Do Plants Always Require UV & IR Light?

Everyone knows that only full spectrum LED grow lights can help plants grow healthfully.

Whenever it comes to full spectral range, two controversial concepts, Ultraviolet and Infrared, are addressed more frequently, in conjunction with their meaning.

The use of UV and IR supplemental LED lighting is quite important when it comes to achieving a healthily grown plant. Do reach out to a reputable manufacturer to make your purchase.

What are UV and IR light?

Ultraviolet Radiation (UV)

Ultraviolet radiation light is a form of electromagnetic radiation emitted by natural sunlight. This light is divided into three sections of varying wavelengths:

  • UV-A wavelengths are 400nm-315nm.
  • UV-B wavelengths are 315nm-280nm.
  • UV-C wavelength range: 280nm-100nm

Infrared and far-red light

Infrared and far-red wavelengths of light are found at the far end of the spectrum (>700nm).

The wavelengths of infrared and far-red light are extremely long and contain very little energy.

Infrared wavelengths are invisible to the naked eye and can only be felt as heat.

The Advantages of UV and IR Light

Plants require a lot of UV light to grow. UV, in low doses, aids in the production of oils that produce the desirable aromas and flavors in your crop.

This is just what the plant can produce to shield itself from further UV exposure. Plants, just like humans, produce their normal sunblock.

The primary benefit of IR light is the enhanced PAR which is due to an Emerson Effect.

With high rates of photosynthesis, the plant receives more energy to grow stronger and bigger.

Due to the shade avoidance response, plants exposed to IR light might well begin to grow outward.

The Drawbacks of UV and IR

Too much UV-A and UV-B could restrict photosynthetic activity, making the plant grow much less efficiently.

Not just that, UV light can also physically harm crops. UV light can cause plant cells to die by damaging their DNA, thereby, affecting the plant's growth and appearance.

Excess IR radiation could also be a problem because a significant proportion of IR radiation is perceived as heat by plants.

Excessive heat can stress your plant and destroy your crop.

Furthermore, the stretching of the stems and leaves may be excessive due to the shade avoidance response.

While growing plants, I am sure we all want healthy and vigorous plants that can withstand the weight of large flowers.

As a result, the plants do not require UV and IR light all of the time. This is because UV and IR lights are beneficial in certain situations.

Therefore, proficient growers only utilize discrete UV and IR illumination bars to precisely control their light source and reap the full advantages of UV and IR lighting.

Do you need to enhance your plant growth?

If you are serious about reaping the benefits of UV and IR lighting, you should invest in UV and IR supplemental LED light for your grow room.

A full-spectrum LED, along with supplemental UV or IR light bars, will significantly help your plants grow healthily. Do contact us to place your order today.
