Myth: Plants Only Need Red and Blue Light
Ever since natural sunlight became available to indoor gardens, growers have strived to replicate its natural mix of light wavelengths (and to a lesser extent, spectral power distributions).
However, even though a "natural" spectrum is more efficient for healthy plant growth than a more technologically advanced spectrum that relies on a narrow selection of light frequencies, LEDs are catching up fast.
This is good news for fans of electric sky lights, but it is worth considering that many of the "benefits" of LED grow lights are based on the same false assumption that has promoted LEDs for years: the idea that plant growth is fully dependent on the red and blue light wavelengths. Some even claim that full-spectrum LEDs are simply too powerful and can burn plants.
Before we go into the next generation of LED technology, let's make it clear that these LEDs are just as effective at providing a natural-looking light spectrum as older style LEDs, possibly more so.
What's more, they can combine both red and blue LEDs to increase the total amount of light produced, so there's no need to limit your plants to light frequencies that are kickstarted by blue and red light.
This is great news for anyone who's ever been threatened by an LED grower for using sunlight.
Myth: Use Blue Light for Veg, Red Light for Flower
This is a common myth that has no truth behind it. The truth is that blue light is all that is needed for cannabis to grow, flower, and be healthy.
The light spectrum cannabis plants "see" can be explained through the following equation:
Red (645 nm) + Blue (445 nm) = Yellow (595 nm)
All wavelengths in the red and blue regions, such as 625, 640, and 665, are suitable for cannabis growth. No one wavelength works exclusively for veg or flowering. In fact, many LED companies tout that their lights provide the best spectrum for growing cannabis due to equal parts of red and blue. Companies that make this claim are trying to make you believe that their light is superior to competitors.
The truth is that the best LED lights for growing cannabis do not contain any red light at all. There is no value in having a mix of red and blue light because blue is all that is needed. There is no reason to waste electricity and therefore, no reason to feel bad about wasting your time and money on red light.
The Green Sunshine Company’s “Electric Sky” Light
Electric Sky LED lights, a product of The Green Sunshine Company, are an innovative new type of LED grow light that offers the promise of completely red-shifting sunlight. This is accomplished by increasing the amount of blues in the spectrum.
According to its creator, “Electric Sky LEDs are a quantum leap forward in plant growth technology. Incorporating several key features into our light fixture that have been shown to increase growth rates. The result is a highly concentrated photon flux of blue and ultraviolet light of the correct wavelengths, delivered in a process which is both economical and environmentally friendly.”
Since increasing the amount of blue and UV light in the spectrum increases plant growth, it’s a move that seems to make sense. On the surface, therefore, the Electric Sky LED array appears to be a solid investment for indoor growers.
But is it really?
In this article, we’ll take a look at the claim that Electric Sky LEDs produce a spectrum that increased growth rates. We give a summary of the most current LED and HID grow light research and suggest some additions that would make a system like the Electronic Sky LED array more effective. Finally, we provide a few alternative options you might want to consider.
Dual-Way Linear Lenses
The concept of LED lighting is not new, but its application to the marijuana growing industry is. LED lighting is efficient and environmentally friendly. It is ideal because of its ability to mimic the sun's lighting spectrum. LED lights do not produce any heavy metals, heat, or UV radiation so that the health of the plants is never compromised.
High street lighting systems currently dominate the market for grow lamps, due to their cost-effective price, but you will find that LED lighting is a better option. The system of LED lights that is recognized as the next generation of grow technology is called Electric Sky LEDs.
Electric Sky LEDs is a system of patented LED grow lights. The Electric Sky lights are designed to provide your plants with built-in reflectors that provide maximum penetration. These lights also provide a nearly vertical beam of light for maximum yield with minimal waste. The system offers bright, white light in a single package so you don’t need to purchase separate bulbs. Other qualities of the Electric Sky LEDs are that they can be easily mounted and have a long lifespan.
LED grow lights are all the rage these days, and the technology is improving at a rapid pace.
Most lights are marketed as full-spectrum, which means they give off white light and mimic the spectrum of sunlight. However there are new LEDs that break this mold and market themselves as spectrum-based LEDs.
A good analogy to the difference between these two terms could be the difference between a snapshot and a time-lapse. A full-spectrum snapshot shows what happens in a garden at one particular time. These are basic observations about a single moment in time. The time-lapse approach gives a more general sense of development over a period of growth. This information that reveals specifics, but offers more nuance and context. Both of these approaches have value, and finding a balance between the two can be very helpful to growers.
Regular LEDs are designed to provide a snapshot of what plants look like at one specific time and moment in time. The time-lapse approach is more useful for assessing health of your plants, but it's not as good for giving an accurate picture of plant performance at any particular moment in time.
Electric Sky Models Offered
Electric Sky is currently selling two models of LED grow lights. Both models are available in a range of sizes, which range from 1.5″ x 1.5″ to 5″ x 3″. The size of the panels is stated in the model name, and the examples are given in the most common size. For example, the 150W panel is 1.5″ x 1.5″, and the 300W panel is 3″ x 3″.
The first model is the 300W LED, which is 3″ x 3″. It has a 3K or 3,000K (blue/white) chip, and has CREE XT-E LEDs. The second model is the 600W LED, which is 5″ x 3″. It also has a 3K chip, and CREE XT-E LEDs.
Electric Sky ES180
Electric Sky LEDs are an LED grow light manufacturer based in the UK. They provide two LED systems for hydroponic growers: the Electric Sky ES180 and Electric Sky XPLOR 480.
The Electric Sky ES 180 is an LED grow light with three 80 watt diodes. As the name implies, the ES 180 is a 180 watt LED light. The respective wavelength and Kelvin range is full spectrum (50,000k), blues (430-470nm), reds (640-660nm). The diodes are of standard 5-watt LED chips with a very high 90+ percent efficiency.
The Electric Sky XPLOR 480 is a specialty LED grow light with four x 180 watt modules. The ES XPLOR 480 is a set of four bulbs with each bulb consisting of three 80 watt Bosch diodes. In total, the ES XPLOR 480 is a 1,440 watt light. The respective wavelengths and Kelvin range is full spectrum (50,000k), blues (430-470nm), reds (640-660nm). The diodes are of standard 5-watt LED chips with a very high 90+ percent efficiency.
Electric Sky ES300
Electric Sky is a new brand of LEDs, with a couple of old timers behind the company. Matthew Travis and Karl Keary led the original team that pioneered LED grow lights for NASA, before starting LED Worldwide in 1999. Since then, LED brand names have come and gone, but the team at LED Worldwide has continued to experiment and evolve LED technology.
Electric Sky has all of the makings of a truly great LED brand. From the name, to the form factor, to the technology, there should be plenty of excitement building about the Electric Sky brand.
Electric Sky’s product line is basically a mix of a good name and great technology. The name comes from the ionosphere, the layer of the Earth’s atmosphere extending to about 600 miles from the surface of the Earth. The ionosphere is actually the source of atmospheric electricity, and is the layer in which charged particles (ions) of the electromagnetic spectrum are trapped.
The ES300 is a high quality, 315 watt High Efficiency (85-90 CRI), 6 band spectrum, DE & FM, 85-90% efficiency, and a full line of supplemental products.
