Read MoreLight Quality in Cannabis Cultivation by Ed Rosenthal
The quality of light is its color, or spectrum. Light spectrum is useful for directing the plant’s growth habits, as well as contributing to healthy photosynthesis. Comparing this to a car, if light intensity is the gas pedal to increase speed of photosynthesis, light quality would be the steering wheel. Using different colors of light allows growers to affect the plant in terms of yield, flavor, color, growth, flowering, and even the severity of pests and diseases (Davis and Burns 2016).
