achieved by the combination of 1500 ppm AB Mix and 2 g/L Gandasil D. The single treatment of 1500 ppm AB Mix concentration yielded the best average for all observed parameters, including: plant length (16.73 cm), leaf area (688.04 cm²), total fresh weight (64.15 g), shoot fresh weight (51.56 g), and shoot dry weight (6.27 g). The 2 g/L Gandasil D concentration treatment provided the highest results for total fresh weight (56.09 g) and shoot fresh weight (45.28 g). The combination of 1,500 ppm AB Mix and 2 g/L Gandasil D demonstrated the most optimal results for the growth and yield of pakcoy plants compared to other treatment combinations. Contribution: These findings provide information regarding the selection of the optimal AB Mix and Gandasil D concentrations to maximize the growth and yield of pakcoy in the wick hydroponic system, which can be utilized in educational or training programs for communities practicing urban farming
