Penetrator Grow LEDs DOUBLE Your Quality
If you could have quality or quantity which would you choose? Thankfully with Hydro Grow you get both! Our Penetrator LED grow lights don't just deliver the highest yield per watt of any grow light, but are also lab-proven to improve the quality of your harvest.
In 2014 Botanical Solutions (a commercial marijuana farmer in WA state) bought our 336X-PRO (now 336XL) lights to test the yield and quality differences compared to their HPS lights. Here is what they had to say:
"We had our Cherry Harlequin flowers tested that were grown with the HydroGrow LEDs we purchased. The THC & CBD cannabinoids doubled!
I have been growing our CH/HQ for 2 years with HPS lights. The tests were consistently: THC 3-4% CBD 7-8% (approximately 2:1 CBD - THC ratio).
When I had the flowers under your LEDs tested, we got amazing results:
7.4%CBD & 14.8%THC! Almost Doubling the cannabinoids!"< Collapse
It’s one thing to claim you’re the best. It’s an entirely different thing when your grow lights broke the world record for the highest yield ever achieved on a single autoflowering cannabis plant. TWICE. Are you ready to be the next person to break that record?Learn More>
Break Records with Penetrator LED Lights
Imagine you are betting on a race between an Olympic World Record Holder and your local high school track athlete. Who would you choose?
The smart person is going to put money on the World Record holder. The risky person who likes a big gamble will bet on the track athlete. So when it comes to betting on whether a competitor can beat our long-standing world-records, why would you consider anyone other than Hydro Grow?
At the end of the day buyers want to feel confident you're purchasing the absolute best grow light with your hard-earned money. You don't have a safer bet than putting your money on a world-record holder (especially since you have a 90 day trial and a Performance Guarantee). The Hydro Grow 336XL set two consecutive records in 2011 and again in 2012 for the highest yield ever achieved on a single autoflower cannabis plant. Our record still stands to this day, so don't make the mistake of betting on our track athlete competitors, when we're the world champs.< Collapse
Independently proven to yield 3X more per watt compared to competing LED lights from Advanced LED, Haight Solid State and more! No competitor gives you more proof they make the best grow lights on earth.Learn More>
A High School teacher was supplied test lights from Hydro Grow and Advanced LED for the purpose of a side-by-side grow test to prove who had superior technology.
Both lights use secondary lensing technology originally introduced by Hydro Grow. The Advanced Diamond Series 300W fixture used a 12-band spectrum and 3W LEDs. The Hydro Grow 336X fixture used a 6-band spectrum and 1W LEDs.
At the end of the test the Hydro Grow plant produced 12.2lbs of beefsteak tomatoes (and was still producing new fruit/flowers). Advanced LED by comparison produced only 3.68lbs of tomatoes and the plant had ceased producing new flowers/fruit at the end of the 78-day test.
The Hydro Grow 336X delivered 3.3X the yield of the Diamond Series 300W from Advanced LED! Proving that our products deliver 3X more yield than competing LEDs!Watch The Video!
Independent tests confirm our latest Penetrator LEDs deliver 4X the Yield of High Pressure Sodium (HPS). The LED vs HPS debate is OVER. No grow light gives you more yield or higher profitability than Hydro Grow.Learn More>
Cannabis Training University with more than 1 million followers on social media, wanted to see if LEDs could truly compete with HPS in the flowering stage.
Two 336X-PRO units (now 336XL) were tested against a dual-bulb, 1200W HPS light. 4 plants (clones from the same mother) were put under each set of lights; 2 per LED and 4 under HPS. The LED group was run at partial intensity during veg and full intensity during bloom.
The LED group grew faster, while producing more head colas and larger buds over the same time period as HPS. At the end of the test the yield from the two largest plants in each group were compared.
The 336X-PRO (500W) delivered 1.5X the yield of the plants grown under 1200W of HPS. This equated to 4X the grams per watt! For commercial growers this means 4x more profits by switching to Hydro Grow LED.Watch The Time-Lapse Video!
Founded in 2008 by medical marijuana dispensary growers, Hydro Grow LED lights have always been engineered with the end user in mind. Being growers themselves, every last detail has been carefully optimized to give you the fastest growth and highest quality in the least time.Learn More>
LED Growing Lights Designed by Growers for Growers
Hydro Grow was founded in 2008 by two dispensary owners/growers from WA state, who sought a more efficient method for producing high quality plants indoors.
Careful testing with significant R&D efforts on medical cannabis plants, allowed these two geniuses to build a grow light that eclipsed the mighty HPS not only in yield, but also quality.
Their amazing technological advancements lead to the modern day LED Grow Light; however our product remains undefeated to this day when compared side-by-side against any competitor. A true testament to the engineering marvel that is Hydro Grow.< Collapse
Perfection takes time to achieve. Our current G4 LED grow spectrum is the most advanced and powerful in the industry. Take a look at how we went from prototyping to G1 and beyond.Learn More>
Creating the Perfect LED Grow Spectrum
In 2008 when our development process began, the most complex LED grow lights used only 3 wavelengths (one red, one blue, one white). To our engineers this made little sense as the science of photosynthesis states you need 2 red and 2 blue to stimulate both types of Chlorophyll.
We then created the world's first 5-band LED grow light: a 90W "UFO" with 2 reds, 2 blues, 612nm orange. The test results were dismal. The 612nm orange was causing negative growth characteristics, so it was replaced with full spectrum white and joined with 730nm far-red to make the world's first 6-band spectrum. The ratios were then re-calibrated and the testing against HPS was incredible. The Hydro Grow G1 spectrum was born, and the first in the world to use far-red.< Collapse
Advanced optics (lenses) have always been at the core of Hydro Grow technology. The name Penetrator originated from developing the world’s first 60° lens, which gave our first LED lights the highest penetration in the industry.Learn More>
Earning the Penetrator LED Name
The UFO prototype from 2008 used the same 120° lenses as everyone else at the time. Not only did this cause the 90W prototype to cover more than a 5' x 5' area (less than 3.6W/ft²), but the PAR numbers faded very fast over vertical distance, allowing only short plants to be grown.
The next prototype was a 120W rectangular fixture with our G1 spectrum and newly developed 60° lens (the first in the world for grow lights). The goal was to increase light penetration (intensity over vertical distance) so taller plants could be grown. The growth results for lettuce and tomatoes were incredible compared to HPS; however the coverage area had been reduced to an unreasonably small space. Our development was not yet finished.< Collapse
Our 120W prototype was loaded with LEDs from one side to the other as shown above. After solving the spectrum and penetration equations, it was evident the LEDs would need to be spaced further apart to get more coverage. 21 LEDs were the minimum required to create our complex spectral ratios, which gave birth to the Hydro Grow light engine.
Light engines were distributed on larger circuit boards to create larger coverage areas with a more uniform intensity. At that point our "Penetrator™" series was born, and began taking down one competitor after another via independent grow tests. But we weren't even close to done developing our technology. We had only just begun.
Claims are easy to make, but few back them up with proof in the form of data. Hydro Grow’s latest X3 lens technology delivers over 3X the PAR output and Penetration of competing LEDs from companies like Lumigrow, Fluence, BlackDog, Spydr, Illumitex, Philips and more.Learn More>
3X More PAR than Competing LED Grow Lights
At Hydro Grow our best is never good enough, so we are constantly researching & developing behind the scenes to bring you a better grow light.
While our original 60° lens was an engineering marvel, it pales in comparison to our exclusive X-Lens™. Most competing LED grow lights use a standard 90° lens on their LEDs; however Hydro Grow uses our own patent-pending X-Lens technology.
The PAR charts to the right compare our 21-LED light engine with and without our X-lens. The readings were recorded every 6" on a 2' x 2' grid at a hanging height of 12".
Compared to a standard lens (still used by competitors like LumiGrow, Fluence, BlackDog, Spydr, Illumitex, Philips, Etc...) our X-lens delivers nearly 4X the PAR output and penetration!< Collapse
Compared to major competitors like Lumigrow or DormGrow, Penetrator LED grow lights deliver up to 65% more usable coverage area (per watt) to grow your precious plants.Learn More>
Double Your LED Coverage Area
For years Hydro Grow has been working to bridge the gap between LED and HID on coverage. With each new generation the gap gets smaller.
Coverage area isn't just about how much area your light reaches. It's about how much area is has enough intensity to actually grow plants. The easiest way to judge this is by averaging out the PAR values of any given area. The higher the average, the "bigger" the coverage area.
The lights compared on the left were all tested in our light-sealed lab using the same PAR meter, over the same 4' x 4' test grid. The Hydro Grow 168XL (300W) had the highest PAR average across the board.
As the distance from the source increased, so too did the growing disparity between competitors. At 12" Lumigrow had only 18-25% lower coverage averages compared to Hydro Grow, but at just 24" they dropped to as much as 43% lower! By comparison DormGrow was up to 65% lower compared to Hydro Grow at 24"! Plenty of competitors claim to be the best, but only Hydro Grow backs up our claims with real proof in the form of data.< Collapse
Compared to the same µmol intensity of full-spectrum white light from CFL or HID, our G4 spectrum Is independently proven to grow plants up to twice as fast.Learn More>
DOUBLE Your Growth Rate
Back in 2010 Hydro Grow partnered with a leading PhD at the University of WA to work on spectral development. She opened our eyes to the important role green plays in the quantum yield of plants, expanding our knowledge beyond photosynthesis.
The University of WA ran several tests in a controlled growth chamber, comparing the power of Hydro Grow's G2 spectrum to competing lighting technologies (HID & CFL). To ensure the changes in growth were solely related to spectrum, the PAR output from each fixture was set to 300-400 µmol above test groups.
The LED test group at UW grew lettuce approximately 40% faster with our G1 spectrum. The test was later repeated by the SuperGrow company (a commercial producer of lettuce/herbs) with our G4 spectrum. Samples from their test group are shown to the right, where the LED plants grew twice the size in the same period of time, increasing their productivity and yield two-fold!< Collapse
Commercial greenhouse testing proves that our LEDs provide comparable growth using over 50% less watts than HPS grow lights. Say goodbye to all those expensive electric bills.Learn More>
X3 LED Grow Lights Cut Your Electric Bill in HALF
Swift Greenhouses is one of the largest producers in the country of starter plants for other greenhouses/nurseries. In 2015 they ran a commercial case study comparing different wattage Hydro Grow fixtures in their greenhouses, to their 400W HPS lights.
The actual wattage draw of their HPS lights was 470W, accounting for ballast inefficiency. They then compared this to the SOL 200W and 300W models, which have approximately 1/2 the PAR per watt of our X3 grow lights.
The test concluded that on most plant varities (over a dozen were tested), the LED test groups provided comparable results, and on several varieties (like Lavandula Angustifolia Hidcote shown on the left) better results. Faster growth rates and better rooting in the plug and cutting industry makes a huge difference on both productivity and profits. Especially when it's costing you 40-60% less for lighting!See the Swift Greenhouse Case Study
No two gardens are exactly alike, which is why Hydro Grow invented the bracket system to give you total control. No matter if you’re using a SOG, ScrOG or LST method, our lights can be adjusted so they are always the BEST LED grow light for your garden.Learn More>
The BEST LED Grow Light for Your Garden
Gardens come in all shapes and sizes, and yet our competitors use a "one size fits all" approach to offering you a LED solution. Hydro Grow was the first company in the world to put High Power LED Grow Lights on an adjustable bracket system to enhance the user's experience.
Our 336XL is the most versatile grow light on planet earth, offering 10 standard adjustment configurations from the highest penetration to the widest and most even coverage. So whether you're a MAX yield grower, like to ScrOG or just need more light to the edges of your space, no one gives you a more customizable grow light.< Collapse
Photosynthetic Active Radiation (PAR) readings tell you how powerful a grow light is for growing plants. Hydro Grow LED lights have the highest PAR output per watt in the entire industry.Learn More>
Grow Light Energy is Measured in PAR
PAR is the region of light from 400nm - 700nm that plants utilize for photosynthesis (growth).
PAR is measured with a device called a quantum light meter. This device tells you the photon flux density (aka PPFD) measured in micromoles (µmol/m2/sec) per meter squared per second.
The graph to the right shows the relative sensitivity of different colors of light to a quantum light meter. Blue LEDs have the highest PAR output per watt, reds are next and greens/yellows are last. This means it's more difficult to create high PAR values with green or yellow light than it is with red or blue.< Collapse
Light is not created equal. Hydro Grow uses wavelengths with the highest photosynthetic conversion efficiency at 440, 470, 640 and 660nm. This guarantees the highest conversion from watts of light into plant growing energy.Learn More>
Maximum Photosynthetic Efficiency
Photosynthesis is the process of converting light, CO2, water and nutrients into carbohydrates to fuel plant growth. It is driven by two primary compounds within the leaf known as Chlorophyll A & B, and to a lesser extent carotenoids (about 10%).
Chlorophyll A & B are very sensitive to certain colors within the PAR range and not others. Example: 470nm (blue) is aborbed at approximately 80% efficiency, whereas 610nm (orange) is absorbed at less than 20%! So Just because a light has a high PAR value, does not always mean it is more powerful than another.
The wavelengths absorbed with the highest efficiency are found at 439nm, 469nm, 525nm, 642nm, 667nm and 740nm.< Collapse
Hydro Grow’s G4 spectrum penetrates deeper than any other thanks to green light. Green light helps blue and red penetrate deeper into plant tissues, resulting in the highest photosynthetic growth rates.Learn More>
Maximum Penetration & Absorption with Green LEDs
It is a common misconception that plants primarily reflect green light. According to a study from Oxford, green light drives photosynthesis more efficiently than red light in the presence of strong white light. This is in part due to the fact that green light penetrates deeper through leaves than red or blue, acting as a "penetrant".
Hydro Grow uses a carefully balanced spectrum of red, green and blue light, that when blended together make strong white light. We were the first company to incorporate green LEDs into grow lights, which speeds up the overall rate of photosynthesis, allows our spectrum to penetrate deeper into your leaves than competitors (for better absorption), and allows red and blue light to be absorbed more efficiently.< Collapse
Hydro Grow supercharges growth rates by 30%, by using more 740nm far red than any competitor. This wavelength when combined with 660nm deep red increases photosynthetic growth by an incredible 30%!Learn More>
Supercharged LED Growth Rates
In 1957 a scientist named Robert Emerson discovered that when far red light (700-750nm) was shown with deep red light (660-680nm), the rate of photosynthesis increased by a whopping 30%!
Not only was Hydro Grow the first to use far red 740nm in 2008, but we use a higher percentage than any other manufacturer! 740nm is the most expensive color to purchase for grow lights, which is why most competitors give you 1 or 2 LEDs per light. Hydro Grow gives you two per light engine! We spare no expense making sure you get the full benefits of Emerson's research by increasing your photosynthetic rates by 30%!< Collapse
While UV light in the 285-315nm range has been shown to mildly increase THC in cannabis, there aren’t any LED grow lights using this range of UV. Instead they use alternate 365nm+ wavelengths, which thicken leaves and reduces photosynthetic rates.Learn More>
Don’t Stunt Your Growth with UV LEDs
There is an over-abundance of mismarketing in the LED industry about UV light. While it is true that UVB (285-315nm specifically) can mildly increase resin and THC production in cannabis, the simple fact is that LEDs in this range cost more than $100 per watt! They are also far weaker than cheap reptile bulbs you can buy from the pet store.
Our competitors try to lure in the uneducated consumer by hyping their use of "UV" in their products. None are using a UV LED in a wavelength that will benefit your plants as described above. 740nm acts similar to UVB in its ability to increase resin and THC production, without the undesirable side effects. It's how our spectrum was able to double the THC and CBDs in the Botanical Solutions case study.
If you still wish to use UVB for supplemental purposes, we recommend purchasing a cheap T5 version from a pet store. Just be careful not to overdo it, as UVB can also stunt photosynthetic rates and reduce overall yield!< Collapse
The Hydro Grow G4 6-band LED spectrum is so powerful, it creates 3X the average par per watt of full-spectrum white LEDs. Don’t be fooled by any competitor who uses a large quantity of white LEDs in their grow lights.Learn More>
3X The PAR Per Watt of White LEDs
Hydro Grow was the first in the world to create a "full spectrum white" LED grow light using RGB LEDs instead of white LEDs. The result is 3X higher PAR output per watt and the ability to fine tune the ratios of red, green and blue light. It also allows for deeper light penetration and better absorption of our blue and red wavelengths.
The image to the right is a PAR/spectrum test ran on a Light Engine filled with 2700K white LEDs, against our G4 Light Engine. Beware of any LED light using white LEDs instead of colored ones, as test data proves they are at least 3X less powerful in PAR output alone.
In the world of spectrum, less is more. As we learned above, colors that are inefficiently absorbed by plants (like 610nm, or white LEDs) have no place in a grow light. Yet this doesn't stop many of our competitors from loading up on them with 9, 11, 13 or even 15 wavelengths!
Hydro Grow lights use the 6 wavelengths most efiiciently absorbed by plants (440nm, 470nm, 525nm, 640nm, 660nm & 740nm). This gives our lights the highest conversion rate from electrical energy (watts) to plant growing energy. It's one of the many reasons our lights are still undefeated after a decade of independent testing.< Collapse
Contrary to popular belief, plants grow slower and produce smaller yields when they are given a different spectrum in veg vs bloom. Don’t make the mistake of buying a “veg” light from our competitors. It will be missing many vital wavelengths plants need to grow.Learn More>
The Veg vs Flower Spectrum Myth
There is a common misconception that blue-dominant lights are for vegetative growth and red-dominant lights are for flowering. This myth came about due to limitations in technology 50 years ago when indoor growing began. At that time the primary options to growers were Metal Halide (blue-dominant) or High Pressure Sodium (red-dominant) bulbs.
Growers noticed that the MH caused shorter, stockier plants while HPS caused stretching. What most failed to realize is that these growth characteristics are morphological stress responses of the plant due to not receiving a properly balanced spectrum. Stress responses limit both growth rate and yield. For this reason some growers used MH and HPS lights together to promote a more complete spectrum, while others used MH for veg and HPS for flowering.
With the creation of LED Grow Lights the outdated method of stressing plants to create desired growth characteristics became obsolete. And yet some of our competitors are still trying to market blue-dominant LED lights for veg. It shows how little our competitors know about the science of plant growth.< Collapse
Hydro Grow’s G4 spectral ratios has been proven by NASA to grow plants up to 25% faster with up to DOUBLE the yield per plant compared to alternate spectral ratios used by our competitors.Learn More>
NASA Proven: 30% Faster Growth with DOUBLE the Yield
The ratio of blue to green to red light is vitally important to your plants. The higher the absorptive efficiency of a wavelength, the faster a plant saturates on that color. Excess blue will stunt plant growth. Excess red will cause unwanted stretching. For this reason a grow light must be calibrated perfectly with red, green and blue light to achieve the fastest growth and highest yields.
Plants have evolved under the sun, to grow with a set spectrum year-round. Testing done by NASA also proves that plants grow faster and yield more, when they are given a single set spectrum throughout all stages of growth (veg and bloom).
Hydro Grow lights are quantum-balanced at 10% blue, 15% green and 75% red. NASA Testing on Starfire Tomatoes proves these ratios finish tomatoes up to 25% faster (100 days vs 130), with up to double the yield (185g vs 92.5g) compared to alternate RGB ratios. In summary you get a higher daily yield per plant 25% faster than competing lights, increasing your productivity substantially. This is yet another reason why Hydro Grow lights are still undefeated after nearly a decade. No one knows the science like we do.< Collapse
NASA testing on Spectral Variance with Starfire Tomatoes
Hydro Grow lights are calibrated so they deliver the optimal light intensity for your most demanding plants. This prevents damage to chloroplasts that can happen when too much intensity is given, resulting in lower photosynthetic rates or even death.Learn More>
What is Light Saturation?
The sun delivers approximately 2000µmol of full spectrum white light at sea level on a bright sunny day; however plants are limited in the amount of light they can absorb.
Think of each µmol of light (a photon) as a grain of sugar and the absorptive capacity of a plant like water. Once water is saturated, sugar no longer dissolves but instead collects at the bottom. The same is true of plants. The amount of light any plant can absorb is based on it's type. Shade plants need very little light, and fruiting plants need a lot.
Despite the idea that "more is better", any light given above the saturation point of a plant is not absorbed, and thus is wasted energy. Excess PAR intensity can also stunt or even kill sensitive plants like orchids. So beware of any lights advertising PAR values above 1500 µmol, as no plant can utilize this much energy and it could do more harm than good.< Collapse
Hydro Grow provides more PAR data on our fixtures than any competitor to make YOU a stronger grower. By learning how to read out PAR charts you can maximize the potential of our LED grow lights for your indoor garden.Learn More>
Making Your Garden Stronger with PAR Data
In 2009 Hydro Grow created the world’s first PAR charts for grow lights. Since then PAR output charts have become the industry standard for gauging the potential of a grow light. Now in 2018 we are introducing an entirely new type of chart, designed to make understanding PAR easier.
To create each chart a light is hung directly in the center of a 4’ x 4’ grid in a completely dark, light-sealed room. The grid is marked every 6” away from the center point and a PAR reading is taken on the intersection of the grid lines (shown as circles on the grid below). The readings are then recorded into an Excel spreadsheet and color formatted based on the intensity of each reading. The darker the color, the higher the PAR output.
Unlike our competitors, Hydro Grow has multiple PAR data sets at 12”, 24”, 36” and 48” hanging heights for each light (other than single bars like the 84X-PRO). This is because our SS (solid state) series utilizes a bracket system that allows you to customize the output to your liking. Whether you position the light bars inward, outward, or tilt them inward or outward, we have output graphs for each configuration. No one gives you more versatility for your indoor garden or data to make you successful, than Hydro Grow.< Collapse
As light travels away from a light source it loses intensity. Hydro Grow LED lights are able to maintain higher intensity levels over distance (penetration) thanks to our advanced X3 lensing technology.Learn More>
Understanding LED Light Dispersion
The laws of physics state: “the intensity of a source is inversely proportional to the square of the distance from the source.” This means that as you move away from the source, PAR intensity decreases.
Example: at 2’ away a light has 1/4 the intensity, and at 3’ has 1/9 the intensity of the total intensity at 1’ from the source. Intensity decreases because light is dispersed over a larger area the further you move from the source. Because our LEDs are a directional source (not a 360° bulb like HID) and have the concentrating power of the X3 lens, the intensity (penetration) holds better over distance than HID, T5, Sulfur Plasma or Induction.
The height at which your lights are hung affects the PAR intensity, dispersion and blending of light between fixtures. The spacing between fixtures will likewise affect these values.< Collapse
The graphs above provide a visual representation of how PAR dispersion and intensity change with vertical distance from the source. Each graph represents a 48” x 48” area with the 336XL light hung directly in the center. The graphs below provide a visual representation of how PAR blends between two 336XL fixtures spaced at various distances center to center.
Dense Layouts provide the highest overall PAR intensity and the smallest overall coverage area.
Optimal Layouts provide the best blend of intensity, coverage area and PAR uniformity.
Thin Layouts provide the highest overall coverage with the largest variance in PAR values between lights.
