What is the best light spectrum for plant growth?
Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.
Do plants grow better under red or blue light?
The color of light DOES affect plant growth, but the effect is more noticeable under low light intensity. Red & blue light are most effective for plant growth, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.
What is red spectrum light?
Red Light Spectrum (600–700 nm) Red light is known to be the most effective light spectrum to encourage photosynthesis as it’s highly absorbed by chlorophyll pigments. In other words, it sits in the peaks in chlorophyll absorption.
Do red blue LED grow lights work?
Red/Blue LEDs Since photosynthesis peaks in the red and blue wavelengths it makes this spectrum, not only the most efficient for plant growth, but also the most energy efficient.
Do red and blue LED grow lights work?
Blue promotes root development and strong, stocky plant growth. When you blast your young plants with blue, you prepare them to sustain a ton of buds in the future. Red light, on the other hand, does its best work in the flowering phase. A higher intensity of red promotes a higher yield.
Are full spectrum LED lights good for plants?
Many LED lighting suppliers will say that full-spectrum LED grow lights are the best option for growing plants because they mimic the natural light from the sun. “Plants have grown under sunlight for millions of years.
How do I know if my LED is full-spectrum?
To be full spectrum, the light should emit all the wavelengths of light like a rainbow and in the same proportion as natural sunshine. The multiple wavelengths combine into white light. If just some of the wavelengths are present, the light has a partial or distorted spectrum.
Can you use white LED lights to grow plants?
White LED grow lights are good if you’re looking to illuminate your home or office as this efficiency loss is easily justified by being able to see comfortably, but for growing plants they are wasteful. Plants preferentially absorb red and blue light.
What color are full spectrum LED grow lights?
Broad-Spectrum LED Grow Lights These lights are white in appearance, though there are no actual white wavelengths. The white hue is a mix of blue, red, and green wavebands.
