Effects of different light wavelengths on the growth of water spinach (Ipomoea Aquatica)

This study explores the effect of different LED light wavelengths on the growth of water spinach (Ipomoea aquatica). Over an eight-day period, plants were exposed to red, blue, white, and green LEDs, and their height and leaf development were monitored. Red light produced the greatest height increase (4.7 cm), while blue and white lights supported balanced leaf growth, with three leaves each by Day 8. Green light resulted in the least growth. These results highlight the importance of light spectrum in shaping plant growth and suggest practical applications for optimizing sustainable indoor agriculture.
