Abstract

The purpose of this project is to determine the effect different colored wavelengths have on Wisconsin Fast Plant growth. In this project, 18 wisconsin fast plants were grown underneath four different colored wavelengths. The wavelengths tested were blue light (475 nm), green light (510 nm), red light (650 nm), and white light (400-700 nm). The plants were tested and measured until the end of their life cycle, four weeks later. In the first two weeks of the plant's life the green plants were significantly behind the other plants, they were averaging about 3 or 4 inches, while most of the plants were 6 to 7 inches. The blue plants had an average of 7.0 inches and the white plants were averaging 6.5 inches, the red plants averaging about 5.8 inches. Two weeks later the green plants measured about 5 inches. The blue plants were still about 7.0 inches and the red plants were about 7.0 inches. The white plants, were the only ones that ended up reaching 10-12 inches and they were also the only plants that flowered. In conclusion, plants grown with all wavelengths of light will show more growth than plants only using one wavelength.
