With LED grow lights lies a remarkable scientific principle: plants' ability to convert light energy into chemical energy through photosynthesis. LED lights mimic the natural sunlight required for photosynthesis but with a key advantage – they emit light in specific wavelengths that cater to the unique needs of plants. LED grow lights are designed to provide light in the blue (400-500nm) and red (610-720nm) ranges, which are crucial for plant growth. While traditional lighting sources emit a broader spectrum of light, often wasting energy on wavelengths that plants don't utilize, LEDs are highly efficient. This targeted approach allows plants to thrive while using less energy, a significant benefit for both the environment and your energy bills.Understanding the Science Behind LED Light Wavelengths
The science of LED grow lights extends to the concept of light wavelengths. Instead of naming colors, scientists use wavelength numbers, offering a more precise measure of light. For instance, a red LED light might have a wavelength of 630 or 660. To our eyes, both appear red, but they are distinct wavelengths. Plants absorb light primarily for photosynthesis through chlorophyll, including Chlorophyll A and B. A look at the absorbance spectrum reveals peaks in the blue and red regions, indicating that these colors are crucial for photosynthesis. Surprisingly, little light is absorbed in the green range, leading to the misconception that plants only require blue and red light.Blue and Red Lighting
While blue and red light are essential for plant growth, it is incorrect to assume that plants grow alone with these colors. A comprehensive study of light absorbed by an entire leaf reveals that plants utilize a broader spectrum, including green and yellow light. Research by NASA has further proven the impact of specific wavelengths:- Red Light (630 - 660 nm): Essential for stem growth, leaf expansion, flowering regulation, dormancy periods, and seed germination.
- Blue Light (400 - 520 nm): Influences chlorophyll content, and leaf thickness, and requires careful management to avoid stunting certain plant species.
- Green Light (500 - 600 nm): Penetrates dense canopies to support lower canopy leaves.
- Far Red Light (720 - 740 nm): Passes through upper canopies, supports lower leaf growth, reduces flowering time, and encourages larger leaves.
