What the LED Grow Light wavelength you use?

  • Blue (wavelength: 440nm, 460nm): Help plants grow. 
  • Red (wavelength: 630nm, 660nm): Help plants grow and flowering,  red LED is the key for flowering plants. 
  • IR (wavelength: 730nm,740nm): IR can help plants grow, but it very harmful human beings, so I kindly suggest you do not use IR in your grow lights, but we can add 1 or 2 piece IR LEDs if you really need it in a specific situation. 
  • UV (wavelength: 380nm): UV can help plants grow and kill insects, but it also very harmful for human beings, so we do not add it so many in our led grow lights.
