Read on to find out and see if green light is beneficial or disadvantageous for your plants.

Green light would be defined as radiation with wavelengths ranging between nm. Green light within photosynthetically active wavebands is between nm. As mentioned, there are other kinds of lights, which as blue nm and red nm.

We would often find red and blue light mostly for LED fixtures made for plant growth applications. So, why are plant leaves green, then?

Light transmitted from one leaf is available to leaves below it, so photons are useful in plants. Green light can be defined as radiation with wavelengths between and nm. Green light is within the photosynthetically active waveband of to nm, yet its effects on plant growth and development are not as well understood as blue to nm or red to nm light.

The luminous efficiency curve illustrates our sensitivity to the different wavelengths of light Figure 1. From a photon perspective, sunlight emits roughly equal amounts of blue, green and red radiation. In contrast, within the photosynthetically active waveband, light emitted from conventional electric lamps cool-white fluorescent, metal halide and high-pressure sodium all emit 53 or 54 percent green light.

This is not a coincidence; these lamps were developed for human vision and because we are so sensitive to green light, the lamps appear relatively bright to our eye. Green light and plant growth. Many LED fixtures for plant growth applications emit mostly, or only, red and blue light.

There are three primary reasons for this: 1 red and blue LEDs are more efficient than green LEDs at converting electricity into photons, 2 red and blue photons are often considered the most effective at stimulating photosynthesis on an instantaneous, single-leaf basis see relative quantum efficiency curve, Figure 1 , and 3 green light is poorly absorbed by the two types of chlorophyll when extracted in solution also in Figure 1.

Light transmitted through one leaf is subsequently available to leaves below, so those photons are still potentially useful to plants. In addition, pigments other than chlorophyll absorb green light to make it useful for photosynthesis. Therefore, green photons are essentially as useful to plants for photosynthesis as red and blue photons.
