Photosynthesis is the process used by living organisms to convert light energy into chemical energy. Choosing the correct color of light (CRI) or spectrum when selecting an led grow light can be an important factor when bringing balance to your grow environment. Spectrum can play an important role in crop production, different wavelength nanometers effect different characteristics of growth. Full spectrum lighting will produce optimal environmental lighting needs for plants, the vast spectrum allows plants to absorb light wavelengths as needed from all parts of the spectrum not limiting the plants ability or overall productivity efficiency. When selecting your grow light make sure to check the color of light with a spectral radiometer, to make sure you are receiving as much of the spectrum as possible. Some LED company’s and lighting manufactures are limited to what spectrums of light they can produce and tailor their marketing toward there nanometer of light output.
When choosing a specific spectrum because of the flexibility of LEDs and tuning a directed spectrum at a certain crop you must take into account the limiting factors. It is important to remember that everything has a cause and effect, tuning specific spectrums for plants that have evolved with full spectrum light for millions of years can introduce new problems. Yeah, it’s great that we can tune a spectrum and produce a desired structure in the plant by restricting some of the spectrum and giving the plant specific wavelengths of light, however, the most important aspect when growing is your end result or final harvest. Spectrums of light will effect overall, taste, smell, yield, and more importantly the nutritional value of your end product.
Spectrums of light with fuller spectrums closest to the suns spectrum absorb 30% more effectively then artificial spectrums. Combinations of spectrum and intensity produce Kelvin combos that effect the plants characteristics and growth, are also responsible for helping the plants defense against bugs, disease, and deficiencies within the plants. Light energy is all usable energy to some extent, with the understanding that some wavelengths of light are better absorbed and used more efficiently. Plants will accept wavelengths of light in the300-800nm Range, obtaining as much of this spectrum as possible with controlled intensity along the spectrum for enhanced growth is key.
You must understand when looking for light sources, you are not simply growing something. It is not a 1+1=2 kind of equation. You are creating something, you are putting a living organism in a controlled environment and influencing and enhancing its characteristics to a desired end product. In doing this you must factor in the smallest minute factors, as to the fact that your Plants Spectrum Availability is key in achieving a well-balanced environment to producing beautiful plants and superior quality. PSA is Important when considering color of light, take into account the 400 plus key nanometers of frequency between 300-800nm range that plants utilize. Look for quality full spectrum light sources that deliver high combinations of light frequency to give your plants a fuller PSA Rating and keep your plants and genetics thriving and healthy.
I will leave you with this in conclusion… think about the sun, it rises and sets. In doing so, every day from the time the sun comes up till the time it sets the frequencies of light are constantly changing. The spectrum remains full, but the intensity along that spectrum changes throughout the day changing the light appearance or Kelvin as we know it. This ever changing frequency of energy plays and important role in how living organisms or plants absorb the combination of light and utilize the energy given in the various combinations.
To ask one what color of light is right for you, it’s a light that doesn’t exist or at least artificially. Because the light we need is a miniature sun that plugs into 120-240 volt and mimics the sun 100% or as close to it as possible. For now we are left with the available technology, with that I would choose the light with the fullest spectrum and go from there.
“Remember you’re not growing 1+1=2, you are creating in doing so make sure your canvas is vast and open. To create something with limits is to create something within a box, Plants don’t grow in a box they grow in an environment.”
What else should you be looking for in a LED grow light?
OK so now that we know what LEDs should be present in our ideal LED grow light, we can go ahead and press that ‘pay now’ button and begin fantasizing about how impressed our neighbors will be with our exceptionally green fingers, right? Not so fast…. there’s more…
High-power LEDS – For the serious horticulturalist, avoid anything that is below 3-watts (just as a point of reference, the typical electronics LED is 0.02-watts or less). The current standards in LED grow light today are 3-watt or 5-watt LEDs.
Brand-name LEDs – It is important also for LED grow lights to only contain brand-name LEDs. This is because big-name companies extensively test their LEDs to ensure that their life expectancy is within the range that they specify. They have a reputation to uphold after all!
Metal core, cooling fans and heat sink – Even though LEDs produce far less heat than other types of lighting, they still produce some heat. While this is unlikely to be detrimental to plant growth, it is detrimental to the LED lifespan. The way high-quality manufacturers have tackled this is to place each LED on a metal base attached to a heat sink providing a path for heat to escape, and complemented by the presence of electric fans. These are an absolute must for high-power LEDs.
Constant-Current – Cheap LED grow lights are powered by constant voltage circuitry. As the LED’s temperature increases, its voltage tends to drop, causing a cheap LED driver to compensate by increasing the voltage it supplies, inadvertently increasing the current as well. This increased current ages the LED prematurely reducing its life expectancy. The better HID grow lights have circuitry that keeps the current steady instead of the voltage and probably gives you better value for money in the long run.
The ‘Perfect’ LED grow light
Full spectrum LED GROW LIGHT(VANQ) —is the future innovation of grow lights here today, before it’s time. Powered by the highest proprietary technology of the Alta LED chip, this is technology that in just now being introduced to the world. Finally, the sun shines inside.
