Here is how specific wavelength works: 
Blue (wavelength: 450nm): Helps plants leaf grow.
Red (wavelength: 660nm): Helps plants flower and grow.
Red LED is the key for flowering plants, more suitable for the vegetative stage and blooming stage of any plant. Sources rich in red light are more efficient and beneficial for photosynthesis, best for blooming and fruit. The Chlorophyll and Carotenoid need blue much, good for the photosynthesis, best for promoting the leaf.
