FOHSE is the world’s leader in LED grow technology for greenhouses. Every light we manufacture includes patent pending technology that puts FOHSE ahead of our competition. We developed and manufactured the O6i to feature a compact size with significant output – which means more biomass for a successful crop. We aim to give every client the best price on the O6i as possible while packing more photons into each footprint than any other greenhouse light on the market. When you contact our lighting experts they will identify every opportunity for cost savings on FOHSE O6i greenhouse grow lights – such as volume discounts – that will be passed along to you.

Features
Compact Size. Significant Output.
Central to your crop’s success is the idea that greater photon density leads to more carbon assimilation, which means more biomass for a successful crop. The O6i packs more photons into each footprint than any other greenhouse light on the market. It is paired with a spectral distribution ideal for complimenting natural sunlight.
CO2 Requirements
Growing under high-intensity light conditions will require you to recalibrate every aspect of your environment, and chief among that is CO2! We advise all our clients to supplement at least 1200ppm of CO2 in their environment. Keep a close eye on your plants and take detailed notes every crop cycle to find the sweet spot. CO2 gives your crop the carbon building blocks they need to build biomass, and without an adequate amount it won’t matter how much light your system throws down.

Greenhouse Toplighting Methods
Not every greenhouse is created equal, which is why we’ve developed two distinct models for greenhouse illumination. The O6i model gives the maximum amount of supplemental light, casts the widest footprint, and uses fewer fixtures.
By contrast, our Pleiades model is lower powered with a slim profile designed to line the trusses of your greenhouse. It is best-suited for greenhouses and hoophouses where uniformity and efficacy are the priorities.
At Fohse, we design and build the best grow lights for cannabis on the market for any grow space. Whichever your preference, our team will help you make the right decision.
Precision Photon Density
O6i is designed to make switching from HPS to LED as easy as possible without overhauling electrical or truss infrastructure. It offers 50% greater output than a 1000W DE HPS. These energy-efficient greenhouse grow lights also provide 42% greater efficacy. No infrared spike generating unnecessary heat.
Precision Light Planning
We have toured close to a thousand cultivation facilities around the world. This has taught us that every environment is unique with its own special requirements. When you work with Fohse, our partnership kicks off with a thorough review of your grow room plans and your goals.
Our light planning team heads into our simulation software to develop a 100% custom configuration. This configuration is tailor-fit to the unique needs of your operation. We can even take it a step further. We can predict your cost of cooling, electricity, and how much you’ll save by owning an O6i system over time.
At Fohse, we put you first during every stage of growth. Our O6i is the proof we are dedicated to building efficient LED lights to grow plants that meet our clients needs.
Automated Light Response
An O6i system is bundled with ‘Light Harvesting’ sensors that measure the natural light in your greenhouse. It doesn’t matter if it’s exposed to cloud cover or seasonal daylight fluctuations. The O6i are the greenhouse grow lights that adjust to any amount of light.
Light Harvesting allows for self-adjustment in increments as little as 1% in real time based on the ever-changing light conditions in your greenhouse. This makes it one of the most flexible and better performing LED lights to grow plants.
U.S. Daily Light Integral Map
Daily Light Integral (DLI) represents the total photosynthetically active radiation accumulated over one day. Since plants are essentially accumulators of solar radiation, this measurement is extremely useful for describing solar radiation as it affects plant growth with particular emphasis on estimating and building a supplemental lighting system. A set of 12 monthly DLI maps for the lower 48 states and based on solar radiation data from 1961-1990 was published in HortTechnology in 2002. An updated set of monthly DLI maps based on solar radiation for all 50 states during 1998-2012 is presented here. Select a month, then click on a location in the map to open a table with annual and monthly DLI values.

In greenhouse environments your primary light source is an ever changing variable. As a result, meeting your light intensity and consistency needs comes down to proper Daily Light Integral (DLI) planning from the start.
The Last Fixture Purchase You'll Make
It’s no secret that LEDs last significantly longer than legacy HID systems. In an O6i greenhouse with Light Harvesting technology the effect of this truth is compounded considerably. By running the fixtures only when and as much as needed, the lifespan of your O6i system is generational.
With the O6i you get long-lasting and cost-saving greenhouse grow lights that don’t require constant maintenance. Enjoy the best grow lights for cannabis without constant upgrading with the O6i. Buy right. Buy once.

Bulbs Die Suddenly. LEDs slowly fade.
Our L90 and L70 figures come straight from the data sheets and stress-testing provided by our diode manufacturers. Predicting the PPF degradation of your O6i luminaires is as simple as dividing the L-figures by the number of hours of daily use. If you were to run your O6i fixtures at full power for 12 hours a day you can reasonably expect its PPF to reduce by 30% over the course of 25 years. But this is only part of the picture. In practical use, you’ll rarely (if ever) run your O6i system at full power. With the O6i you get the best grow lights for cannabis on the market the first time around. When we say “Buy right, Buy once” we truly mean once.
Cool Diodes are Efficient Diodes.
That’s our secret to packing so much power into each footprint with the O6i. LED lights to grow plants. Aircraft-grade aluminum heat sinks and two hyper-efficient variable speed fans keep the O6i’s LEDs operating at peak efficiency. Add to that the lack of IR spike rampant in HID systems, and you have a greenhouse where heat can be an ally.

Make a Friend Out of Heat
Unlike obsolete plasma grow lights the O6i has no massive ‘infrared spike’ hidden on the far ends of its spectrum. This means drastically less heat is radiating down on your canopy.

Without the IR spike cooking your upper canopy, you’ll need far less cooling to compensate in order to keep your LSTs in an optimal range.

A reduction in radiative heat and chilled air compensation makes for a much more even LST temperature throughout your upper to lower canopy.

An even canopy LST temperature promotes more RuBisCO reactions down your canopy, leading to more instra-canopy bud development.

Cannabinoids are heat-sensitive. No more destructive IR spike means more cannabinoids make it to harvest.

Terpenes are also heat-sensitive compounds and degrade at higher temperatures. Enjoy some of your best terp profiles ever!

More cannabinoids and better terpene profiles means you’ll enjoy some of your best harvests yet. Experience the results of the best full-spectrum LED grow lights.
Made for Damp Environments
Any controlled cultivation environment is susceptible to the rigors of fluctuating humidity. That humidity can be a serious risk to sensitive electronics. This is especially true in greenhouses where humidity can turn into condensation and condensation into drips. We built the O6i to achieve an IP65 rating, which means drips will never be a problem. In fact, with an IP65 rating you can hose your fixtures down post-harvest without ever taking them down. The O6i are the best grow lights for cannabis for a reason, they are a real time saver.
That’s a real time saver.
IP65
Ingress Protection
Ingress Protection testing really puts our fixtures through the ringer. We test out sandblasting, water spray, pressure washing, submersion, and more. Rest assured your O6i is well-protected from the hazards of your grow environment.
Easily Integrate With Your Environment
With the O6i design, we wanted to make the transition to LED grow lights as seamless as possible for greenhouses that currently use HID systems. True to its position as one of the best grow lights for cannabis, the O6i is simple. You only need to plug it in, and it’s ready to achieve unmatched results.
