Abstract

Artificial lighting, including high-pressure sodium lamps, fluorescent lamps, and light-emitting diodes (LEDs), has been used to aid in the growth of many plants. However, there is still limited knowledge as to the effects of red, blue, and green LED lights on the growth of Abelmoschus esculentus var. smooth green. Thus, the effects of LEDs as an artificial light source on the plant height and root length of Abelmoschus esculentus var. smooth green have been examined in this study. Seedlings that were germinated for 14 days were tested in four separate setups: three treatments and one control. Results showed that at the end of the 14-day LED light treatment from 6:00 AM to 6:00 PM, the plant mortality percentage was 100% in all treatment groups. As a result of the limited amount of data gathered, the researchers were unable to conduct data analysis.
