What's the function of UV and IR on LED Grow Lights?
2023-08-22
UV (ultraviolet) and IR (infrared) are two specific wavelengths of light that are often included in LED grow lights for their specific functions in plant growth.
1. UV Light: UV light falls outside the visible light spectrum and is not visible to the human eye. In LED grow lights, UV light is typically included in small amounts. UV light has several functions in plant growth:
- Increased resin production: Exposure to UV light can stimulate the production of certain compounds in plants, including resin. Resin production is important for the development of essential oils, flavors, and aromas in plants.
- Pest and disease control: UV light can act as a natural deterrent for pests and pathogens. It can disrupt the life cycle of certain pests and inhibit the growth of harmful bacteria and fungi.
- Enhanced coloration: UV light can contribute to the development of vibrant colors in certain plant species, particularly flowers and fruits.
2. IR Light: IR light is also outside the visible light spectrum and is not visible to the human eye. In LED grow lights, IR light is often included in small amounts. IR light has several functions in plant growth:
- Increased photosynthesis: IR light can enhance the process of photosynthesis in plants, leading to increased growth and productivity. It helps plants convert light energy into chemical energy more efficiently.
- Deeper penetration: IR light has longer wavelengths than other visible light, which enables it to penetrate deeper into the plant canopy. This helps ensure that light reaches lower leaves and promotes more uniform growth.
- Heat generation: IR light produces heat, which can be beneficial in colder environments or during specific stages of plant growth that require higher temperatures.
It is important to note that excessive exposure to UV or IR light can be harmful to plants, so LED grow lights are designed to emit these wavelengths in controlled amounts to provide the optimal light spectrum for plant growth.
