Far Red LED Grow Lights
Most LED grow lights utilize red LED grow lights and blue LEDs, with their peak wavelengths optimized for plant photosynthesis. The peak wavelength for blue is around 450 nm, while red LED grow lights peak at about 660 nm, aligning with chlorophyll A and B absorption. Additionally, far red LED light extends the spectrum, offering wavelengths beyond 660 nm to further support plant growth.
