LED colors are important because they have different functions for the growth of your plants:
Blue: provides more energy to plants through chlorophyll synthesis, to stimulate germination.
Red: contributes to efficient germination and flowering, and stimulates photosynthesis.
Blue and red combination: both colors contribute to optimal growth and complete impacts on the plants.
It is also important to know that there are many grow lights labeled as ‘full-spectrum’. This simply means that they emit light across a full-color spectrum, including colors other than blue and red.
