Our passive thermal management system is paramount to maintaining the intensity and lifetime of LED lights. In addition to heat management modeling, we make sure that your plants receive the most powerful and uniform light available. Full spectrum allows for better canopy penetration by utilizing green part of the spectrum to facilitate the transport of more well-known photosynthetic receptors in the red and blue range. The BR1.0 Spectrum was also designed with the grower’s vision and plant visibility in mind. A higher Color Rendering Index (CRI) helps the grower see issues at the canopy level with greater clarity than traditional HPS, HID or many LED fixtures.


Grow More & Bloom More with up to 30%-60% Less Electricity

An actual 3rd party grow in Oregon saved 80% in Energy costs. More typical Greenhouse applications with our AC-1 Adaptive controller, (patent pending), yield 40-60% energy savings. Warehouse applications can count on 25% to 40% energy savings, all compared to a 1100W double-ended HPS (High-Pressure Sodium), wall plug to wall plug measurements. When HVAC is included, an additional 20 to 40% energy savings accrue due to much higher LED efficiency and far less heat produced.

Grow-RayTM lights are designed for professional commercial grow applications where production is pushed to the maximum. Bloom-Ray thermal dissipation capability ensures efficient heat transfer from LEDs and drivers avoiding the main cause of LED degradation and failure: heat overload. Our LEDs have a longer life, producing more reliable light intensity and quality over time. Vanishingly low LED failure rates mean higher productivity!

Proven to save up to 80% on an Oregon cannabis grower’s electric bill while providing an extra 15+ % product!

Even more dramatic results were obtained in conventional greenhouse grows of Roses and Yucca.

How does it work?

If the sun is brighter than a predetermined threshold, your Grow-Ray LED lights are turned off. Below this threshold, your lights are turned on in a linear fashion, with just a little for a passing cloud, to full on for a rainy day, or winter weather. This threshold is factory set for 200 to 600 PAR, depending on the plant, or may be user modified or may be user-modified up to 1000 PAR”. .. Our sensors work with our LED lights to provide you with the correct DLI (Daylight Integral) for best growing results.

These sensors are extremely economical, so we attach one per light and then every light has its very own “light meter."  If a particular section of your greenhouse is shaded from the early morning sun, for example, these lights will come on, while the eastern side lighting will already be dimmed or off.

Whatever kind of greenhouse crop you grow, our LS-01 sensor/controller will give you the best results when used with Grow-Ray highintensity LED lights!



Plants can perceive and adapt to their environmental surroundings for optimal growth and development. Illumination is the most powerful environmental stimulus for plant growth and plants have sophisticated sensing systems to monitor light quantity, quality, direction, and duration. Pigments and photoreceptors present on plants are responsible for controlling plant photosynthetic and photomorphogenic processes.

The range of light capable to induce photosynthesis in plants is called “photosynthetically active radiation” (PAR) and it is defined as radiation over the spectral range of 400 to 700nm. Every absorbed photon regardless of its wavelength contributes equally to the photosynthetic process. The range of light capable of inducing photomorphogenic process ranges from 350 –750nm. Photomorphogenic processes play a major role in developmental programs that develop new tissues. The common unit of measurement for PAR is photosynthetic photon flux density (PPFD), measured in units of moles per square meter per second.

The plant’s metabolite production is also influenced by light spectrum. In addition to the primary metabolites of carbohydrates and amino‐acids, secondary metabolites are also influenced by light quality. Many secondary metabolites are key components for plants defensive mechanisms and contributors to odors, tastes and colors. At this point little is known about the manipulation of these secondary metabolites under artificial illumination systems. But what is known is that restricting the light spectrum to a handful of wavelengths can be detrimental for plant development.

Using LED technology allow us to manipulate the light spectrum to trigger potential benefits in indoor production systems. In indoor cultivation systems, it is possible to create a custom designed light spectrum to control plants’ development cycle and enhance biomass production.

Beyond the benefits offered by the LED technology, Grow-RayTM exploits the advantage of LEDs’ controllability. Using a combination of full spectrum emitters along with specially selected monochromatic LEDs, we can control a plant’s developmental pathways stimulating photomorphogenic processes, and at the same time maximize biomass production through the photosynthetic process. As a result, growers will have the benefits of more than 20 years of expertise in indoor plants control systems at the click of a button.


The use of red and blue LEDs has been largely adopted by LED lighting companies as these wavelengths are efficiently absorbed by plants main photosynthetic pigments chlorophyll a and b (Fig A). These companies claim that blue and red LEDs alone are sufficient for horticultural applications, however, in reality, the situation is more complicated. Although chlorophylls are the main pigments found in higher plants, other pigments present on leaves are also capable of absorbing light and in conjunction with chlorophylls, they extend the intact leaf’s absorption spectra that are capable of inducing photosynthesis.

Most importantly, the additional spectrum drives secondary metabolisms necessary for healthy plant development (Fig B). As a result, a wide range of wavelengths can (and should) be absorbed. Unlike pigments extraction solutions, in intact leaves, the “weakly” absorbed green-yellow wavelengths (500—600nm) bounce around the individual cells and are highly reflected by the water-air interfaces increasing their absorption inside the leaves. Furthermore, the higher penetration of green light compared to red and blue lights results in higher photosynthetic activity induced by green light in deeper layers of the leaf. The right balance of light quantity and quality should be achieved to promote the highest energy efficiency while ensuring healthy plant development and maximum biomass production.


In addition to using chlorophyll and carotenoids for photosynthesis, plants use other photopigments for a wide variety of functions. Photomorphogenesis is the process of light‐mediated plant development. Plants can sense light quantity, quality, direction and duration through a variety of photoreceptors which play a major role in developmental processes that generate new tissues (e.g. flowers and leaves). The most important photoreceptors present on higher plants are the Phytochromes, Cryptochromes, and Phototrophins.

The phytochromes respond to the ratio of red (660 – 670nm) and far‐red (725 – 735nm) light. Phytochromes are synthesized in the dark in the Pfr form and following the conversion to the Pfr form, they move to the nucleus. Red light (660 nm) causes conversation of Pfr to biologically active Pfr form and far‐red light (730 nm) the conversation back to Pfr form. Phytochromes influence several aspects of plants development including flowering, seed germination, de‐etiolation, stem elongation, cell expansion, shade avoidance responses, and photoperiodism. Many of these events are related to alterations in plants hormone levels and growth regulators. These changes then cause alterations in plants’ morphology, physiology, development, and metabolism.

The cryptochromes & phototrophins respond mainly to blue light (380 – 470nm). Cryptochromes have a profound effect on seedling
development and flowering. Among several plant growth responses, the most well know parameters influenced by cryptochromes are
de‐etiolation and photoperiodic flowering control. Phototrophins contribute to plant form and function (e.g. chloroplast and leaf movement,
stomatal opening) and unlike the general effects of cryptochromes, the plants’ responses guided by phototrophins are all directly or
indirectly related to optimizing photosynthesis.


The main pigments present at indoor cultivated plants are the chlorophylls and carotenoids. The light energy intercepted by these pigments directly fuels the photosynthetic process of CO2 and water conversion into biomass. To stimulate high biomass production without significantly affecting plants’ photomorphogenesis, light between 500 – 600nm can be used to charge the photosynthetic apparatus without stimulating the photoreceptors controlled by blue, red and far‐red wavelengths.


To achieve maximum biomass production with less energy consumption and ensure healthy plant development, Grow‐ RayTM has designed a
custom light balance taking advantage of the latest LED technology. The specially formulated light balance regulates key plants
developmental process while maximizing photosynthesis. Using specially selected wavelengths at red (660nm), blue (450nm) and far‐red
(730nm) combined with the full spectrum warm white LEDs, our Bloom‐RayTM, Veg‐RayTM and Side‐RayTM can control plant flowering,
photoperiod, leaf expansion, and plant shape while ensuring maximum biomass production.

Blue Light:

The selected blue LEDs present in Grow-RayTM lights affect leaf movement leading to flatter leaves which result in a more efficient surface for light absorption. It also encourages fast leaf expansion resulting in larger surfaces for light absorption and photosynthetic activity. Another very important attribute of the blue is related to the stomatal activity regulation. Stomata are little apertures on the leaf surface which allow for CO2 to move inside the leaf. Higher concentrations of CO2 inside the leaf induce higher rates of carbon fixation and biomass production. The blue light induces stomata opening and allows for higher fluxes of CO2 inside the leaf.

Red Light

The main photosynthetic pigment present in plants, the Chlorophyll a, has its light absorption peak at 660nm (red spectrum). LEDs in this wavelength are also part of the Bloom‐RayTM and Side‐RayTM lights. Using the red LEDs Grow‐RayTM lights provide higher PAR values at lower energy consumption, maximizing the lighting system energy use efficiency. Red light (together with far‐red light) also induces the photoreceptors responsible for flowering and photoperiod regulation, the Phytochromes.


Grow‐RayTM is pioneering the use of Far‐red emitters in commercial LED lights. Bloom‐RayTM lights are equipped with supplemental Far‐red LEDs that in conjunction with the red LEDs provide light at the phytochromes absorption peaks. Controlling the duration and ratio of red/far‐red light makes it possible to control plant behavior to increase biomass production and accelerate plant growth.

  • Day Use Recommendation: The far‐red light provided by Bloom‐RayTM increases photosynthetic efficiency avoiding energy imbalances
    that can occur inside the photosynthetic apparatus under high‐light conditions. It allows the plants to convert more light energy into
    chemical energy which is required for biomass production and plant
  • End of the Day Recommendation: (Research project underway to provide scientific data) Cannabis plants flowering process is
    regulated by a process called the photoperiod. The Cannabis photoperiod requires a minimum of 12 hours of darkness to flower. This
    process is controlled by the phytochrome photoreceptors. Bloom‐RayTM far‐red emitters can be used to manipulate phytochrome
    response and trigger the plants into shorter dark periods and provide additional time for more flowering.


All Grow‐RayTM lights are equipped with white LEDs which deliver full spectrum light to ensure primary and secondary metabolite production. Bloom‐RayTM and Side‐RayTM warm white LEDs are selected to match the required spectrum for optimal plants development at veg and flowering stages. The white lights provide a constant full spectrum light supply allowing for plants’ photomorphogenic processes to be controlled by individual blue, red and far‐red emitter manipulation without compromising plants’ photosynthetic activity. It ensures the required light flux to maintain optimum light energy conversion throughout the entire plant growth cycle.

  • Far‐Red Spectrum: The warm white LEDs used by Bloom‐RayTM lights ensure the delivery of a small amount of far‐ red radiation
    which is important to ensure healthy plants development and allows for phytochrome control using different ratios of simultaneous
    irradiation of red and far-red.
  • Green Spectrum: The amount of green light flux generated by the white LEDs used in Bloom‐Ray not only increases photosynthetic
    efficiency by deeper light penetration into the canopy and individual leaves but is also useful in manipulating plants traits as they
    counterbalance the effects of blue‐light induced cryptochromes while not affecting blue‐light generated flux through phototrophins.
  • Badge
    Blue Spectrum: The different amounts of blue light emitted by warm‐white LEDs (Bloom‐RayTM) is carefully calculated to provide the
    right balance between wavelengths supplemented by the blue and red LEDs to induce specific desired plant responses at the different
    developmental stages.
