The Definitive Guide to Grow Light Spectrum
Choosing the right
light
spectrum and color temperature for your plants is important.
Light needs will change for the phase of growth your plants are in, so you may need to switch lights as they enter flowering, depending on the light you’re using. After you’ve decided on a light source, i hope this guide helps you in determining what bulbs to use and when.
What is Grow Light Spectrum?
The use of led grow lights in crop farming has recently seen substantial growth. However, choosing the right light spectrum for plants and knowing how they affect photosynthesis, can be challenging and oftentimes confusing. See all available cannabis grow lights by bios this article aims to help you understand the light spectrums needed for plant growth and how full spectrum led lighting is now widely used for crop production. We’ll address what broad-spectrum lighting is, how different grow light spectrums affect different stages of plant growth, and its effect on cannabis production.

But not all sunlight that reaches the earth’s surface is vital to plant growth. In fact, the light needed for healthy plant growth only makes up a small portion of the electromagnetic spectrum – which is visible light. In this post, we’ll explain exactly what visible light is and go for a deep dive into everything you need to know about full-spectrum light for plants.
Light is obviously a critical component in growing plants, but it’s about quality as much as it is quantity. Plants can only absorb and utilize certain spectrums of light. The spectrum of light that plants use is known as photosynthetically active radiation (par) and includes wavelengths from 400-700 nm. So, the light produced that doesn’t fall within this range cannot be absorbed by the plants and utilized for growth. Additionally, different wavelengths of light can trigger different responses in the plant. For example, red light is effective for increasing the total size of a plant, but when used alone can result in “stretched” plants that are tall with thin leaves.
A grow light is an electric light to help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye). Outdoor conditions are mimicked with varying colour temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation (e.
