How to Choose The Best LED Light Recipes For Your Plants


The perfect LED light recipe for your plants depends on the type of plant you are growing as well as its life cycle stage.

When it comes to choosing lighting for your indoor grow space, the light you see is not necessarily what your plants need. While some of the light needed by plants falls in the visible spectrum, they also required wavelengths we are unable to see which is UV and Infrared wavelengths. Fortunately, through extensive testing and studying different wavelengths to determine the perfect ratio of colors of light needed by different types of plants, we have perfected the ratio needed across the board for all types of plant growth.

The Effects of LED Light Recipes On Plants

Plant growth, quality, and yields are dependent on the different wavelengths of light they receive.

Recent research indicates that optimal LED light recipes offer the following benefits:

  • Increase plant production by 29.72 percent
  • Crops are ready to harvest earlier than with non-LED lights
  • LED light recipes containing 16 percent blue light produce the most biomass
  • LED emitting blue and red light tend to produce larger plants with bigger leaves than other types of light

Selecting The Best Types Of LED Lights 

Use the following chart to select the LED lights best suited for your indoor crops.

Light Color  Wavelength  Effects on Plants
Violet, Blue 400 to 520 nm
  • These wavelengths are the most absorbed by the chlorophyll in the plants
  • Both the quality and intensity of blue and violet light strongly influence plant growth and photosynthesis.
Red 630 to 660 nm
  • Exposure to light in this wavelength Increase the light absorption of the plant
  • Enhances vegetative growth, flowering, and budding
Far-Red 720 to 740 nm
  • Triggers germination and flowering
  • Associated with increased plant biomass  

Make sure to have a small percentage of UVA (Safe for humans) not UVB (Which is harmful for humans)

White LED Lights: Expert Recipes Optimize Plant Growth

White light, such as that emitted by a standard household light bulb, results when multiple light colors are mixed. For example, a combination of red, blue, and green LEDs produces white light. In converse, if you direct white light through a prism, the rainbow you see is the separate wavelengths light.

Experts who mix the recipes for white LED grow lights combine wavelengths that produce the Photosynthetic Active Radiation that maximizes plant growth. In fact, some LED grow lights that appear white actually produce more than 11 wavelengths of light. Additionally, you can find LED grow light recipes mixed especially for particular phases of plant growth, such as the flowering stage.
