What is plant growing wavelength?

Here is the knowledge necessary to grow plants successfully.This time, I would like to introduce the wavelength of plant growth.

Factors required for plant growth

There are two main factors involved in plant cultivation.
"PPFD (photosynthetic photon flux density)" and"plant growth wavelength"are these two factors.

This page is one guide for purchasing plant growing lights.
I will explain "Plant growing wavelength".

On another page,"The difference between the way people perceive the light of plants and the eyes of plants".
I am explaining about "PPFD (photosynthetic photon flux density)".

If you also see it, you can better understand the selection of plant growing lights.
Please refer to it as you can deepen it.

Be aware of chlorophyll (photosynthetic pigment)!

Photosynthesis is essential for plant growth.
What is involved in photosynthesis, such as chlorophyll"Photosynthetic pigment".
The light used for photosynthesis is absorbed by this"photosynthetic pigment".
Plants grow by photosynthesis.

That is, the light (high absorption rate) preferred by chlorophyll (photosynthetic pigment).
By giving it to plants, you can grow plants efficiently.
This is called "plant growth wavelength."

About plant growing wavelength

For chlorophyll, it is mainly in the blue light region (400-500 nm in wavelength).
It absorbs light in the red light region (600-700 nm in wavelength).
And since the absorption efficiency of the light in the green light region (500-600 nm in wavelength) during that time is poor,
The leaves look green.

However, even green light is used for photosynthesis as long as it is absorbed.

Other than chlorophyll
When photosynthetic dye is absorbed

The energy of light absorbed by photosynthetic pigments other than chlorophyll.
When transmitted to chlorophyll, that light energy is also used for photosynthesis.

For example, a photosynthetic pigment called phycobili which red algae has
Absorbs green light, which is transmitted to chlorophyll
Used efficiently for photosynthesis.

Conclusion

Another important element of plant growth, "PPFD (photosynthetic photon flux density)" is also important
