Description:

Blue light influences the formation of chlorophyll, enabling the plant to intake more energy. Plants that receive plenty of blue light grow with strong, healthy stems and leaves. This process is called photomorphogenesis.
Red light contributes to the optimal development. It’s essential to a plant’s early life for germination, root growth, and bulb development. It also makes the plant yield better results when flowering.
