Spectrum Comparisons and Photon Efficacy for Cannabis

Spectrum Comparisons and Photon Efficacy for Cannabis Professor DeBacco Reference Article Kusuma, P., Pattison, P.M. & Bugbee, B. From physics to fixtures to food: current and potential LED efficacy.

Photon Efficacy Note: Photon Efficacy of HPS lights = ~1.7 Compare that to the Red LED chips which are 2.6 times the efficiency *The conversion of efficiency to photon efficacy depends on spectral distribution. Plant Action Spectra Light Pollution on Soybean Crop Metal Halide to HPS “Flip” for Cannabis MH in veg @ 18hr. HPS in flower @ 12hr MH has 30% blue to keep plants short (tight internodes) HPS only 4% blue, but efficient light Green photos important for visual disease diagnosis Sunlight has ~30% blue DLC (Design Light Consortium) for Light Efficiency Independent company that list many lights from different manufactures and publishes test results for the efficiencies of the lights 2.5+ umol/Joule is very efficient Special Thanks To… Combination of research data from… Dr. Bruce Bugbee of Utah State University and Founder of Apogee Instruments Inc.
