Can Colored Lights Affect the Plants Grow by led grow light kits?
Plants respond differently to lights of different colors, and the led grow light kits can meet affect plants grow.
Most people know that the main energy produced by plants is light. This process of converting light into objects is called photosynthesis. However, it may be news to you that the color of light has a measurable effect on the energy absorbed by plants.
The reason is that the light color have different wavelengths, and these wavelengths provide different energy levels depending on whether they are short or long.
The highest energy light is at the purple or violet end of the color spectrum. Violet and violet light have very short wavelengths, so they have a lot of energy. At the other end of the spectrum, you will find red light with a longer wavelength and lower energy.
Regardless of whether the light color is red or purple, the plant will absorb a certain amount of energy from the light. Green light has the worst effect on plants because they are inherently green due to chlorophyll.
Different colors of light also help plants achieve different goals. For example, blue light helps promote the growth of vegetative leaves. The combination of red light and blue light can make plants bloom. Cold fluorescent lamps are very suitable for growing plants indoors.
In a world that relies on plants for food, it is important to understand that different colors of light affect plant behavior. Advanced LED technology can now control the types of colored light we provide to plants in a controlled environment.
For example, we can now design lighting to promote flowering or produce higher fruit yields. Many plant functions can be enhanced and promoted by understanding what light color they respond and respond to.
This is crucial for a hungry world that has just realized the effects of global warming. It will enable us to provide environmentally friendly alternatives to help improve crop quality and growth without having to resort to strong fertilizers and genetically modified foods.
Plants need sunlight to grow more luxuriantly
The effect of light on plant growth is to promote plant chlorophyll to absorb nutrients such as carbon dioxide and water to synthesize carbohydrates. But modern science can make plants grow better in places where there is no sun.
People have mastered the inner principle that plants need for the sun, which is the photosynthesis of leaves.
The photosynthesis of leaves requires the excitation of external photons to complete the entire photosynthetic process.
The sun’s rays are a process of energy supply stimulated by photons. Artificially created light sources can also allow plants to complete the photosynthetic process.
Modern horticulture or plant factories are combined with supplementary light technology or complete artificial light technology.
Scientists found that the blue light zone and the red light zone are very close to the efficiency curve of plant photosynthesis and are the best light sources for plant growth.
At present, there are mainly the following kinds of light involved in the plant lights on the market: red light, blue light, white light, warm white light, purple light, etc.
1. Different wavelengths of light have different effects on plant photosynthesis. The light required for plant photosynthesis has a wavelength of about 400-700nm. 400-500nm (blue) light and 610-720nm (red) contribute the most to photosynthesis.
2. Blue (470nm) and red (630nm) LEDs can just provide the light needed by plants. Therefore, the ideal choice for LED plant lights is to use these two color combinations. In terms of visual effects, the red and blue plant lights are pink.
3. Blue light can promote the growth of green leaves; red light is helpful for flowering and fruiting and prolonging the flowering period.
4. The ratio of red and blue LEDs of LED plant lights is generally between 4:1–9:1, usually 4-7:1.
5. When plant lights are used to supplement light for plants, the height from the leaves is generally about 0.5 meters, and continuous exposure for 12-16 hours a day can completely replace the sun.
Use LED semiconductor lights to configure the most suitable light source for plant growth
Proportional colored lights can make strawberries and tomatoes sweeter and more nutritious.
To illuminate holly seedlings with light is to imitate the photosynthesis of plants outdoors.
Photosynthesis refers to the process by which green plants use light energy through chloroplasts to convert carbon dioxide and water into energy-storing organic matter and release oxygen.
Sunlight is composed of different colors of light, and different colors of light can have different effects on plant growth.
The LED light source is also called a semiconductor light source.
This light source has a relatively narrow wavelength and can control the color of the light. Using it to irradiate plants alone can improve plant varieties.
The holly seedlings tested under purple light have the highest growth, but the leaves are small, the roots are shallow, and they look like malnutrition. The seedlings under the yellowish light are not only short, but the leaves look lifeless.
The holly that grows under the mixed red and blue light grows best, not only is strong, but the root system is also very developed. The red bulb and blue bulb of this LED light source are configured in a ratio of 9:1.
The results show that the 9:1 red and blue light is the most beneficial to plant growth.
After this light source is irradiate, strawberries and tomatoes are full, and the content of sugar and vitamin C is significantly increased, and there is no hollow phenomenon.
Continuous irradiation for 12-16 hours a day, strawberries and tomatoes grown under such a light source will be more delicious than ordinary greenhouse fruits.
What make a good led grow light kits?
1. Good lamp bead ratio
For all types of cannabis plants, full-spectrum and red-spectrum LED plant lights are good choices.
Color temperature refers to the color of the emitted light. Our LED grow lights use international brand Samsung SMD chips. The lamp beads of this LED plant growth lamp are adapt of full-spectrum three-star white light (3000K+5000K) and 660nm red light, which can help plants from seedling to harvest. For ordinary plantings, LED grow light kits can better save more cost and yield for growers.
During plant growth, cannabis grows best when it provides approximately 5,000 Kelvins of cool sunlight blue light.
Under the growing situation, the warm white color 3000K can works best during the flowering stage.
2. What are PPFD and PPE?
In rainy or cloudy days, LED grow light kits can replace natural sunlight and provide power for the growth of cannabis plants and their buds. Light is very important for the production of plants. “If there is not enough strong light, even healthy cannabis plants will not produce too many buds. As an alternative to HPS grow lights, this LED grow light is very popular with cannabis growers.
What is meaning of PPFD? PPFD is the photosynthetic photon flux density. When choosing led plant lights, you should compare the PPFD values of different plant lights.The luminous flux value is bigger, the plant effect is greater.
What is meaning of PPE? PPE refers to photosynthetic photon efficacy. PPE describes the amount of light produced by the growth lamp from its input power. The metric used to measure PPE is micromoles per watt per second-since watts are joules per second, it is simplified to µmol/J.
3. What power is available for grow led lights?
Because the actual power of the plant light always changes with different conditions, all sellers use the rated power to describe the power of the product, because the rated power is constant. When you choose LED grow lights, the rated power of the grow lights is a reference. We have 400 watts, 600 watts, 800 watts, 1000 watts, 1200 watts, 1500 watts available to choose. You can choose different wattage plant lights according to the size of your planting places. We can also provide advice of installation hieght and the qty you need according to your requirements.
4. Where are the led grow light fixture can install?
This LED plant growth light is specifically designed to replace natural light, stimulate photosynthesis, and provide a suitable color spectrum to enable plants to grow and prosper. It is an energy-saving lamp used by indoor and greenhouse farmers and cannabis growers.
It can be widely install at greenhouses, farms, container farms, hydroponics, vertical farms and mini gardens so on.
