Is Full Spectrum or red blue 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.

Correspondingly, what color 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.

In this manner, what is the difference between red blue and white grow lights? With a red+blue LED fixture, there is no far red and so plants are sometimes shorter, especially during light-limiting conditions, than under fixtures that include some far red. White LEDs emit some far red, and so plants may be slightly taller, and some plants may flower slightly earlier, than under red+blue LEDs.

Consequently, do red and blue 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 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 seedlings need red or blue light?

Light Color

Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly). Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).

Do plants grow better in red light?

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.

Are all LED lights full spectrum?

Often referred to a purple, or blurple, LEDs, the manufacturers of these lights refer to them as “full spectrum”. But they are not. Even if they have diodes in many other colors, they are not really full spectrum.

Why is blue light best for plant growth?

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.
