A common question asked among growers is: how does different color light affect plant growth? The answer is yes! The color of light sure has an effect on plants’ growth and we will be discussing why this is so.
Light is one crucial factor required for the optimal growth of plants. They are important for the reaction and activities that go on in your plants which are required for proper development. The color of light affects the growth of plants in many ways and we will be discussing deeper this.
How Does The Color Of Light Affect Plant Growth
The light that your grow light emits comes in a different spectrum for the use of your plants’ growth. The color of grow light you supply your plant will not only have an effect on your plant, but it will also determine the result of your plants’ development.
The process of photosynthesis where plants make their food requires the use of light. Also, chlorophyll is responsible for the green pigmentation of leaves and stems. Chlorophyll requires light to transform carbon dioxide into food and this is done by the energy from light.
Some Important Color Of Light Used By Plants
Blue, red, green, yellow, and a couple of other light colors are essential in the plants’ life cycle. Let’s take a look at some of this color of light and see how they affect the growth of your plant:
Blue light has a short wavelength and high energy in the color spectrum which makes them easy to absorb by plants. They are very important for the early plant stage such as seedlings and some seeds may not germinate if this blue light is absent. This is the light to be used when your plants are beginning to sprout.
Blue light is easily assimilated by plants which they convert to energy to attain maturity faster. A blue light will also enhance the quantity of chlorophyll that is produced by your plant.
Red light has a long wavelength therefore their energy level is not so great for plants. Now, red light is usually very effective on plants when combined with other light colors such as blue light. The combination is ideal for matured plants such as the flowering phase.
Red & Blue Light Combination
The red and blue light are a great combination and they are needed as your plant matures. They are especially required for both the vegetative and flowering stages. This red and blue light enhances the production of more leaves and crops.
Violet Or Purple Light
Violet light or purple light is an additional light that your plant will benefit from. These colors have the shortest wavelength and high energy which enables the plant to be able to absorb them well. The light energy in violet color results in sweet aroma, great plant color, flavor booster in vegetables and fruits.
Therefore, you can use this light at any stage of a plant to boost the color and improve your plants’ taste. Violet light will also enhance the number of antioxidants accommodated in a plant.
The effect of green light on plant growth is not so much. The reason being that most plants are already green in color thus will reflect green rather than absorb them.
Yellow light does not have much effect on the growth of a plant. They are just like green lights which are difficult for plants to absorb.
Ultraviolet light is known to be harmful to humans. So, just as ultraviolet light is harmful to humans, high exposure is also bad for plants. Your plants will develop with little exposure to ultraviolet light.
Best Color For Plants That Will Affect Their Growth
Having mentioned most of the colors your grow light will produce; now we are wondering what the best color that will affect the growth of plants?
The best and most important colors for the development of your plant are the red and blue light colors. Blue light is ideal for the early plant stage such as seedlings. As your plant matures, the red and blue light colors are combinations excellent for your plants’ growth.
Does The Color Of Light Effect Plant Growth Final Say
The colors of light contribute a lot during different growth stages in a plant’s life cycle. Light colors will also increase help the yield of your crop production in many ways. Matter of fact, the absence of light means the absence of vegetative or floral plants.
Therefore, we have concluded that the color of light does affect plant growth.
