This study investigated the viability of a low-cost hydroponic system for food security in the Zamboanga Peninsula, employing a descriptive design. The research assessed the acceptability, growth performance, and economic feasibility of hydroponic lettuce production using locally sourced organic inputs, specifically Fermented Plant Juice (FPJ). Hydroponics lettuce production is technically feasible and economically viable in urban and peri urban areas of the Zamboanga Peninsula. It highlights high public acceptability, recognizing hydroponics as a sustainable solution for spatial and food security challenges. Recommendations for the Zamboanga Peninsula include agricultural modernization through technical training, start-up assistance, material accessibility, and R&D support. Public awareness campaigns for low-cost hydroponics using FPJ, crop diversification, farmer engagement, and urban/peri-urban adoption incentives are also suggested. Growers are advised to prioritize Estrosa and Green Wave for lower nitrate uptake and ensure correct FPJ preparation.
