The Cultivator LED Plus provides great value and exceptional color balancing for LED lighting with our proprietary lenses manufactured by Carl Zeiss Vision.
Lenses are polycarbonate with 100% UV protection and Flash Silver exterior lens coating. Like other premium eyewear and unlike typical value eyewear, these lenses are decentered (asymmetrical) to eliminate distortion that would otherwise occur with a curved lens. The Cultivator frame features a rubber nose pad which holds the frames comfortably for hours, even in hot conditions. Microfiber pouch included for proper cleaning and storage.
Method Seven makes optics for gardeners
We've been working with grow lights for over 20 years. We've tolerated the discomfort. Some of us experience night-blindness, see spots get headaches and we know a few who have gone through retina replacement surgery. Not fun.
We've solved all these problems. We can all go back into the grow and start enjoying our plants, safely and comfortably. We've got you covered for any type of lighting. Try them or ask anyone who has. You've got to see to believe.
Method Seven offers two lines of grow glasses for HPS lighting environments. Method Seven Rendition HPS delivers "Perfect Color" for the world's ultimate grow experience in the intense yellow spectrum and harsh conditions of HPS lighting. They deliver absolutely the highest available optical clarity and ability to absorb infrared (heat). These are THE best lenses for the professional working extended hours under HPS or the passionate hobbyist who simply wants the best. The “plus” silver coating option makes our glass lens even better for working in high wattage environments or crossover use outside. Plus, they just look cool :-) Our patent pending formulation is manufactured with the highest quality German durable mineral glass to provide perfect color, perfect clarity, and 100% UV protection.
Our synthetic lenses are manufactured for Method Seven by Carl Zeiss using Method Seven's unique lens technology and provide optimized color under HPS. And they provide exceptional clarity due to the high optical standards obtained by Carl Zeiss. They are very lightweight and unbreakable. We recommend our synthetic lenses to anyone with one grow light or who spends minimal time working under lights. The value of our synthetic lens makes these products great for outfitting larger crews who are working under lights but may not be making critical plant health and harvest decisions. Available either uncoated or silver coated (combining your indoor grow and outdoor lifestyle), 100% UV protection, and great value.
Both glasses provide benefits that clearly exceed the performance of all competitors.
Sunglasses are not for grow rooms!
Grow rooms have lots of light, but it's not broad spectrum. Great for plants, but not your eyes. The rods and cones in your eyes need broad spectrum light to focus, see shapes, notice movement and see color. When you wear sunglasses, you make this worse - you darken all the light, so you squint less, but you still can't see color and it's even more difficult to focus. Things look muddy. Your brain struggles to compensate. That's where fatigue and headaches come from.
Method Seven Optics filter the harsh lighting and bring balanced color to your eyes. It's like working in full daylight, naturally. you can see foliage properly, spot pests and deficiencies early and easily. your brain relaxes. No headaches, no strain, and no long-term damage. Our glasses even eliminate the strobe effect produced by most HPS ballasts. And there's no adjustment period when you walk out of the grow room. With Method Seven, you can work with accuracy, comfort and safety.
See. Believe. Your eyes are worth it!
Cheap lenses distort light as it enters your eye. Like seeing double, or slightly cross-eyed, or just hazy. Focus and clarity are compromised. You may not notice it right away, but then again you can live for several minutes with a plastic bag stretched over your head. Doesn't mean you should do it.
Method Seven Rendition lenses are made in Germany from glass, melted in six ton batches to achieve perfect clarity with your Patent Pending formulation. They are asymmetrically ground and polished and built into custom frames in Italy. This is perfection.
Our distortion free polycarbonate and nylon lens are made by Carl Zeiss. The absolute best synthetic lenses in the world. Your eyes are worth it!
Custom RX available for all spectrums.
HID lights are serious!
UV damage is cumulative, like a small sun-burn on your cornea and retina with each exposure. No one talks about UVC from the Sun because it's filtered by the upper atmosphere. Surprise! It's the most dangerous UV and is produced by most HID lights. Method Seven lenses protect from ALL harmful UVA/B/C rays. Don't risk it. You think going to the dentist is expensive and painful, try a cornea replacement. PS: for extended hours in a grow room, a visor and sunblock is also a good idea...
Method Seven technology blends incredible color balancing for each of the standard grow lighting spectrums (HPS, Metal Halide, LED, Sun) with exceptionally high quality lenses that provide the best in optical clarity. Additionally, Method Seven protection removes all harmful UV A/B rays like most others but additionally also removes harmful UVC rays which are filtered out of sunlight by the upper atmosphere, but pose a significant hazard under grow lighting.
Many growers suffer through unnecessary stress, fatigue, decreased yield, and even permanent eye injury from using sunglasses or cheaper knock-off grow room glasses. At best, even premium sunglasses attenuate (decrease) excess light in the grow room but do a horrible job of color balancing in indoor lighting environments, leading not only to discomfort and stress, but also to poor viewing and maintenance of your plants. Cheap grow room glasses do an okay job of color balancing, but typically have very poor optical quality and inadequate protection from UVC rays.
Treat yourself and your grow to Method Seven quality and style!
Q: Do Method Seven Glasses work outdoors?
A: YES! YOU CAN WEAR YOUR METHOD SEVEN'S OUTDOORS TOO! Method Seven Technology blocks and completely protects your eyes from all harmful UVA/UVB/UVC light. Our glasses are appropriate to wear outdoors under any conditions which you choose. The HPS spectrum lenses filter out less visible spectrum light than most medium and dark sunglass lenses which means they are a great choice for lower light conditions, like mountain biking in the trees or skateboarding in the early morning, but they may not be your first choice for snowboarding on a sunny day when conditions are super bright. In very bright outdoor conditions the MH Silver Plus+ lens is a fantastic outdoor lens. Made from unbreakable polycarbonate; it’s a great choice for action sports. (LED glasses are not recommended for outdoors).
Q: Why bother with grow glasses?
A: SEE. BELIEVE. While HPS, Metal Halide, and LED lighting can provide effective lighting solutions and deliver plants the light energy needed for prolific vegetative growth, they also create a hostile working environment for the human eye. Humans see best under the balanced spectrum and light levels of natural daylight conditions. Grow room lighting produces extreme conditions of excess light, very unbalanced light from unique spectrum of each artificial grow light source (HPS, LED, MH), and dangerous UV radiation from UVA/UVB/UVC.
Sunglasses help attenuate (reduce) the excess light, but do nothing to help color balance the stressful and eye fatiguing spectrums of indoor garden lighting. Cheap grow glasses offer some improvement here, but usually at a much lower optical quality than good sunglasses. Both might not protect from UVC radiation which is not a significant concern in natural sunlight due to absorption by the earth's atmosphere but which is a concern in the modern grow room.
Only Method Seven provides definitive color balancing with options for all common indoor lighting sources, exceptional clarity, and 100% UVA/UVB/UVC protection. Don’t risk using sunglasses or cheap grow room glasses!
Q: Why are Method Seven's so superior to other grow glasses?
A: SEE. BELIEVE. Grow room lighting produces extreme conditions. The hazards include excess light, very unbalanced light from the unique spectrum of each artificial grow light source (HPS, LED, MH), and dangerous UV radiation from UVA/UVB/UVC. Ballasts used by HPS and MH grow lights also creates a high frequency strobe effect in the light from these bulbs. This is not immediately obvious to the conscious mind, but is very stressful to your eyes and impedes ability to easily focus on shapes and detect movement. Working in these environments without appropriate eyewear results in eye and general fatigue, inability to correctly monitor plants, and even permanent injury to your eyes. Method Seven Optics are designed and engineered specifically and carefully for these conditions.
All Method Seven lenses are made from either premium German mineral glass or high quality synthetics manufactured to our custom standards by Italy's Carl Zeiss - world leaders in optics for over 100 years. All are asymmetrically tuned bringing distortion free focus and clarity to your eyes. Rendition glass lenses virtually eliminate the strobe effect, and Carl Zeiss synthetic lenses reduce this to physiologically low levels.
Other grow glasses attempt to color balance the extreme light spectrum of the grow room with varying degrees of success, though even those with decent light balancing typically use cheap plastic lenses with very poor clarity that distort light and are hazy or blurry. With cheap grow room glasses, your eyes and brain work overtime to compensate and you can experience fatigue, see spots, get headaches and in some cases experience damaging UV radiation.
Your eyes and health are very important. So is getting the most out of your grow. Don’t risk using sunglasses or cheap grow room glasses!
Q: Where are Method Seven glasses manufactured?
A: SANTA CRUZ INSPIRATION, GERMAN & ITALIAN CRAFTSMANSHIP. Our Rendition Perfect Color HPS mineral glass lens is made with a patent pending formulation, melted in six ton batches in a century old German factory, and ground, polished, cut and hardened in Italy.
Our synthetic lenses are made by Carl Zeiss - world leaders in optics for over 100 years. They are asymmetrically tuned bringing distortion free focus and clarity to your eyes.
Our frames are made in Italy. Final assembly of glasses into frames is also done in Italy. Packaging of glasses, carry case, wiping cloth, and boxes is done in Italy or in Santa Cruz, California.
Q: What's the story with Rendition "Perfect Color" HPS lenses?
A: COLOR BALANCING. We developed a proprietary blend of rare-earth elements that are bonded within molten glass at the molecular level. The result is canceling of a precise nanometer of light energy from the High Pressure Sodium spectrum. The lenses also selectively filter the remaining light spectrum to create the white balanced light your eyes need for maximum performance and comfort. The specific density of the glass lens also absorbs a substantial amount of infrared radiation resulting in additional comfort. Rendition Perfect Color HPS lenses provide the ultimate in color balancing, optical clarity, and protection to allow you the ultimate in comfort, visual acuity, and productivity while working with your grow.
Up your game as you as monitor plant health and correctly perceive the color of your plant leaves and the things that threaten your grow - pests, disease, rot, mildews, and mineral deficiencies and excesses - that are often hidden by the harsh lighting environment. The Rendition lens reveals color precisely enough to use a PH test strip while in the grow room. All without turning your HPS lighting off or walking your plants, or your testing equipment into daylight. (If you are the kind of person who wants to know the details, you can read about the amazing science behind in links further down this page).
OPTICAL CLARITY. Rendition Perfect Color HPS lenses are made from mineral glass which is melted in six ton batches in a century old German factory, and ground, polished, cut and hardened in Italy. They provide the ultimate in distortion free focus and clarity to your eyes.
PROTECTION. Like all Method Seven optics, Rendition lenses provide 100% protection against not only UVA and UVB radiation, but also from UVC radiation lacking in normal daylight but prevalent under grow-room lighting. Rendition lenses are also the only grow lenses in the world that eliminate virtually all of the high frequency strobe effect inherent under HPS grow lights due to the way ballast and HPS bulb product light (the strobe effect is not immediately obvious to the conscious mind, but is very stressful to your eyes and impedes ability to easily focus on shapes and detect movement, and is a huge contributor to eye fatigue when working for prolonged periods in and HPS lighted grow room).
Experience "Rendition Perfect Color" under HPS lighting - and work unconstrained in spite of that environment.
Q: Why does Method Seven offer so many options?
A: WE PROVIDE AN EXTENDED ASSORTMENT OF GLASSES BECAUSE... gardeners employ a variety of lighting types and combinations of lights to work their craft! Each type of light produces its own unique spectrum that is very different from the light levels and balanced spectrum of daytime sunlight which works best for our eyes. We make optical solutions for each of the most common of these lighting spectrums. Our glasses allow you to regain the comfort and high quality visual results you would experience in an outdoor garden environment. We also offer clip-ons for people who need prescriptions"
COLOR, CLARITY, PROTECTION
All Method Seven glasses provide outstanding Clarity, and 100% UVA/UVB/UVC protection.
Optics & Spectrum Info
NATURAL SUNLIGHT AND WHITE BALANCED LIGHT. Sunlight is composed of the full, balanced distribution of light across the spectrum of visible wavelengths from 390 to 750 nm - a magical distribution of reds, yellows, greens and blues - all the colors of the rainbow. Sunlight's even distribution of all wavelengths of light across the full spectrum produces naturally “balanced white light” (BWL). Our eyes and brain need this color balanced light to function optimally without stress, discomfort, fatigue and sometimes permanent damage. This broad spectrum of light allows us to see natural looking colors and to also easily recognize shapes and motion. The sunlight spectrum also includes invisible and dangerous UV (ultra violet) and invisible and fatiguing IR (infra red) wavelengths.
GROW ROOM LIGHTS
Each grow-room light source (HPS, MH, LED) provides a VERY imbalanced spectrum of light, with a vast majority of the light occurring in just a few wavelengths of the spectrum typical of the chemistry and physics of that light source. Plants still grow well under these imbalanced light sources and aren't negatively affected, but human eyes and brains are.
COLOR, CLARITY, PROTECTION. ONLY METHOD SEVEN DELIVERS ALL THREE.
The greater productivity, comfort, and safety, the grower needs grow glasses that filter the harsh, unbalanced light of the grow room to create BWL (balanced white light). Each lighting spectrum (HPS, LED, MH) needs its own exacting solution. Method Seven Optics have formulations to filter out the specific wavelength spikes in the spectrum of each of these common grow lightings sources, providing the wearer white balanced light within the very unbalanced environment.The lenses must do this without reducing the optical clarity of the naked eye, or the reduced optical clarity from the lenses create a different set of physiological issues for the wearer. For short term comfort and long term health, lenses must protect the eye from 100% of the harmful UVA/UVB/UVC radiation of the grow room and reduce IR exposure to the eye.
HPS lighting creates and radiates a huge amount of light. The frequent electrical excitation and decay of electrons in the sodium atoms generates the vast majority of total light output at a specific "yellow" wavelength around 590 nanometers. This wavelength is a very suitable energy source for plants to use for photosynthesis and growth, and light and ballast costs have traditionally been low. HPS lights use considerable electricity and produce considerable excess heat. The yellow spike of HPS lights is especially challenging to our eyes due to the poor spectrum, the exceeding poor yellow / blue ratio of the light that impacts the functioning of the rods and cones in our eyes, and the high frequency "strobe effect" from the ballasts (more details elsewhere on this page).
Unlike most HPS lamps, the light spectrum produced by commercially available LED equipment varies between manufacturers and is dependent on the combinations of diode, amperage, magnification and a host of design considerations. The best LED spectrums for optimum plant growth typically produce a distinctive magenta color appearance.
MH bulbs produce light that's strongest at the blue end of the spectrum resulting in a stark, bright white light. MH bulbs tend to be very bright, and glasses need to appropriately attenuate (decrease) total light to the eye in addition to providing color balanced light and 100% UVA/UVB/UVC protection.
Our eyes evolved to function best under daytime sunlight with its full, balanced distribution of light across the full spectrum of red, yellow, green and blue wavelengths from 390 to 750 nm. Our eyes and brain need this color balanced light to function optimally without stress, discomfort, fatigue and sometimes permanent damage. This broad spectrum of light allows us to see natural looking colors and to also easily recognize shapes and motion.
"BALANCED WHITE LIGHT"
When reproducing the full sunlight spectrum artificially, the spectrum is called "balanced white light" (BWL). Each type of grow light (HPS, LED, MH) produces a spectrum very far from white balanced light. Photographers learned long ago that the color of light on an object changed the way a camera/film registers the color of the object, just as the color of light on an object changes the way our eyes perceive the color of that object . With the advent of modern light metering and photo processing software, photos can be white balanced after the fact. Photographers have created a process where they photograph a specific color of white paper at the same time they take a photograph, and later adjust the finished photographs (using photo software like Photoshop) until that white paper looks the correct shade of white again. This allows the other objects photographed to appear the correct color too.
When looking at something under a spectrum other than balanced white light, your eyes work hard and partially color correct what they see. The more unbalanced the spectrum, the harder your eyes work and the less they can successfully compensate. Look at a sheet of white paper under grow lights, and you will notice that it doesn't look even close to white, instead you see the unbalanced color spikes of the grow room light source. Your eyes can't come close to compensating for the extreme lighting environment of indoor grow lights. Look at that same piece of paper with Method Seven glasses, and see the exact shade of white you see outdoors under natural sunlight! For more technical information about color balancing, eye physiology and specific Method Seven products, see the "Color Perception & M7 Color Balancing" section lower on this page.
COLOR, CLARITY, PROTECTION
Light balancing is only one of the challenges for optical products for the indoor grower. Only Method Seven delivers products for different light source spectrums with state of the art color balancing, optical clarity, and 100% UVA/UVB/UVC protection.
Method Seven Rendition Perfect Color HPS lenses are made from high grade mineral glass. The elements added to the glass are atomically bonded into the crystalline structure. There are no emulsions or dyes to interfere with optical clarity. Method Seven's synthetic lenses likewise provide exceptional optical clarity. These lenses were developed in partnership with Carl Zeiss, a 100 year old Italian lens manufacturer well known for the optical quality of their lenses.
The best glass lens sunglasses on the market match the optical clarity of the Rendition mineral glass lenses (but don't color balance for indoor growing, and may not protect from UVC radiation). Less expensive sunglasses and cheap grow glasses have poor optical quality and contribute to eye stress and fatigue.
Eye Protection & safety standards:
PROTECT YOUR EYES! Find yourself constantly squinting in the grow room? Over time constant exposure to high levels of UV and infrared radiation leads to irreparable eye damage. Loss of color perception, cataracts, and the destruction of your night vision are possible. All of our lenses blocks all harmful invisible wavelengths (UVA, UVB, UVC and Infrared). Your plants require these invisible wavelengths to flourish. Your eyes certainly don’t.
But that's not the whole story. Cones and rods within your eyes control the eyes ability to focus and function best at light wavelengths very different from the indoor grow environment. New science proves that the eyes extra effort to focus and correct for excess yellow from HPS lights causes a host of eye strain and health problems. Rendition lenses balance the light in a way that allows your eyes, brain, and body to function correctly again. This results in drastically less mental strain and fatigue. Less fatigue equals better decision-making and a pleasant experience in your grow room.
Method Seven glasses meet or exceed international safety tests for optical quality, clarity, breakage and UV protection.
HPS lighting story:
High Pressure Sodium (HPS) lighting has long offered a cost effective solution for some industrial applications such as the lighting of warehouses and for Grow Room lighting. HPS lighting also creates visual problems for people working within its environment. The details of these visual problems are discussed in our eye physiology section. But in general, HPS lighting causes significant decrease in color perception and ability to focus on shapes and motion. The "strobe" light effect caused by the high frequency, cyclical variation in power from the HPS ballast to the bulb causes a similar high frequency variation in light intensity which also has negative impact on our eye's ability to function comfortably and effectively under these lights.
HPS lighting creates and radiates a huge amount of light. The frequent electrical excitation and decay of electrons in the sodium atoms generates the vast majority of total light output at a specific "yellow" wavelength around 590 nanometers. This wavelength is a very suitable energy source for plants to use for photosynthesis and growth.
This same concentration of yellow light makes it difficult for an individual to see properly. Humans see best in natural sunlight, or in “Balanced White Light” (BWL). BWL light, like natural sunlight, covers the entire visible spectrum of 390 to 750 nm. This broad spectrum of light allows us to see natural looking colors and to also easily recognize shapes and motion. Under HPS lighting our eyes are saturated with yellow light and we are unable to recognize any other colors.
Human eyes also require a certain ratio of blue light (around 505 nm) to yellow light (around 555 nm) to be able to recognize shapes and to detect motion. HPS lights provide some of this blue light, but in far to low a ratio compared to the prevalent yellows, and this profoundly degrades our ability to focus. This point will be explained further in the discussion of “rods” and “cones.”
COLOR, CLARITY, PROTECTION. METHOD SEVEN DELIVERS!
Others can try to copy but fall short: Method Seven developed the world's first HPS grow glasses and offers HPS glasses with patent pending Rendition Perfect Color HPS technology with German mineral glass or high optical quality synthetic lenses developed with Carl Zeiss (a world leader in high quality optical lens production). Only Method Seven delivers finished glasses of incomparable style and quality and meets your needs for Color, Clarity, Protection!
LED lighting story:
LED (light emitting diodes) grow lights are a relative newcomer as source for indoor horticultural purposes. They are the up-and-coming state of the art. Initial light / fixture costs tend to be higher than HPS and MH, but ... these costs can often be recouped quickly due to much lower energy consumption per lumen, less excess heat in the grow room, and the very long lift of bulbs. Unlike most HPS and MH lamps, the light spectrum produced by commercially available LED equipment varies between manufacturers and is dependent on the combinations of diode, amperage, magnification and a host of design considerations. The best LED spectrums for optimum plant growth typically produce a distinctive magenta color appearance. Method Seven chose Black Dog LED, considered an LED market leader, as the benchmark spectrum for design of the LED specific lens formulation.
The Method Seven LED Optics will balance color optimally under Black Dog LED lights, but has been tested with a number of other commercial LED lights and functions exceptionally well with all other brands tested to date. Color correction might vary slightly with alternative equipment (imperceptible in most cases) but in all cases Method Seven Optics will protect against all UV damaging ray regardless of LED brand.
METHOD SEVEN OFFERS THE WORLD'S FIRST AND ONLY LED BALANCING GROW LIGHTS.
Color, Clarity, Protection. Method Seven delivers!
Metal Halide lighting story:
Historically, in contrast to HPS lighting, Metal Halide lamps have had a higher initial cost but are typically slightly more efficient, produce less (but still considerable) heat, and have a broader, more diverse spectrum of light for plants. MH bulbs produce light that's strongest at the blue end of the spectrum resulting in a stark, bright white light. MH lighting may prove less difficult for the human eye than HPS, but still causes considerable eye strain and great risk from UV radiation. MH bulbs tend to be very bright, and glasses need to appropriately attenuate (decrease) total light to the eye in addition to providing color balanced light and 100% UVA/UVB/UVC protection.
