What colors of light are most beneficial for plants? 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.
Is blue or red light better for plants?
While red is most efficient for photosynthesis, having only red light would result in poor growth such as very elongated stems, so blue is added to keep plants compact and a more typical shape.
Will LED lights help plants grow?
Just like fluorescent and incandescent bulbs, LED bulbs produce light that is needed by plants. You can get good growth with just one or the other of the color waves, but utilizing both will result in bigger yields and healthier plants with quicker growth.
What does green light do for plants?
Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture. Sometimes one may hear that plants don't use green light for photosynthesis, they reflect it. However, this is only partly true.
Is pink light good for plants?
A new wave of research shows that “pink” light – a mix of red and blue wavelengths is all that a plant really needs to grow. “So we developed these lights to correctly match the photosynthesis needs of our plants. We get almost 20 percent faster growth rate and save a lot energy.”

What does red light do for plants?
red light is highly effective at regulating growth and development for plants . Red light helps to flower and fruit and prolong flowering.It can greatly enhance the photosynthesis of plants and promote the growth of plants. but if plants are grown under only red light .
Why are plant lights pink?
White LED fixtures create a more pleasant environment, and the spectrum is similarly useful to plants as purple light, but fixtures are usually less efficient. Red+white LED fixtures create a pinkish light that seems to be a good compromise between efficacy and lighting preferred by people.
What kind of lights do plants need?
When growing most houseplants, use light bulbs between 4000 and 6000 Kelvin, as the bulb's color temperature will borrow from a full spectrum of colors—cools and warms. With these lights, you can actually mimic the growth you would get in a greenhouse or outdoors.
Is yellow light good for plants?
Plants absorb some yellow and orange light, but these wavelengths are not the most important for photosynthesis. Seedlings given yellow or orange light alone will not be able to create carbohydrates, and so will not grow and thrive.
Do plants grow better in red or green 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.
Is blue light good for plants?
The effect of blue light on plants is directly related to chlorophyll production. Plants that receive plenty of blue light will have strong, healthy stems and leaves. Red light is responsible for making plants flower and produce fruit.
Are purple or white lights better for plants?
White LED fixtures create a more pleasant environment, and the spectrum is similarly useful to plants as purple light, but fixtures are usually less efficient.
What is purple light for?
One of the less common colored bulbs you'll see is the purple light bulb. Also useful (especially with orange) for Halloween, purple lights are also used in October by those trying to raise awareness of the problem of domestic violence. (October is Domestic Violence Awareness Month.)
Is all blue light bad?
Almost all blue light passes straight through to the back of your retina. Some research has shown blue light may increase the risk of macular degeneration, a disease of the retina. Research shows blue light exposure may lead to age-related macular degeneration, or AMD.
What color temperature is best for plants?
As a general recommendation, choose a full spectrum grow light with a color temperature in the blue range (5,000 - 7,000K) to promote vegetative growth and choose a color temperature in the red range (3,500 - 4,500K) to promote fruiting and flowering.
What color are LED grow lights?
It is the same light. Both red and blue LED chips are off-the-shelf products, meaning quickly accessible in countless factories in China. And with the combination of red and blue LED chips we get: purple or pink light that has become the visual synonym of the LED grow light industry.
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.
What happens if a plant gets 24 hours of light?
The Dark Side of Photosynthesis
During light reaction, the plant absorbs light and turns it into energy. Because dark reactions do not require the absence of light, plants will remain healthy when exposed to light 24 hours a day. There are some plants, however, that will survive but not thrive without darkness.
Does TV light affect plants?
A TV shouldn't have any negative effect – or indeed, any positive effect – on your plant. It doesn't output anything harmful, but its light is not enough for your plant to grow by. If you want to grow light-loving plants in a dark living room, you will have to invest in a grow bulb to give your plants all they need.
What kind of light do indoor plants need?
Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum. They're excellent for seedlings as well as houseplants, culinary herbs and other plants.
