UV and Infrared Light for Growing Plants

Everything you need to know about UV and infrared growing lights!

When it comes to the lighting, you choose to use in your grow room. You have a lot of choices. But, of course, what you choose will also depend on various factors, including what type of plants you are growing, where you are growing them, how many plants you are growing, the size of the grow room and your budget.
In the following article, we’ll take a closer look at infrared lighting, how it works, and some of the pros and cons of using it. We’ll also look at UV lighting and its pros and cons, comparing the two different types of lighting.

Infrared is an important part of the electromagnetic spectrum, but it is technically outside of the light range, which is visible to the human eye without any mechanical aids. On the far end of the light spectrum, you have infrared light. Infrared lighting can’t be seen but can be felt as heat.

Both blue and red light is important for plant growth. However, research suggests that infrared light combined with blue light and red light can boost the rate of photosynthesis. This effect is known as the Emerson effect.

There are two different chemical procedures that both contribute to plant growth. These procedures are known as PS1 and PS2. Plants exposed to blue and red light along with infrared light showed an increase in photosynthesis, but when these light wavelengths are absent, growth can be stalled.

Infrared can be effective at promoting more robust stem growth and node spacing which leads to more flowers. However, a large percentage of infrared light is felt as heat which can cause your plants to stretch, become distorted, and even kill your plants. Therefore, finding the right balance of infrared light is vital.

  • Should You Use UV and Infrared Lights In Your Grow Room?

Absolutely you should! Some factors that you’ll need to consider when using UV lights:

1. Your plant's specific light needs.
2.Height and space limitations in your grow room.
3.Safety precautions regarding your exposure to UV light.
4.Your budget requirements and how much you have to spend, especially with any new grow rooms.

Some factors that you’ll need to consider when using infrared lights:

1.Your plants need regarding excessive heat, which can be an issue with IR lights.
2.Your plants shape because IR light can cause plants to stretch and grow more than other light.
3.Safety precautions regarding your exposure to IR light because of the heat generated in potentially confined spaces.
4.Your budget. While IR light is beneficial, it isn’t 100% necessary and could stretch your budget beyond your means.
