They are very important for the early plant stage such as seedlings and some seeds may not germinate if this blue light is absent. This is the light to be used when your plants are beginning to sprout.

Blue light is easily assimilated by plants which they convert to energy to attain maturity faster. A blue light will also enhance the quantity of chlorophyll that is produced by your plant.

Red Light

Red light has a long wavelength therefore their energy level is not so great for plants. Now, red light is usually very effective on plants when combined with other light colors such as blue light. The combination is ideal for matured plants such as the flowering phase.
