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.…

Measuring Photosynthesis & Consumer Interpretation: PAR, Lumens, PPFD & DLI

Words and images by @SuperFunker. Part 1: PAR Photosynthesis is the photochemical process by which plants and other organisms use light to synthesize sugars from carbon dioxide and water. The spectral range of light that induces photosynthesis is called Photosynthetically Active Radiation (PAR). PAR is defined as visible light that…
