In order to effectively mix spectrums between light sources, their individual intensities must be well matched. For example, there’s precious little benefit in hanging a 315W CMH at the same height as a 1000W DE-HPS greenhouse style fixture, as the blue-rich light of the CMH will end up being “drowned out” by the 1000W DE-HPS, especially when both fixtures are positioned several feet or more above the canopy.
Only by combining the blue-rich spectrum of the Hellion DE-CMH and the orange / red-rich spectrum of the Hellion DE-HPS at close proximity can growers realize the true benefits of spectral mixing. When these all-important colors are blended at useful and comparable intensities growers can achieve the mythical “Emerson Effect” where photosynthetic rates appear to go into overdrive.
