The most important function for our purposes is that blue light suppresses extension growth. This results in shorter plants with thicker, bushier leaf growth. Without blue light, plants will stretch and grow spindly and weak.
Keeping this in consideration, why is blue light best for plant growth?
Blue light produces more lush greenery. Blue light is necessary for plants to regulate plant growth, as it helps to create strong stems and also helps create the chlorophyll necessary for plant processes. … In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light.
Regarding this, is blue light better for seedlings?
Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly). Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).
Do blue lights help plants grow?
The effect of blue light on plants is directly related to chlorophyll production. Plants that receive plenty of blue light will have strong, healthy stems and leaves. Red light is responsible for making plants flower and produce fruit.
Generally, only a low intensity of blue is needed in a light spectrum for fully functional photosynthesis. … Generally, blue light suppresses extension growth; plants grown with blue light are usually shorter and have smaller, thicker and darker green leaves compared to plants grown without blue light (Figure 1).
