There are many people who are just starting to grow plants or vegetables for a hobby and often wonder how the tree can grow in the best condition. And “Does the color of light affect plant growth”? is one of the most popular questions people usually ask.
There are many types of light that support the growth of plants, however, there are some other lights that can damage plants, typically ultraviolet light. To better understand each kind of light as well as its function, let’s scroll down for more!
The Color Of light Creates Effect On Plant
Things You Need To Know About Visible Light
One of the electromagnetic radiations you should know is visible light. In fact, visible light can be described as the wavelengths moving through space. And of course, the human eye can see visible light.
Electromagnetic radiation is sent in waves or particles of the different frequencies and wavelengths. The distance of the wavelength is called the electromagnetic spectrum. Probably you have already known, there are 7 types of the electromagnetic spectrum which are isolated in declining order of wavelength and vitality. They are:
- The Radio-waves
- The Micro-waves
- The Infrared
- The Visible-light
- The UV-beams
- The X-rays
- The Gamma-rays
Does The Color Of Light Affect Plant Growth?
To answer the question: “Does the color of light affect plant growth?”, we explain to you the way that each color light impacts plants. There are 6 main lights in nature. Let’s see!
Ultraviolet light is commonly known as UV light, which is very harmful to human health, especially the skin. At the point when an individual is exposed to an excessive amount of UV beams, they can get burned from the sun and suffer from the negative impacts of UV light.
Same as humans, ultraviolet rays are also harmful to plant growth. So to help your plants grow better, you should prevent them from UV exposure.
While ultraviolet light is harmful to plants, violet light is great for plant growth. Violet light brings positive energy to plants, so the color of fruits and vegetables is also enhanced. As a result, the tree smells better and is increased in antioxidants by absorbing purple light. It can be said that violet light is one of the lights that plays an important role in the life of the tree. And of course, it also has the ability to protect the tree from damage.
Blue light has a great influence on young plants that are in the early stages of development. This type of light helps the plant produce more chlorophyll, the higher the green pigment, the better the plant grows. In other words, blue light allows plants to absorb light and photosynthesis more easily. As a result, the tree grows quickly and increases its maturity. Plus, blue light exposure enables the seed to grow and guarantees the development of roots, stems, and leaves later on.
Do you realize why plants can absorb a wide range of light but only reflect green light? That is because the leaves of plants are usually green. The green light works to help the greener plants by increasing chlorophyll production. Because of this, many merchants use green light in greenhouses to make trees look greener and fresher, attracting customers’ attention when shopping for trees.
Like green light, yellow light plays an essential role in plant growth and health. However, one main difference between the two types of light is that yellow light does not directly help the plant produce chlorophyll. Some research also suggests that to help plants stay healthy in a greenhouse environment, the yellow light should be removed immediately.
Red light does not seem to carry as much energy as other colors. However, in return, the combination of red light and blue light is very effective for mature plants. This type of light helps the flower to bloom and moreover, the amount of leaves on the tree also increases.
How Color Corresponds To The Life Of The Plant
Typically, a tree grows in 4 stages: germination, maturation, flowering, and fruit harvest. For plants that are in the early stage – sprouting – you should use blue light. It helps increase the chlorophyll in plants. Next, in the two stages of maturity and flowering, red and blue light are combined to encourage the production of leaves.
On the other hand, purple light can enhance the color and smell of the tree and is used for any type of plants at any time of growth. So after all, we hope you have found the answer to the question: “Does the color of light affect plant growth?”
How color corresponds to the life of the plant
How to choose the right light
You may wonder why many plants come from the same seed but produce different results. That may be partly due to the light provided to the tree. Typically, plants need to be given full-color light. However, if the tree receives a lot of red and blue light, the function of the plant will improve better. On the contrary, if the tree absorbs yellow and green light more, the tree will be more beautiful and greener in appearance.
Recommended grow lights
For tree enthusiasts, this section can be very helpful. Here are suggestions for the types of lights that help your plant grow in the best grow box for beginner.
- High-intensity discharge light: used for growth and development stages. These lights require more electricity and therefore, produce more heat for the plants.
- Fluorescent light: this type of light is specially made of blue light. Typically, fluorescent lighting does not provide the full range of colors, but it is still effective for some plants, such as herbs or lettuce.
- LED lights: This kind of light is created by red light and blue light, which is suitable for the greenhouse environment.
- Incandescent lights: in contrast to LEDs, incandescent light is not a good idea to put in a greenhouse. For decorative and aesthetic plants, growers often use incandescent lights. They are usually cheaper than other lights, however, they only function to beautify the tree, not providing the full intensity that the tree needs.
Does the color of light affect plant growth? Of course, yes! Each type of light, each color of light will have its own characteristics. And from there, it influences and supports growing trees in different ways.
Hopefully, through this article, you and other plant lovers can better understand how to take care of your tree and help it live longer. Good luck!
