Importance of Spectrum: Indoor Cannabis Sea of Green Cultivation
Original Research by SGS through Research Team member Haley Bishoff
Smart Grow Technologies is proud to announce our newest white paper launch. This research contains the most current scientific information on the importance of spectrum when using the Sea of Green (SOG) method from beginning to end, clone to harvest.
The importance of cultivating indoor cannabis using full-spectrum LED lights that mimic the sun’s quantum response area of the visible light spectrum. Photosynthetic Photon Flux Density(PPFD), carbon dioxide (CO2) and temperature levels are the main variables that contribute to the rate of photosynthesis. Plants react to a range of photonic energy, between 400-700 anometers (nm). When cultivating indoor cannabis, there are two main phases: propagation and flowering. Both phases require full spectrum, while propagation needs higher blue light and flowering needs higher levels of orange and red light. Green light helps drive photosynthesis, specifically in the lower leaves of plants. The Sea of Green method focuses on growing a larger quantity of smaller plants, while traditional growers cultivate a small number of large plants.
Smart Grow Systems provides highly engineered LED, full spectrum lights for the propagation and flowering phases of the grow cycle. For standard size cannabis plants, 1,500 μmol m-2 s-1 PPFD at 25-30 C has shown to contribute to an optimal rate of photosynthesis during the last few weeks of the flower cycle. For Sea of Green, indoor growing conditions of 1,100 μmol mm-2 s-1 PPFD at 25-26 C exhibit the highest rate of photosynthesis during the last few weeks of the flower cycle.
