This grow light spectrum chart illustrates how PAR coincides with visible light spectrum. How Do Plants Respond to Light? Plants use light for photosynthesisand photomorphogenesis. Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy. ...
Indoor plant grow lights provide a similar light spectrum to the sun by varying the colour, intensity (called lumens) and temperature of the light output. Countless studies show different types of plants respond better to different colours and intensities of light, so using indoor grow equipment ...
