Which Colors Of Light Spectrum Are Most Important For Plant Growth

A color spectrum of the light absorbed by the whole leaf shows that plants actually use a wider range of wavelengths including green.

Which colors of light spectrum are most important for plant growth.

If we start at the blue end of the spectrum and move towards the red we ll get a good idea of how light in different parts of the spectrum influence plant growth. Botanists have gained a solid understanding of how plants use different color spectrum components during their growth cycles with the following generalizations holding true in large part across most plants. Have you ever thought about the light that makes the plant grow. These wavelengths encourage stem growth flowering and fruit production.

How do we know this. The most important wavelengths in the red spectrum are from 640 to 680 nm. There are millions of photosynthetic receptors in a leaf of a green plant. Which color of the light spectrum are most important for plant growth.

The longer wavelengths of light are red in color. Blue light is essential during a plant s germination phase. It is true that blue and red are important and represent most of the light used by plants but other colors including green and yellow are also used for photosynthesis. Most people working with indoor plant operations are more familiar with blue and red lights but it s a good idea to understand how the overall color spectrum affects plant growth.

You think of the sun as yellow it is much more than that. Plants grow that is a given. For example different light spectrums are used for different types of growth in plants.
