450 nm BLUE
This light enacts regulation by cryptochromes and phototropins, mediating various plant
responses, such as phototropic curvature, inhibition of elongation growth, chloroplast
movement, stomatal opening and seedling growth regulation. Can be directly absorbed
by chlorophyll in photosynthesis. Recommended as supplemental light for seedlings and
young plants during the vegetative stage of their growth
cycle, especially when “stretching” must be reduced or eliminated.
