OUR SCIENCE
At GLS, we tailor our LED grow light wavelengths for particular photomorphogenic responses, photoperiodic signals, chlorophyll A and B absorption, xanthophyll carotenoid pigments, and anthocyanin accumulation in plant tissue. We also design and build our LED modules using a precise mix of light emitting diodes including Samsung white LEDs and OSRAM 660 nm red LEDs. The white portion of the recipe is composed of a precise ratio of warmer and cooler correlated color temperature (CCT) LEDs. The result is our GLS HI RED spectrum--exceptional for full-cycle cannabis cultivation.
OUR MISSION
-
Delivering the highest quality, plant-loving light to your crops is one of our two primary aims at Grow Light Science. We never skimp on PPF (photosynthetic photon flux).
-
Our second aim is to offer lower LED fixture cost.
Our strategy is to give your plants what they need to flourish while giving you what you need most--exceptional ROI and more money in your pocket.
GET MORE PHOTON FLUX FOR YOUR BUCKS
When you invest in a grow light, you want light output that is going to make your plants thrive . In scientific terms, you want an appropriate level of photosynthetic photon flux (PPF)--the portion of emitted photons that your plants care about--with an optimum spectral distribution (mix of wavelengths) to drive photosynthesis and support cannabinoid and terpene development. You invest in PPF upfront when you buy your lights and every month thereafter when you pay the electric bill. At Grow Light Science, our approach is to offer the best spectral distribution of PPF on the market at the lowest cost. In the broader lighting market, the expression is "most flux per buck". When compared with many of the best-selling LED lights on the market today, Grow Light Science comes out on top in most key metrics including efficacy, fixture price/PPF, fixture price/watt, and annual electric cost.
Have a look at the table below. It compares our GROW 300 and GROW 200 models and our new PROGROW 850 to all of the competetive LED grow lights tested by Shane at MIGRO.
The bottom line is that Grow Light Science grow lights deliver more flux per buck--a lower cost per unit of light output--and a dramatically better return on your investment.
We encourage you to compare our products to any and all competitor's grow lights...if you can find a better light, buy it.
At Grow Light Science, we combine the highest quality LED recipe with smarter fixture chassis design and manufacturing methods to deliver the best value in the grow light industry today. You'll get a lot more high-quality light for your money from Grow Light Science.
