Recently, studies have been actively conducted on light sources which can affect the growth rate of plants by using monochromatic lights which have light wavelength or combining them into mixed lights. The studies measure Photosynthetic Photon Flux Density (PPFD) according to the change of light quality of LED light source and research on the acceleration of plant growth. With red, blue, green and white mono-chromatic lights, this study fabricated 6 mixed lights. Then, with 3 mono-chromatic lights and 6 fabricated mixed light source, the study conducted comparison analysis on what effect optical properties and PPFD have on (the growth of) a plant (radish sprouts). As the result of analysis, in the same PPFD, it turned out that the speed of plant growth was faster in red mono-chromatic lights while the speed was similar in blue and white mono-chromatic lights and mixed lights.
