The Best Grow Lights for Cannabis: The O6i by Fohse
The O6i re-imagines greenhouse illumination. It presents high-quality and powerful greenhouse grow lights in a compact size. With an IP65 rating, the O6i can effectively sustain the humidity inside any grow tent.
The labcoats are triple checking their work. Check back later for this data.
Compact Size. Significant Output.
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
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
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.
North America Seasonal DLI Map
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.
Say you want to maintain a PPFD of 1,000 μmol/m2s throughtout the year and you’re running a 12-hour photoperiod. Here’s the math to convert that to DLI:
|1,000 μmol/m2s × 60 s/min × 60 min/hr × 12 hr/day||= 43.2 mol/m2day|
DETERMINE YOUR REGION’S LOWEST DLI MONTH
For the Northen Hemisphere the lowest DLI month would be December. This information is important for determining how much supplemental light you need to plan for. Consequently you can maintain your target PPFD & DLI during the dimmest month of the year. Use the DLI Map pop-out in this section to estimate your region’s DLI in any month.
DETERMINE YOUR MAX SUPPLEMENTAL DLI NEED
Subtract your minimum naturally provided DLI from your maximum target DLI to get your supplemental DLI need.As an example, the minimum naturally provided DLI in California during December would be 15 mol/m2day. If your maximum target DLI is 43.2 mol/m2day then your maximum supplemental DLI would be 27.8 mol/m2day.
DESIGN A LIGHT PLAN TO MEET YOUR DLI TARGET
The average PPFD target your supplemental light plan should achieve can be calculated by reversing the equation in Step 1. In the case of our example, 27.8 mol/m2day would come out to a PPFD of 643 μmol/m2s.
The Last Fixture Purchase You'll Make
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.Get Your O6i Quote

The IR Spike HID's Dirty Secret
The IR Spike
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.
The IR spike will not be cooking your upper canopy. This means 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. The O6i is the LED light to grow plants that lets you enjoy some of your best terp profiles ever with the O6i!
More cannabinoids and better terpene profiles means you'll enjoy some of your best harvests yet with the O6i.
Made for Damp Environments
That’s a real time saver.
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.

CO 2 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.

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.

The Infrared Spike
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!
