It's About Striking a Balance

The F1V is a high-quality, full-spectrum light that completely transforms vertical grow spaces. These are truly the best grow lights for indoor plants. The F1V offers commercial growers:

Plenty of power.
No thermal excess.
The opportunity to never again move your lights to 'chase canopy'.
PPF: 2,600 μmol/s (Options up to)
PPE: 2.55 - 2.60 μmol/J (Options up to)

The Challenge of Vertical Lighting

Cultivating dense canopies in a commercial-scale, vertical environment presents an interesting lighting challenge. HID lamps have the power, but their excessive heat rules them out for close-to-canopy growing. Early-generation LED fixtures alleviate the heat issue, but fall short on photon delivery. Right in the sweet spot is where we designed the F1V grow lamp. With the extra power draw, your control over the light levels is accomplished digitally via a touchscreen controller. As one of the best led grow lights for vertical farming, the F1V removes the need to manually raise or lower your fixtures to ‘chase the canopy’. Offering this relief is one of the many things that make it the best LED grow lights for cannabis.

Precision Photon Density

Uniform photon density is key to predictable crop performance. When we're finished planning, simulating, installing, and calibrating your F1V system, you'll be growing under uniform light levels. The F1V claims the title of best LED grow lights for cannabis thanks to its great precision. It doesn’t deliver hot or cool spots, just steady heat and power through the entire coverage area.

At Fohse, we work to deliver solutions that fit your individual lighting needs. Featuring configurations that are customized to your own grow tent, your F1V is truly yours. We also provide cooling and power consumption estimates to present how these unique LED lights can lower your costs. Enjoy the best full-spectrum LED grow lights on the market with the F1V.

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 F1V system over time. Its energy-efficient attributes also make the F1V one of the most attractive options on the market. If you’re looking for the best LED grow lights for cannabis, the F1V claims the title.

Multiple Configurations

Every F1V is custom made to order, which means we build these led grow lights for vertical farming to suit the specific parameters of your cultivation environment. The F1V 420W and 600W models are typically suited for vegetative growth. On the other hand, the F1V 800W and 1000W models perform best in flowering environments.

At Fohse, we care about transparency and we explain in full detail how we obtain our performance figures. The F1V goes through 4 steps of a thorough design and testing process. This process includes using industry-best practices and certified, 3rd party verification. This helps us ensure the F1V truly has the figures to be the best full-spectrum LED grow light on the market.

How Fohse Verifies Levels

We are keenly aware of the discrepancy between the performance figures many of our competitors report and what is actually observed in practice. At Fohse, we value transparency, and this discrepancy is a problem for everyone. That's a problem for everyone. So, full disclosure, here's how Fohse works:


During the design phase, our engineering team is constantly running calculations to predict the performance of our fixtures. We analyze power consumption, efficacy, BTU load, and more.


Next, during the prototyping phase our engineering and manufacturing teams work together to bring the design to life. This includes using onsite instrumentation like a spectrophoto-colorimeter with integrating sphere to verify all the calculated performance figures.


Third, during the manufacturing phase we ensure our production lines and processes maintain the consistency of the final prototype design. This includes spot checking along the way. Additionally, we bring in third party quality control to inspect every fixture we produce before shipping to the customer.


Lastly, we send each fixture model off to Underwriters Laboratories or Edison Testing Laboratories. They provide 3rd party verification of every claim we make on our fixture spec sheets. They confirmm output, power consumption, Ingress Protection, and other key figures. This crucial step is how we earn your trust in a sea of disinformation. We know we fabricate the best grow lights for indoor plants, this step just confirms it.

An Investment That Endures

Low cost HID systems like ceramic metal halide or high-pressure sodium systems are attractive. However, if you dig a layer deeper into the accumulating costs of perpetual bulb maintenance, the ugly truth becomes readily apparent. The best grow lights for indoor plants require full and long-term functionality. The F1V eliminates ongoing and perpetual maintenance costs entirely.
Buy right. Buy once.
L90: 45,000 hours (Based on diode manufacturer specs)
L70: 110,000 hours (Based on diode manufacturer specs)

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 F1V luminaires is simple. It takes dividing the L90 or L70 figures by the number of hours of daily use. Take the F1V 1000W as an example: if you run the fixture at full power for 12 hours a day, you can reasonably expect its PPF to reduce by 30% over the course of 25 years. Keep in mind this L70 estimation will likely extend even further. This is because you’ll only run your fixtures at full power near the end of a growth phase. When we say “Buy right, Buy once” we truly mean once. With the F1V you get the best LED grow lights for cannabis on the market the first time around.

Thermodynamically Balanced

The F1V form factor is a dual-purpose design. It utilizes passive cooling to keep the diodes operating at peak efficiency. It also disperses heat so efficiently that you’ll be able to bring your ambient room temperatures up. This drives critical RuBisCO reactions closer to their full potential for increased carbon assimilation.

With its unbeatable thermodynamic balance, the F1V ensures more cannabinoids make it to harvest. Using the best grow lights for indoor plants guarantees the best-quality harvests for years to come.

Make a Friend
Out of Heat

Unlike obsolete plasma grow lights the F1V has no massive 'infrared spike' hidden on the far ends of its spectrum. This means drastically less heat radiating down on your canopy.

Less AC Less AC

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.

Less AC 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.

Less AC More Bud Growth

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

Less AC More Cannabinoids

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

Less AC More Terpenes

Terpenes are also heat-sensitive compounds and degrade at higher temperatures. Enjoy some of your best terp profiles ever with the F1V!

Less AC Higher Harvest Quality

More cannabinoids and better terpene profiles means you'll enjoy some of your best harvests yet with the F1V. Experience the results of the best full-spectrum LED grow lights with the F1V.

Made for Damp Environments

Every F1V is custom made to order, which means we build them to suit the specific parameters of your cultivation environment. The F1V 600W is typically suited for vegetative growth in vertical environments. On the other hand, the F1V 1000W performs best in flowering vertical environments.
