Super Grow LED Lighting vs. HPS
Based upon low entry cost and the fact that they perform well, High Intensity Discharge (HID), and more specifically, High Pressure Sodium (HPS) lights have long been used as indoor grow lights, particularly for the late vegetative and flowering/fruiting stages of growth.
Despite high operating costs and frequent bulb replacements, viable alternatives to this ageing technology have yet to win over the grow light market, until now. Crop yield (as measured in Watts consumed per gram of dried product) is of primary consideration and is the common industry-accepted metric.
Twice the grams per Watt compared to HPS
Using dried chilies as a reference, indoor growers using HPS lights generally achieve 0.5 grams per Watt at harvest time, based upon a one pound yield (453 grams) and using a 1000 Watt HPS lamp. There are some claims of up to two pounds (900+ grams) of dried product, but one pound per 1000W is the generally accepted claim. Also, please note that a 1000W HPS light actually consumes 1085-1150 Watts, due to ballast inefficiencies.
Our LED grow lights: the smaller SGL6 at 25 Watts and the larger SK450 at 250 Watts will produce from 1 gram per Watt to 1.5 grams per Watt depending on the growers experience and setup. One SK450 LED grow light can easily achieve 250 grams, with more experienced growers obtaining 300 to 375 grams or more dried product.
LED grow lights today
LED grow lights, although relatively new to the grower’s marketplace, have been in use for many years in venues no less exacting and prestigious than NASA. Their high efficacy (lumens per watt), spectrum accuracy (in terms of color) and well-aimed output make them ideal for growing plants in almost any environment, including for space travel.
There have been several problems keeping the marketplace from wholly embracing LED grow lights, not the least of which is a slew of absolutely useless LED grow light products, in terms of growing efficiencies. In addition, these sub-standard products have been extremely costly in comparison to more efficient “traditional” lighting technologies, so costly that a return on investment is never realized within the lifespan of the LED grow light.
The result is a sour taste in the mouths of those more progressive growers that are willing to take a chance on new products and technology. Of course, bad news travels quickly and once it’s made it to the Internet, it usually snowballs and becomes the de facto truth.
It is our mission to turn around the negativities towards LED grow lights by addressing the problems plaguing this technology and the solid state grow light market.
The engineering staff with Super Grow LED lighting has been designing solid state (LED) frequency-specific lighting for over a decade, creating solutions for everything between light pollution abatement for large optical telescopes, for turtle sanctuary illumination, and for effective grow light technology. We have been testing LEDs for use in grow lighting in our labs for over 9 of those years and up until now, have refused to enter the market without a clearly effective solution, in terms of both cost and performance. The wait is over.
Super Grow has developed and manufactured an affordable product that regularly yields twice that of traditional lighting methods. We are quite happy to say that routine yields using Super Grow LED lighting is more than 1 gram per Watt, even for the most novice of growers, following directions for use supplied by Super Grow.
Super Grow LED engineering
The Super Grow LED grow light is a professionally built piece of equipment, not a light bulb or cheap gimmick. Our product is driven by real customer requirements and is built with an emphasis on performance, durability and longevity.
Commercial-grade, fan-less construction
Optical-grade, UV-stabilized lenses completely collect and focus light on your plants with nothing wasted
Professional thermal engineering to extend LED and power supply life;
Chassis is aluminum and non-conductive hard-coat black anodized
3 Watt LEDs driven at just 1.66 Watts so they do not burn out
Our lighting solution is comprehensive for any budget, crop or grow area.
Full spectrum design
Super Grow LED lighting accommodates plants indigenous to any latitude. All that means is that our LED grows anything, as we cover the entire visible lighting spectrum, and more.
Plant needs vs. LED output
It’s known that plants at different latitudes trigger photosynthesis at slightly different frequencies due to the conditions in their respective environments. Most HPS products provide light in semi-discrete bandwidth, meaning, the output provides light in fairly specific frequency bands and almost none in others. Depending upon the origin of the plant and the type of lamp used, the plant’s lighting needs may or may not be adequately satisfied by an HPS lamp.
The Super Grow SGL6 product has been designed so that 16 units will provide light in the full visible spectrum and into the far red range. This exceeds the radiometric power provided by a 1000W HPS grow lamp but with electricity costs less than ½ that of the HPS! Two of our SK450 units will cost much less, yet provide more photons to your plants than up to 30 of our SGL6 units.
We further intensify photon delivery by gathering every last bit of light and narrowing the output, wasting nothing and providing a precise output that can be used for accurate crop planning.
Green-to-amber light – It has been proven in many laboratories, including our own, that green and amber lighting is usable by almost all organisms, but most LED grow lights on the market omit them. Our full spectrum output is generous in these frequencies.
Far-red light – We include a healthy dose of far-red light, quite often omitted in HPS lamp technologies and also from our LED grow light competitors. Light in this spectrum is used to precisely control plant photoperiods.
Affordable and predictable design
The low entry cost of the SGL6 allows you to start a small crop or to supplement your existing crop with LEDs, adding more SGL6 as your grow cycle and/or budget allows.
The outputs of the SGL6 and SK450 are formed by precision lenses made of optical-grade acrylic. These lenses capture every bit of usable light and produce a specific and well-defined shape and when they’re properly mounted, insure no dim or dark areas on your crop. Basically, all Super Grow LED lighting may be combined with additional units to accommodate any size or shape of grow area.
Save $$$ – Long term ownership
Although the cost to buy Super Grow LED grow lights is more than traditional 1000W HPS lighting configurations, for the long term grower a return on investment is possible within the first 12-18 months, or approximately within the first 4-6 grow cycles. After that period, the savings are significant over traditional HPS and MH lighting.
This is taking into account electricity and lamp changes only and does not factor in sales of your additional crops. To see what you can save over the lifetime of a Super Grow LED.
How many and which type of Super Grow LED’s should you use?
Selecting the right number of LED grow lights is a two-step process
Step 1 – “Buy enough lights to cover your crop”
LED lights, due to their precision outputs, have a fairly constant light output/footprint. The size of this footprint is based upon the mounting height. As an example, take a flashlight and shine it on a wall. Move it closer and the “footprint” gets smaller – it’s the same concept with LED grow lights. As with any light, there is a maximum distance it should be away from your plants. This is to maximize the number of photons delivered to your crop.
Step 2 – “Add lights to reach your desired yield”
Even novice growers achieve 1 gram per Watt (gm/W) of dried harvest with our grow lights (using ghost chilis as an example). Super Grow LED grow lights drawing 75 Watts can be reasonably expected to achieve 75 grams of dried harvest. 500 Watts of our lights should yield 500 grams. If you desire a greater yield, add lights at a rate of 1gm/W however our pro. growers with the right nutes and air get closer to 1.5 grams per Watt so just one SK450 could produce up to 375 grams of dried material.
Comparison and conclusion
Super Grow LED grow lights (SK450 and SGL6) are a culmination of a decade of research and development in grow lighting technology and a cumulative engineering experience of over 30 years in the lighting industry. When following some simple rules to grow your next harvest, you will experience harvests exceeding HPS and other LED grow lights, as measured in grams per Watt.
