The 450nm spectrum enables cryptochromes and phototropins to mediate plant responses such as phototropic curvature, inhibition of elongation growth, chloroplast movement, stomatal opening and seedling growth regulation. It affects chlorophyll formation, photosynthesis processes, and through the cryptochrome and phytochrome system, raises the photomorphogenetic response.
These wavelengths encourage vegetative growth through strong root growth and intense photosynthesis and are often used as supplemental light for seedlings and young plants during the vegetative stage of their growth cycle, especially when “stretching” must be reduced or eliminated.
The 624nm region has the highest photosynthetic relative quantum yield for a range of plants. At the same time, its action on red-absorbing phytochrome is considerably weaker compared to that of 660 nm red light and can be used to balance the phytochrome equilibrium towards lower values (closer to those of daylight) than those achievable with 660 nm red light.
The 660nm wavelength has a very strong photosynthetic action and also exhibits the highest action on red-absorbing phytochrome regulated germination, flowering and other processes. Most effective for light cycle extension or night interruption to induce flowering of long-day plants or to prevent flowering of short-day plants. Most energy-efficient source for photosynthesis among all available supplemental LEDs. - See more at: http://www.illumitex.com/impacts-colored-light-plants/#sthash.aJqG1cpP.dpuf
