"True Infrared" Supplemental strips have finally arrived! The PAR or Photosynthetically Active Radiation range measures light intensity and output in the spectral range from 400nm - 700nm. Traditional thinking is that light outside of this region plays little role in chlorophyll production and photosynthesis since the photosynthetic efficiency of monochromatic Far Red light sharply declines with the increase in wavelength. However, as early as 1957 Robert Emerson (Emerson Effect) was doing pioneering research that showed when plants are exposed ONLY to wavelengths above 680nm or ONLY to wavelengths below 680nm the rates of photosynthesis was fairly low, but when plants were exposed to both rates above AND below 680nm the rate of photosynthesis increased significantly. His conclusion was there must be two photosystems at work in the plant, one driven by shorter and one driven by longer wavelengths of light.    Furthermore, recent studies have shown that  As such there has been less rese
