Red Light vs. Blue Light Which Light Color Is Better For Plant Growth

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.

Which color light is best for plant growth?

Blue. 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 red light good for plant growth?

Red light can convey caution or danger or stopping at intersections, but for plants red light is highly effective at regulating growth and development. Within the photosynthetically active waveband (400 to 700 nm), sunlight emits roughly similar amounts of blue, green and red light.

What light is best for plants?

Offering low energy usage, low heat, and color optimized for growth, LED lights are the most efficient, effective, and customer-friendly way to grow plants at home than growing with fluorescent lights or incandescent lights. An LED grow light array.

Do red and blue lights help plants grow?

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. It's also essential to a plant's early life for seed germination, root growth, and bulb development.

Which color causes the most plant growth?

As it turns out, blue appears to be the color that had the most plant growth in both experiments. Green was the lowest in both experiments, of course. Red was the second highest, violet was the third highest, and orange was the second lowest in both experiments.

Why is red light most effective in photosynthesis?

Red light is more effective in photosynthesis because both the photosystems (PS I and PS II) absorb light of wavelengths in the red region (680 and 700 nm, respectively). Furthermore, blue light is absorbed by carotenoids, which pass the energy to the chlorophyll.

What lights do professional growers use?

Today, the most widely used lights for professional use are HIDs and fluorescents. Indoor flower and vegetable growers typically use high-pressure sodium (HPS/SON) and metal halide (MH) HID lights, but fluorescents and LEDs are replacing metal halides due to their efficiency and economy.

Will any LED light work as a grow light?

LED lights are more energy efficient and emit much lower levels of heat than other types of lighting. But can you use any led lights to grow plants? Generally, yes. ... White light contains a great mix for plants, so white LED bulbs will work to grow.

Can regular light bulbs help plants grow?

So, to answer the question, yes you can use a regular light bulb to help plants grow. Your best bet would be to place a few LED lights designed for plants near your plants that need a little extra light. Be sure not to overheat the plant or to give it too much sun.

Does blue light make plants grow faster?

Blue light helps with the plant's production of chlorophyll–the green pigment that traps light energy and is integral to photosynthesis. 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.

Why is blue light so bad?

Retina damage: Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration.

Why do plants absorb red and blue light?

12. Short answer: plant absorbs mostly "blue" and "red" light. ... To do this, plants have pigment molecules which absorb the energy of light very well. The pigment responsible for Page 7 most light-harvesting by plants is chlorophyll, a green pigment.
