The spectrum and intensity of light are very influential in the process of plant growth, because the spectrum of color and intensity of light helps the process of photosynthesis. This study aims to examine the effect of the red and blue color spectrum and the intensity of LED lamps with 3 watts, 9 watts, and 15 watts of power on the growth of microreens which include many stems, many leaves, and height. Microgreens are small and soft plants that can be harvested in a short time of 7-14 days after planting seeds. This study uses the type of experimental research. There were two groups in this study, namely the control experimental group which only used direct sunlight without the aid of LEDs and the experimental group which was given the LED spectrum and LED light intensity exposure. The samples used were 140 samples of pakcoy seeds which were divided into 20 samples for the control group and 120 samples for the experimental group. The data analysis technique used was SPSS 23 with Two Way Anova test. The results of the data analysis technique, namely the spectrum and intensity of LED light affect the growth of microreens pakcoy.
