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!

Slim Profile. Seamless Integration.

The ideal supplemental greenhouse grow light should be just that — supplemental. We designed the Pleiades with a slim profile for seamless installation along the existing truss infrastructure in your greenhouse. This seamless integration casts no additional shadows, making it the perfect supplemental light source for your greenhouse.

PPF:

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.

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.

Automated Light Response

Every Pleiades system is bundled with ‘Light Harvesting’ sensors that measure the natural light in your greenhouse. Cloud cover? Seasonal daylight fluctuations? The Pleiades with Light Harvesting can self-adjust in increments as little as 1% in real time based on the ever-changing light conditions in your greenhouse.

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.

A Fixture to Last a Lifetime.

It’s no secret that LEDs last significantly longer than legacy HID systems. In a Pleiades 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 Pleiades system is generational.
Buy right. Buy once.

L90:
50,000 hours
(Based on diode manufacturer specs)

L70:
110,000 hours
(Based on diode manufacturer specs)

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.

Cool Diodes are Efficient Diodes.

Heat, improperly-managed, is an efficiency killer. The Fohse engineering team has run hundreds of hours of thermal analysis across many design iterrations of the Pleiades. The design you see here is the best-of-the-best of all those iterations. The result? Efficient photon emission with rock-bottom energy consumption.

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.

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, especially in greenhouses where humidity can turn into condensation and condensation into drips. We built the Pleiades to achieve an IP55 rating, which means drips will never be a problem. In fact, with an IP55 rating you can hose your fixtures down post-harvest without ever taking them down.
That’s a real time saver.

Ingress Protection Rating:
IP44

Ingress Protection testing really puts our fixtures through the ringer : sandblasting, water spray, pressure washing, submersion, etc. Rest assured your Pleiades is well-protected from the hazards of your grow environment.

Easily Integrate

Turning your greenhouse into a state-of-the-art LED grow operation is fast work with the Pleiades. Easy-to-install truss brackets make installation a breeze. Additionally, the ability to daisy-chain power between multiple fixtures means no overhaul of your existing electrical infrastructure. This means that soon after you receive your Pleiades system you’ll be growing in no time!
