The conversion of arable land threatens humans’ nourishment and nutrition fulfillment. On the other hand, society’s food consumption pattern finds an increase in processed food consumption as agricultural industrialization develops. This could cause health issues related to the increase of oxidative stress in human bodies. A potential approach of this issue is by providing food that can be produced and accessed in the center of residential areas, which may play a role in maintaining health, such as microgreens. This production process is determined by plant exposure to a suitable combination of red and blue light in place of sunlight. This research aims to produce wheatgrass microgreens through urban farming method and application of artificial lighting. This research analyzes the effects of combinations of red and blue light on the growth and flavonoid content of wheatgrass microgreens. Flavonoid is a compound that is believed to be capable of reducing oxidative stress. The main variables of this research is fresh mass and flavonoid content. Results show that white fluorescent light as the control has more significant impact on the fresh mass of wheatgrass microgreens, whereas a combination of 83% red light and 17% blue light gives more significant impact on the flavonoid content.
