First, let’s talk about the role of blue light. Blue light, with wavelengths between 400 and 500 nanometers, especially the 450nm,is essential during the early stages of plant growth. This LED wavelength promotes vegetative growth, including the development of strong stems and leaves. For example, if you're growing leafy greens like lettuce or spinach, blue light helps these plants develop robust foliage. Blue light also plays a significant role in photomorphogenesis, which is the process that controls the development of a plant's structure and form, such as the opening of stomata, which are vital for gas exchange and water regulation.
Red Light 660nm
Next, we have red light, with wavelengths between 600 and 700 nanometers. Especially the 660nm. Red light is crucial during the flowering and fruiting stages of a plant’s life cycle. For instance, if you're growing tomatoes or strawberries indoors, red light and also 730nm infrared light can accelerate the flowering process and increase the yield of fruits. Red light is also highly efficient for photosynthesis, helping plants convert light energy into chemical energy more effectively.
