Plants need light to grow and develop properly. Different types of light, like red and blue, affect how plants use nitrogen for growth. Light influences the genes that help plants take up and use nitrogen, especially during the early stages of growth. As plants mature, the length of daylight and internal rhythms also play a role in their development. The amount of nitrogen available can affect when plants flower or go dormant. Overall, light has a big impact on how plants use nitrogen for growth and development.
