Abstract—Electric currents have been utilised to stimulate growth within plants to a great extent. This technique, known as electroculture, often involves action potentials on soil-based plant systems. Studies that investigate this phenomenon are plenty, however minimal research has been done to investigate electroculture on a hydroponic based system. Furthermore, a constant application of electricity on hydroponics has not been tested before. In this paper, we explore the relationship between the growth of a Vigna Radiata species and the constant application of electricity (5 minutes, 10 minutes, 15 minutes) under a hydroponic based system. To monitor the development of the species, we employed three main growth parameters: Visibility of germination, circumference of stem, and length of shoot system. Daily growth rates were computed using the lengths of the shoot system of a single day and the day before. Results indicate an inversely proportional relationship between direct current application and growth. During primary stages of the experiment, group 5 and group 10 species experienced the highest peak growth rates at values of 139.13% and 113.79% respectively, followed by a sharp decline in subsequent days. Alongside, the control group had a peak growth rate of 64.17% with a gradual decline. However, the group 15 species presented a mortality rate of 100% and measurements were unable to be obtained, due to a lack of germination. Overtime, species receiving less exposure to electricity showed longer lengths of the shoot system near the end of the experiment. Based on the results presented, hydroponic electroculture systems have shown to experience peak growth rates near earlier stages of their development. This however, fails to hold after a certain limit, in which plants fail to germinate due to excessive exposure to electricity. Further research conducted in this field may possibly encourage the usage of electroculture systems in agriculture.
