The truth is that white light works great to grow plants. Red and blue wavelengths are the most important for photosynthesis, but plants use all wavelengths of light. And white light provides all wavelengths.4 Oct 2021
Can you use white LED lights to grow plants?
While COB and white light LEDs can grow plants, with all of the energy wasted in the green spectrum they aren't necessarily the most efficient. White LEDs only produce 40% of usable light and the rest is wasted in power consumption and heat.25 Sept 2016
Do white LED lights work as grow lights?
Can white LED lights grow plants? Yes white LED lights can be used to grow plants but they also need both blue and red light spectrum mixed in to make sure they grow fully.
What color LED lights are best for growing?
Blue is the most important light for plant growth, because it is readily absorbed by chlorophyll and converted into energy through photosynthesis. That said, blue light on its own is not nearly as effective as blue combined with red.12 Jun 2020
Which color light is best for plant growth?
- Violet-blue light in the 400 520 nanometer range encourages chlorophyll absorption, photosynthesis, and growth.
- Red light in the 610 720 spectrum range promotes flowering and budding.
Do plants grow better in white or yellow light?
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 like white LED light?
Plants preferentially absorb red and blue light. Much of the light produced by "white" LEDs are in spectra (colors) that plants do not use. This unused light is just converted to heat within the leaves, requiring lower environmental temperatures to maintain optimal leaf surface temperatures.
Do plants like colored LED lights?
Plants grow best when they have all colors of light. They want mostly red and blue (with about 5 times as much red as blue), with a good amount of light in every other color as well.12 Jun 2020
What color light is best for leaf growth?
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 color grow light should I use?
Blue light is necessary for vegetative growth while red light is needed to promote flowering and fruit production. The color temperature of a grow light helps you understand if the overall output of the grow light trends towards blue or red.12 Apr 2018
Are white LED lights good for plants?
When combined with the 20%-40% efficiency loss, "full spectrum" white LEDs are less than half as efficient for growing plants than the correct mix of pure-color LEDs-- white LED grow lights force you to cool your growing environment more, just like HPS and MH, losing a lot of the other advantages LEDs offer.
