Which Colors Of Light Spectrum Are Most Important For Plant Growth

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.

Which colors of light spectrum are most important for 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. These wavelengths encourage stem growth flowering and fruit production. Which color of the light spectrum are most important for plant growth. There are millions of photosynthetic receptors in a leaf of a green plant.

The longer wavelengths of light are red in color. You think of the sun as yellow it is much more than that. Have you ever thought about the light that makes the plant grow. For example different light spectrums are used for different types of growth in plants.

The most important wavelengths in the red spectrum are from 640 to 680 nm. Blue light is essential during a plant s germination phase. 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. A color spectrum of the light absorbed by the whole leaf shows that plants actually use a wider range of wavelengths including green.

Plants grow that is a given. Optimizing the color spectrum of light for horticulture. 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.
