Maximize Cannabis Growth @ 700, 1,500 or 2,000 µmol/m2/s? And, What About CO2?
Words and images by @SuperFunker. How 'high' must Photosynthetic Photon Flux Density (PPFD, µmol/m2/s) be to induce peak photosynthesis in Cannabis? In 2008, Chandra measured a maximum rate of photosynthesis at 1,500 µmol/m2/s. In 2015, Chandra conducted a similar assessment and measured a maximum rate of photosynthesis at 2,000 µmol/m2/s. So, problem solved... right? Not necessarily. Chandra, 2008. Chandra's 2008 Cannabis analysis is a two part study. First, he measured the photosynthetic response to a range of light intensities at various temperatures. The light and temperature combination that produced peak photosynthesis was then applied to a series designed to gauge...
