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.

Moreover, do red LED lights help plants grow?

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.

Moreover, can plants grow under 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.

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.

Is blue or red light better for seedlings?

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).

How far should LED grow lights be from plants?

12 to 18 inches
