Full Spectrum 200w Led Grow Light

How do led grow lights promote plants growth?
Different wavelengths of light have different effects on plant growth. For example, blue light promotes leaf and stem growth, while red light promotes flowering and fruiting. Therefore, plant grow lights are designed to emit specific wavelengths of light to meet the different needs of plants at different stages of growth.

In addition to the growth spectrum, light intensity is also important for plant growth. Plants need a certain amount of light energy to perform photosynthesis effectively. Too little light can result in weak and spindly growth, while too much light can damage the plant.

Plant grow lights come in several types, including fluorescent, LED, and high-intensity discharge (HID). LED grow lights are becoming increasingly popular due to their energy efficiency and the ability to customize the light spectrum for specific plant needs.

When using plant grow lights, it is important to consider the duration and intensity of light exposure. Most plants require approximately 12-16 hours of light per day for optimal growth. It is also important to provide a dark period for plants to rest and perform other metabolic processes.

Overall, with the advancement of technology, indoor plants or plants in areas with limited natural light can thrive with the help of plant grow lights. These lights provide the spectrum and intensity of light necessary for plants to photosynthesize and grow healthily.



This is a color spectrogram, where scientists use wavelength numbers instead of color names to represent colors, which is a more accurate way to measure color. Different wavelength frequencies represent different colors of light.

This method of measuring plant growth light is called PAR (photosynthetically active radiation). PAR defines the relative number of light plants used for photosynthesis in the 400 nm to 700 nm range.

Generally, the peak of photosynthetic efficiency (light absorption) falls in the red and blue light spectrum in the PAR range. This means that plants absorb the most of these spectra during growth. In other words, chlorophyll, the molecule responsible for converting light energy into chemical energy in plants, absorbs most of the light in the blue and red spectra for photosynthesis.

So by choosing the right amount of red and blue light, chlorophyll pigments can absorb more of the light they need.

For growth, in the early vegetative growth stage, blue light helps plants produce healthy stems and roots. Then it continues to grow as the absorption of red light increases, resulting in longer stems, increased leaves and flowers/ fruits. So red light plays an important role in plant maturity and its size.

Since blue and red light can best promote photosynthesis, should we care about other wavelengths? Absolutely yes, research results show that plants grow best when they receive all the colors of the visible spectrum. That is, broad-spectrum grow light，we usually called full-spectrum grow light, which refers to the complete spectrum provided by sunlight.

The LED plant growth light can be set to produce a specific wavelength during a specific time period during the day or night.

Full-spectrum grow light can not only speed up the growth of plants, but also slow down the growth of plants. If you don't need it to be so lush, you can also adjust the light as you needed.

In conclusion, LED plant growth lights play a very important role in promoting root development, improving nutrition and color.
