This study evaluated the production performance of lettuce (Lactuca sativa L. var. Lalique) using organic nutrient solutions in a non-circulating hydroponic (Kratky) system. The experiment was conducted in a polyhouse at Camiguin Polytechnic State College, using a Randomized Complete Block Design (RCBD) with seven treatments: SNAP (synthetic control), Water (negative control), Vermitea, VegeGrow, Ramils, Biovoltin, and Healthynest. Growth parameters, yield components, nutrient solution consumption, sensory attributes, and profitability were assessed. Results indicated that Ramils (T5) and Healthynest (T7) performed comparably to SNAP (T1) in plant height, leaf width, canopy diameter, root development, and yield while also exhibiting high sensory quality and marketability. In contrast, T3 (Vermitea), T4 (VegeGrow), and T2 (Water) showed suboptimal performance, reflecting variability in organic fertilizer efficacy. The findings suggest that select organic nutrient solutions can be a viable alternatives to synthetic fertilizers in hydroponic lettuce production. However, further refinement of organic formulations is needed to improve stability and nutrient bioavailability. Further research is needed to assess long-term agronomic, economic, and environmental impacts. This study contributes to sustainable agriculture by supporting the integration of organic fertilizers into hydroponic systems.
