LED Grow Lights are now competitive with and at times outperform older HID technology. The best LED grow lights that give the highest yield per watt will have the most favorable spectrum for plant photosynthesis. LED lights that have 7-8 wavelengths of light along with UV and infrared will give the highest yields and the healthiest, highest quality plant production. It takes 7-8 wavelengths to replicate the photosynthetic action radiation provided by the sun for plant photosynthesis and this is the ideal blend for the highest yielding LED grow lights.
Lights that have less than 7 wavelengths will be missing some critical spectra and will not provide the same high quality of growth as lights with the ideal spectra. Conversely, led lights with more than 8 bands are providing excess wavelengths, which do little or nothing to enhance plant quality and yield and can actually reduce plant growth and resin production. If more wavelengths were better when it comes to plant production, we would want the LED grow light to encompass all the wavelengths of light. This is not the case, so the excess wavelengths make the lights less efficient. The result is a lower yield per watt when there are too many wavelengths.
The highest yielding LED Grow Lights have the... Continue story HERE
