Kangkung microgreen growth analysis under T5 LED lighting using solar PV

Abstract

The T5 LED lamp is one form of LED light that can be utilized for indoor microgreen growing. The T5 LED lamp has various advantages, such as great energy efficiency and a long lifespan, and they do not emit excessive heat. This research intends to analyze the growth rate of kangkung (Ipomoea reptans poir) utilizing a T5 LED lamp as the light source. The research was carried out through an experimental design. Kangkung microgreen plants were placed under a T5 LED lamp, positioned 50 cm below the lamp’s surface, and connected to the voltage output supply from solar PV. The results showed that the average value of root growth rate was 26% per day, stem length growth rate was 26% per day, leaf width growth rate was 3.74% per day, leaf length growth rate was 23% per day, petiole length growth rate was 29% per day, the stem diameter growth rate is 4% per day, and the wet weight growth rate is 1.42% per day.
