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

LED Grow Light Coverage Area Guide

I have already stated that there are many factors that can affect the coverage area of LED grow lights, here is a rough guide to what I think are suitable grow spaces for a given wattage of light. There are many LED manufacturers and many more wattages of lights so here is a list of common sizes. All lights listed are 3 spectrum(Red+Blue+Orange) LED grow lights. By keeping these guidelines in mind with your growing effort, you will find that your results will match or exceed your expectations.

Light Wattage Vegetative Stage Coverage Flowering Stage Coverage
90 Watt 4′ by 4′ 2′ by 2′
120W~200w 5′ by 5′ 3′ by 3′
300W 6′ by 6′ 4′ by 4′
600W 7′ by 7′ 5′ by 5′

Blue LED Grow Light Vs Red LED Grow Light

Indoor plant gardens require adequate amounts of light to promote healthy growth processes within plant structures. And while sunlight may not be available in needed amounts, specially designed LED grow lights can simulate needed light energy for plant processes. When deciding between blue or red LEDs, the particular needs of the plant can help in determining which will work best.

Light Energy
Light in its most natural form comes from the sun. Sunlight contains the full balanced spectrum of energy wavelengths so crucial for maintaining life on Earth. According to the Gardener’s Supply Company, plant processes rely on the energy contained inside light to produce food and support the plant body. Different types of light produce various energy wavelengths that affect plant structures in different ways. LED lighting actually sits just below the visible light spectrum, so the energy contained inside LED wavelengths is thermal, or radiant energy.

LED Light
LED stands for light-emitting diode. This light-emitting feature refers to the degree of heat that radiates from an LED bulb, according to the Gardener’s Supply Company. This form of energy is made up of longer and slower wavelengths than those that form visible light. As a result, living cells actually absorb LED wavelengths, which has direct effects on cell metabolism processes. The use of red and blue lighting for indoor planting purposes combines the thermal effects of LED wavelengths with blue and red energy wavelengths.

Function
Of all the colors contained inside the visible light spectrum, plants are most responsive to the energy contained inside red and blue wavelengths, according to the University of Missouri Extension. Both types of energy play vital roles within plant photosynthesis processes where light energy is absorbed and converted into carbohydrate materials. These carbohydrate materials are then converted into food for the plant. The metabolism processes involved in making plants strong and healthy rely on the energy contained inside blue and red light waves.

Blue Light
The wavelengths contained inside light are made up of photon energy particles. The energy contained inside blue LED light plays an essential role in stimulating and regulating seedling growth processes, according to the Plant Physiology Information website. Chlorophyll pigments contained on leaf surfaces are responsible for absorbing incoming light energy. These areas rely on the energy contained in blue light waves to create the chemical reactions that take place in photosynthesis. Blue light waves also promote the production of chlorophyll materials on leaf surfaces.

Red Light
According to the Gardener’s Supply Company, red LED light waves help to stimulate overall growth throughout the structure of a plant. When growing vegetative or flowering plants, red wavelengths help to stimulate fruit and flower growth processes. This form of energy is also beneficial in stimulating seed and bulb growth, though a balance of blue light is needed to properly regulate early growth processes. In general, both red and blue light waves are needed for the health and growth of plants, so balanced amounts of both provide an ideal environment for new and established plants.

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.

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.
