How the Sunlight Effects Plant Growth

  • 200 – 280 nm UVC ultraviolet range which is extremely harmful to plants because it is highly toxic.
  • 280 – 315 nm Includes harmful UVB ultraviolet light which causes plants colors to fade.
  • 315 – 380 nm Range of UVA ultraviolet light which is neither harmful nor beneficial to plant growth.
  • 380 – 400 nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.
  • 400 – 520 nm This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. (promotes vegetative growth)
  • 520 – 610 nm This range includes the green, yellow, and orange bands and has less absorption by pigments.
  • 610 – 720 nm This is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. (promotes flowering and budding)
  • 720 – 1000 nm There is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.
  • 1000+ nm’s 600w LED grow light 3w, LEDs Wavelength: Red 660nm + 630nm, Blue 475nm + 430nm, Orange 615nm, White 4500k, the design of this new all in one Red+Blue+Orange+White(RBOW) grow light allows maximum level photosynthesis food production, growth and flowering all in one. It is the new RBOW system providing maximum plant health, beauty and productivity.

Picture Show The Most Important Wavelength of Light

Chlorophyll a, the most important light-absorbing pigment in plants, does not absorb light in the green part of the spectrum.

So as you can see:
Make up of an ideal led panel:
2% UVB Leds for resin and tric production. 380mn
6% Royal Blue Leds 455mn
12% Blue Leds 470mn
30% Red Leds 627mn
50% Far Red leds 660mn

Sunlight contains 4% ultraviolet radiation, 52% infrared radiation and 44% visible light.
I would stay away from amber leds I have seen I studies that show an increase in hermaphrodites.
I will go into Chlorophyll b when I can find the graphic again.

Welcome to custom made your led grow light from, customized items with color spectrum optional: Red: 660nm + 630nm, Blue: 475nm + 430nm, Orange: 615nm, White: 4500k, IR, UV.

Why Light Wavelengths Matter When Choosing A Grow Light

Does the type of light a grow light emit really matter when it comes to growth and production? To discover the answer it is best to find out what a light wavelength is and why a plant needs light to begin with. Let’s go back to school for a little biology lesson.

A lights wavelength is the distance between the two nearest peaks (the top of the wave) or the two nearest troughs (the bottom of the wave). A lights wavelengths measurement can tell you what the color of the light is. Visible light is measured between 400-700 nm or 400-700 nanometers (a billionth of a meter).The shorter the wavelengths of visible light are more violet in color, the longer the wavelength of visible light are redder in color. Wavelengths shorter than 400 nm are known as ultraviolet (UV) waves whereas wavelengths longer than 700 nm are known as infrared (IR) waves. Most of the light wavelengths plants use for photosynthesis is between 400-750 nm because UV waves and IR waves can actually damage plant life. The primary colors used are blue and red whereas green wavelengths are reflected (giving plants their green color.)

Photosynthesis is the process of converting light, water, and carbon dioxide into sugar by plants, algae, and bacteria. These sugars are used to make adenosine triphosphate (ATP) which is the fuel for all living things. In the outside world, the sun does the work of supplying plants with the light they need but if you are growing indoors what would supply the most adequate light needed for photosynthesis?

Engineers used six different light wavelengths, primarily blues and reds, to design the very first LED grow light. This light was designed using only colors that plants need and use for photosynthesis. Traditional white lights emit only 18% of usable light for plants and most of the LED grow lights on the market only emit blue and/or red wavelengths. The newest model, the 600w led grow light 3w, is the most spectrally rich, highest performing plant light source in the world. By designing the led grow light using only the wavelengths that plants need and keying in on the specific light wavelengths (blues & reds) that they use most for photosynthesis, we now have an indoor grow light that will not only grow plants but will also help in production and blooming.

The LED grow lamp was also designed to be environmentally friendly – no lead, no mercury, no glass, no white light pollution, low heat output, made of recyclable plastic, and is safe around kids and pets.

With having a better understanding of what light is for plants you can have a better understanding of why the color wavelengths of your grow light are so important. Next time you are looking for a grow light, make sure the light it emits is what your plant needs. Better yet, stick with the LED grow lights and you know you will have the best light for your plants in the world.
