Urban Farm DB summary

An experimental study in the Zamboanga Peninsula investigated the economic feasibility of hydroponic lettuce production using Fermented Plant Juice (FPJ). Estrosa and Olmetie lettuce varieties showed optimal performance, with undetectable nitrate levels in Estrosa and Green Wave, and all varieties remaining within international safety limits for nitrate. Cadmium was not detected.
