Abstract

The plant factory controls temperature, lighting, plant nutrients, and other environmental factors to provide a consistent, plant-friendly environment for predictable yields. In addition, microgreens can be grown profitably in expensive urban plant factories in a short harvest period. This study uses hydroponics with artificial lighting in the form of a Light-Emitting Diode (LED) with different ratios of lux and Photosynthetic Photon Flux Density (PPFD), i.e., 100 lx and 44.26 mol∙m⁻²∙s⁻¹ PPFD for 100% blue; 600 lx and 20.32 mol∙m⁻²∙s⁻¹ PPFD for 100% red; 1000 lx and 95.92 mol∙m⁻²∙s⁻¹ PPFD for 100% white, with maintained 25–27 ℃ of temperature and 70–80% of relative humidity. Microgreens of red and green lettuce were watered once a day with 250 ppm of plant nutrients using a commercial AB mixture and liquid organic fertilizer. The LED light, plant nutrient, and lettuce variety utilized in this study significantly affected the plant height, color parameters of L*, a, and b, and chlorophyll content of SPAD chlorophyll, chlorophyll a, chlorophyll b, and total chlorophyll content seven days after planting, as determined by the three-way MANOVA and Duncan test. A PCA model with two PCs has 88.0% of the explained variables for a comprehensive analysis of the LED data's variability.
