The Modern Phosphor Breakthrough

Old narrowband LED technology only performs in a small range of red and blue colors. The rest of the spectrum – like green, yellow, and infrared – can’t be produced efficiently. Additionally, this old LED technology is sensitive to heat, requiring large heatsinks and noisy fans.

The phosphor LED is the reason why white replacement LED bulbs for the home have exploded in popularity. The technology has advanced to efficiently produce colors up through far and infra red, creating an amazing opportunity for indoor growers. Phosphor-coated LEDs emit a rainbow of light in a specific shape and range of color.

The catch with phosphor LEDs is that most of them are white, and they are designed to be bright for human eyes.  LED chip manufacturers – the companies that make the actual dots that create light – market their LEDs in terms of how they look to the human eye, by “Kelvin” which is why you see things like 6500K and 3000K.  Neither is meant for plants, but that’s just what we growers have to work with…

There is an art to combining these LEDs into specific combinations that lead to a wideband spectrum designed for plants.  This is what our first, patent-pending spectrum, “Green Sunshine One” accomplishes…

 

The “GS1” Spectrum for Flowering Plants

Our first spectrum, the Green Sunshine One (GS1) is designed to meet the needs of flowering plants by encouraging large plant development throughout the vegetative and flowering stages of growth.

This spectrum is filled with leaf-penetrating colors.  This means plants will fully develop beneath the canopy and behave as they do in natural sunlight with enhanced green, yellow, and far-red light.

Common Purple or White LED systems emit inefficient colors for plant growth because they leave out important colors for plant growth.

When colors are left out of a spectrum, it requires 25-100% more light intensity to match the efficiency of a traditional bulb system, since all bulbs are wideband.  Spectra containing similar characteristics as the GS1 spectrum have been scientifically proven to match or exceed the HPS in growth performance.

This means that unlike common purple and white LED systems, the GS1 spectrum can achieve similar results as the HPS at the same light intensity.  White or Purple LED spectrums require higher light output for comparable results.  High light levels cause plant stress and light burn — the opposite of what we want out of a grow light.

Experienced and beginning growers will appreciate a plant’s natural response to the GS1 spectrum.  Grow with the piece of mind that your plants are receiving all of the light they need in the correct ratio for maximum harvests in flower.  Your plants will thrive.

No other LED grow light  offers a purpose-built spectrum with continuous wavelength output through infrared (780nm).  The color ratios contained in the GS1 spectrum are the secret to unlocking massive yields that keep up with and can exceed the efficiency of the High-Pressure Sodium spectrum.
