Demystifying “Magic Spectrum” Formulas.

.
Red/Blue vs. Full Spectrum: Magenta no more!

The cannabinoid content of cannabis is primarily determined by strain, however environmental factors such as light also play a significant role.
.
Bluetech grow light fixtures have been shown, through tests performed by the University of Toronto Institute for Optical Sciences laboratory, to deliver superior quality and ultra-high intensity outputs.  The results of the tests showed that our luminaries exceed traditional high-power, best-in-class high pressure sodium (HPS), metal halide (MH), and fluorescent lights in terms of both light output and output quality.

Additional recent tests conducted by the same laboratory confirm Bluetech has achieved an efficiency of 28 percent,1.7 times that of leading 1000-watt double- and single-ended high pressure sodium (HPS) fixtures.

These are the parameters of Bluetech light fixtures that contribute to increasing grower’s revenues by expediting the growth cycle and producing a plant wit greater flower dry weight and higher concentrations of THC, CBD, THCV and CBG.

 

|| The truth about green light and why it is essential

Previously, 660nm (red) and 450nm (blue) were the most energy-efficient LED packages, and coincided with peak channel A and channel B absorption areas.  While effective, it led to a negligence of key photo-receptors and pigments outside this range.

No more Red-Blue-Magenta

Most recent research on plant lighting discourages the idea that plants only needed two individual spectra for optimal growth.

. 

 

|| Recent research has shown that green light promotes photosynthesis in plants, finding that green light is able to penetrate deeper into leaf surfaces to drive photosynthesis in chloroplasts located towards the bottom surface of the leaf.

Left: Narrowband red/blue LED Right: Polychromatic Broadband Light

 

As photosynthetic photon flux density (PPFD) increases, light energy that is absorbed in the upper chloroplasts tends to be dissipated as heat,

while penetrating green light increases photosynthesis by exciting chloroplasts located deep in the inner tissues (parenchyma) of a leaf.  (Terashima et. al., 2009).

.
.

|| Additionally, green light penetrates through leaf surfaces much better than red or blue light to reach the lower canopy, which is extremely important in the dense canopy (S.O.G.) production techniques that are common in controlled environment agriculture.

.

No “Magic Spectrum” for plant growth exists. The truth lies in physics.

There is no “secret magical spectrum” that is going to allow a 100W red-blue fixture to replace a 1000W fixture because it only uses the “wavelengths that plants need.”

Be cautious of a company that spends too much time talking about their “special recipe” or “patented” spectrum.  Especially if they do not expend equal effort in publishing their product efficacy and delivered PAR measurements.

 

|| On the other end, manufacturers that try to “mimic sunlight” like to use different variations of .“…our LED grow lights behave more like the sun as it marches across the sky…”
.

Such poetic statements are often used as a justification for overpriced products, rather than demonstrating qualities that truly contribute to increasing a grower’s revenues and profits.

There is a short list of companies which manufacture industrial-grade LED fixtures for the professional horticulture industry, and none of them try to “mimic sunlight”, replicate HPS or metal halide spectrums, or market the number of LED “bands” in their fixture.
.
They focus on and market the real, meaningful specifications of their fixtures.

FCCI – Bluetech Full-Cycle Cannabis Spectrum for Indoor 

Green light is a vital part of Blue Tech’s polychromatic broad-band full-cycle spectrum.  Cannabis indoor (FCCI) is optimized for full-cycle plant cultivation, precipitated growth and thorough plant development in indoor production environments.   

Green light  penetrates further into the leaf through Cuticle and Epidermis. This penetration increases overall photosynthesis compared to purple or pink spectrum LED lights, or HPS lamps. 

 

|| The fullness of the FCCI spectrum is tailored for growing plants from propagation to senescence (germination, clones/cuttings, mothers, vegetative, and flowering applications) in indoor environments. 

Our customers have chosen this specific spectrum as it was scientifically optimized for rapid growth and complete plant development.

EBCI – Bluetech Extra-Bloom Cannabis Spectrum for Indoor

Green light is also vital part of Blue Tech’s extra-bloom spectrum.  Extra Bloom Cannabis indoor (EBCI) spectrum is used in single-purpose flowering rooms where it boosts flowering by adding more energy in the 660nm (deep red) range.

BEGH – Bluetech Spectrum for Greenhouse

Available in Winter 2018 in a new IP67 model, Bluetech’s spectrum for greenhouse (BEGH) will add more energy in the 400-500nm (royal blue) ranges which are used to eliminate tall plant stretch induced by the Sun’s far red radiation.
