Urban farming and controlled-environment agriculture have become critical strategies for sustainable food production. This study investigates the effects of overexposing blue and purple LED light on the growth of Brassica rapa (petchay) and Ipomoea aquatica (water spinach) under controlled outdoor conditions. The research evaluated plant height, number of leaves, leaf length, and leaf width across three lighting treatments: natural sunlight, blue LED, and purple LED. Using one-way ANOVA and post
