Experiment_100:
For this experiment we wanted to test whether the colorful grow light (instead of the simple Sodium-Vapor Lamps-HPS lamps) can be transmitted to the bowl via fiberoptics. According to wikipedia regarding Grow Light: Red spectrum light may trigger a greater flowering response in plants. If high pressure sodium lights are used for the vegetative phase, plants grow slightly more quickly, but will have longer internodes, and may be longer overall" and "Blue spectrum light may trigger a greater vegetative response in plants". Also, "Different stages of plant growth require different spectra. The initial vegetative stage requires blue spectrum of light, whereas the later "flowering" stage is usually done with red–orange spectra." In the experiment we worked with scallions' rhizhoma that can grow with the method of hydroponics.
Items used in this experiment: fiberoptics, multi-color grow light, rhizhoma, water, MassArt "eye-bowl" container.
