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.

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.
When you manufacture the most powerful grow light in the world, this is a question we often get. The short answer is your plants will tell you. The deeper answer is, well, it depends on what other factors in your environment are limiting your crop from fully utilizing all available light – watering schedule? Leaf surface temperature? Ambient CO2? Genetics?
For our cannabis clients, the question is actually ‘How much light can cannabis take?’ The answer to that question is, we really don’t know (click the link to listen to Dr. Bruce Bugbee’s thoughts on the matter).
On of our clients in Michigan is really pushing their genetics to find out, and after setting back-to-back, record-breaking harvests all throughout 2020, they still haven’t found the top! Follow this link for a brief summary of their results over 40 harvests.
Ever notice how most spectral charts for grow lights stop around the far-red region? That’s because extending the chart into the infrared region would show one of the biggest problems with plasma-burning light sources… an enormous spike of radiative heat!
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.

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.

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.

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.

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.
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.
