How Much Light is Too Much?
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.
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!
Savings Add Up (and so do yields)
Every year the wholesale price for flower and biomass is dropping. What’s more, the global cannabis market is consolidating even before widespread legalization has occured. Top that off with energy restrictions popping up in various markets aroud the world. With this in mind, it’s obvious that any licensed cultivator needs every edge they can get.
We know the biggest barrier to entry with an LED grow light system is the upfront cost. When you break down the operating cost figures as compared to an HPS system, reality sets in – can you afford not to go LED? See for yourself.

Greenhouse Toplighting Methods
Not every greenhouse is created equal, which is why we’ve developed two distinct models for greenhouse illumination. With the O6i model you’ll be able to achieve the highest amount of supplemental light, cast the widest footprint, and do so with 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. Whichever your preference, our team will help you make the right decision.
Ultimate Uniformity
The Pleiades is designed around the idea that there is strength in numbers. Every fixture in a full Pleiades system works together to deliver best-in-class light uniformity with less than a 10% variance in PPFD levels. Consistent harvests begin with consistent light levels, and the Pleiades is the right tool for the job.

Precision Light Planning
If there’s one thing we’ve learned touring close to a thousand cultivation facilities around the world, it’s that every environment is unique with its own special requirements. When you work with Fohse, our partnership kicks off with a thourough review of your grow room plans and your goals. Our light planning team heads into our simulation software to develop a 100% custom configuration tailor-fit to the unique needs of your operation. We can even take it a step further and predict your cost of cooling, cost of electricity, and how much you’ll save owing an Pleiades system over time.

DLI Planning
In greenhouse environments your primary light source is an ever changing variable, so meeting your light intensity and consistency needs comes down to proper Daily Light Integral (DLI) planning from the start.
1
CONVERT TARGET PPFD TO DLI
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 |
| 1,000,000 μmol/mol |
2
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.
3
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.
4
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.

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 Pleiades luminaires is as simple as dividing the L-figures by the number of hours of daily use. If you were to run your Pleiades 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 Pleiades system at full power. Sometimes you won’t even run it at all. When we say “Buy right, Buy once” we truly mean once.

Make a Friend Out of Heat
Unlike obsolete plasma grow lights the Pleiades has no massive ‘infrared spike’ hidden on the far ends of its spectrum, meaning drastically less heat radiating down on your canopy.
Higher Harvest Quality
More cannabinoids and better terpene profiles means you’ll enjoy some of your best harvests yet with the Pleiades.
Less AC
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.
Even Warmth
A reduction in radiative heat and chilled air compensation makes for a much more even LST temperature throughout your upper to lower canopy.
More Bud Growth
An even canopy LST temperature promotes more RuBisCO reactions down your canopy, leading to more instra-canopy bud development.
More Cannabinoids
Cannabinoids are heat-sensitive. No more destructive IR spike means more cannabinoids make it to harvest.
More Terpenes
Terpenes are also heat-sensitive compounds and degrade at higher temperatures. Enjoy some of your best terp profiles ever with the Pleiades!
Made for Damp Environments
That’s a real time saver.
