What is the difference between red and blue LED grow lights?
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.
Why are LED grow lights different colors?
As plants mature and go through their growth cycle from seedling, to adult, and then flowering and fruiting they use different color spectrums so the ideal LED light is different for each stage of growth. The best color spectrum also depends on the type of plant you are trying to grow.
What does red LED 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 .
What Colour grow light is best?
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.
Is it better to grow plants under blue and red light?
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.
Why are red LED lights bad?
Those red LEDs were made with a substance called AGA (aluminum gallium arsenide), which is toxic in concentrated amounts. If you are directly exposed to this material on work sights or through contact with broken bulbs, it can be hazardous to your health.
Why does blue light help plants grow?
Blue light produces more lush greenery. Blue light is necessary for plants to regulate plant growth, as it helps to create strong stems and also helps create the chlorophyll necessary for plant processes. In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light.
Are red and blue LED lights 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.
Is blue LED 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. Indoor foliage plants benefit from having 12 hours of light per day.
Will blue LED grow plants?
Blue LED Lights Blue light is a specific light wavelength that is needed by plants for photosynthesis and growth and is ideal for use on seedlings and young plants. Blue LEDs are far more efficient than they were a few years ago and are useful in grow light systems in combination with other light wavelengths.
Does blue light make plants grow faster?
What is this? In other words, blue light is easier for a plant to absorb and use the energy in photosynthesis. So, blue light increases plant growth and makes the plant reach maturity faster. This is why blue light is especially important for seedlings and young plants.
Is red or blue light better for photosynthesis?
light. In contrast, blue light is considered equally effective as green or red light at driving photosynthesis. Thus, while blue light can appear somewhat dim to us, it has high energy and is useful for plant growth applications.
How much red light do LED grow lights emit?
With arrays of light-emitting diodes (LEDs), the proportion of red light can range from 0 to 100 percent. Many commercial LED fixtures developed for plant growth applications emit a large proportion of red light, with 75 to 85 percent of the light spectrum commonly emitted in the red region.
What happens if you grow under red light?
Red light on extension growth. Many plants grown under only red light, such as plants grown indoors under only red LEDs, have a stretched, elongated appearance; the leaves are thin and large and plants become tall. In most cases, plants grown under only red light do not have desirable growth characteristics.
Why do LED lights emit a lot of red light?
The primary reasons why LED fixtures emit a lot of red are 1) red LEDs are among the most efficient at converting electricity into photosynthetic photons, 2) chlorophyll strongly absorbs red light, thus it is effective at photosynthesis, and 3) red LEDs are relatively inexpensive.
What is the difference between red/blue and broad spectrum LED lights?
So broad spectrum light is not only more pleasing to the eye, but also makes it easier to work and assess plant health. So, while you can use a red/blue LED in sole source applications, with human health and plant scouting being affected, we highly recommend using a broad spectrum LED.
