Why is red light good for plants?
Just so, how does red light affect plant growth?
Red Light and Vegetative Growth. Red light fits with the absorption peak of chlorophylls, which do photosynthesis to produce sugars and carbons1. Sugars and carbons are essential for plant growth, as they are the building blocks for plant cells. For this reason, red light increases photosynthesis rate and plant size2.
Beside above, is red or blue light better for plants? The color of light does indeed affect plant growth, but the effect is more noticeable under low light intensity. Red and blue light are most effective for plant growth, while green has minimal effect. UV light can damage plants, causing leaves to burn.
In this regard, why do plants absorb red light the best?
Trees and plants are green because of a green pigment called chlorophyll. This pigment absorbs red light the best, and converts the light into energy that it uses for metabolism. As you likely know, this pigment allows plants to use light as a form of energy, as a part of a process called photosynthesis.
Is infrared light good for plants?
In addition, exposure to infrared light reduces the time a plant needs to flower." Note that your plants only grow well under appropriate amount of infrared light. Otherwise, too much infrared light will interrupt normal blooming cycle and even kill them because of extra radiation, namely heat.
