What Is Infrared Light?
Did you know that roughly 49.4% of the light that reaches the surface of the earth is what we call infrared (IR) light, or heat radiation?
Infrared light is part of the electromagnetic radiation spectrum, where wavelengths are longer than those of visible light. Typically, IR wavelengths range from 700 nanometers to 1 micrometer. These longer wavelengths are one of the main ways that heat is able to be transferred from one source to another. Longer wavelengths of infrared light produce more heat.
Infrared light is made up of a range of wavelengths:
- Near-infrared — Wavelengths that fall in this range are the shortest in the IR light spectrum. These wavelengths are closest to being visible, and they are used in common objects like your television remote control. Near-infrared lights are not hot.
- Mid-infrared — Wavelengths in this range are warmer than those in the near-infrared range, but are still not considered hot. Using special equipment, scientists and astronomers are able to use mid-infrared light to better observe and study planets and other celestial objects.
- Far-infrared — Wavelengths in this range are hot. This is the type of IR light that is used within grow lights in order to help plants grow and bloom.
How Do Different Grow Lights Use Infrared Light?
LEDs are made up of several diodes, some of which are capable of producing IR light. Most LEDs typically only produce visible light like blue and red wavelengths. So in order to emit infrared light, growers need to add infrared emitting diodes.
- High Intensity Discharge (HID) Grow Lights
HIDs provide a lot of infrared light naturally, just by plugging them in. Your plants light via chemical reaction when electricity arcs between two electrodes interact with ionized gas or plasma inside of a bulb. Depending on the type of gas being used, you'll produce white/blue light used for metal halide (MH) lights and ceramic metal halide (CMH) lights, or warm yellow/orange light used in high pressure sodium (HPS) lights.
In between all those wavelengths of light, though, is IR light. In fact, roughly 30% of the light emitted from HID lights is IR light.
In the same way as HIDs, T5 lights produce light with an electrical current and a chemical reaction. That said, growers can incorporate infrared LED grow light diodes with their T5 light fixtures, or buy separate bulbs for their fixtures that provide IR light.
How Does Infrared Light Affect Plants?
- Better Blooming
Researchers and horticulturists have found that infrared light helps plants bloom. This is due to a type of photoreceptor that plants contain called phytochromes. Phytochromes help regulate processes that are critical to plant development, such as leaf expansion, stem growth, and blooming- and IR light is what helps stimulate that growth.
Growers can use infrared light to “manipulate” your plant's senses, thus altering the plants’ growth process. Phytochromes react strongly to infrared light, so exposure to this light will make a plant think that it is experiencing the same amount of light that it would if it was growing outside during any given season.
IR light is a big reason why you don't have to wait for the summer to grow plants, nor the winter to harvest them. They get the IR they need to grow from your lights, not what's seasonally available by the sun.
- Increased Plant Growth
Another benefit of exposing your plants to infrared light is increased plant growth. Because plants need sunlight for photosynthesis, they have automatic defense processes that kick in when their exposure to sunlight is threatened by other plants.
When plants are covered by other plants, they can lose direct sunlight exposure, and they tend to receive light through the taller plants’ leaves. This results in your plants taking in high levels of infrared light, which triggers the plants’ survival mechanism, subsequent stretching and growth.
When combined with other forms of light that aid in branching- like all blue LED grow lights- and producing a desirable plant shape, IR light help aid in rapid plant growth.
