Which Colors Of Light Spectrum Are Most Important For Plant Growth

There are millions of photosynthetic receptors in a leaf of a green plant.

Which colors of light spectrum are most important for plant growth. How do we know this. The longer wavelengths of light are red in color. Blue light is essential during a plant s germination phase. Have you ever thought about the light that makes the plant grow.

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. 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. How plants respond to light is important in understanding photosynthesis. Optimizing the color spectrum of light for horticulture.

These wavelengths encourage stem growth flowering and fruit production. 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. Plants grow that is a given. The light spectrum that those plants use is completely different than what you think.

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. 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.
