There be Light How Wavelength Composition, Intensity and Duration Affect Plants by Dr. J. Benton Jones, Jr.

There are three characteristics of light—be it natural or artificial—that impact plants: wavelength (spectral) composition, intensity and duration. Dr. J. Benton Jones, Jr. shares some of his personal experiences with the high and filtered light energy effects on plant response and growth…

For several years, a colleague and I conducted a series of greenhouse tomato experiments in order to evaluate cultivar performance, and the effects of rooting media, plant population and topping on plant growth and fruit yield. These experiments were conducted in two greenhouses located just a few miles from each other, yet if you went from one greenhouse to the other, you would think that the experiments were entirely different due to the plants’ appearances. The tomato plants in the glass-covered
