“My yields under SpecGrade have been 75 g to 135 g per sqf per cycle, primarily in the Clone-to-Flower method in the SAEF system.”

“I am getting 13-18% more yield than Gavita and 3%-6% higher terpenes.”

“I am totally blown away by the build quality of this light. I work in pro AV mostly and this thing resembles a high-end amplifier installation more than an agricultural product. My plants are absolutely loving it and it’s made temp control so much easier.”

His & Herbs

“Here are the latest test results under the spec grades. We some some very high THC content numbers and are very impressed with the end product coming out from under your lights.

The cookies and cream strain performed very well with some of the highest THC content our growers have seen so far.”

Evan Kaplan, Project Analyst His & Herbs California

“For one of our Pennsylvania clients our Hybrid Tech engineering team once again provided an analysis of multiple lighting solutions that indicate that SpecGrade as the appropriate provider.  After 2 years of operation once again proven to be the best in class cultivation lights currently on the market.”

“SpecGrade LEDs is a well-established LED company in applications of high power LEDs with good thermal management system (for highway lighting and stadiums) and recently entered in horticultural market. I collaborate with them to have custom designed LED lighting systems for various crops.

I am very grateful to you and your team for the capacity of your R&D to develop LED lighting, design appropriate heat management technologies, and evaluate the performance of lighting. We had finished our successful year of growing various crops in greenhouse with your LED lighting, including strawberry, lettuce and basil. I am particularly happy about the plant performance under LEDs and look forward to our second crop year starting soon.”

“The Extra – 60 is currently over a mother plant in veg that has just exploded since being underneath it.

The Flora Series 5 bar is over some freshly transplanted plants that seem to be enjoying them.

The Flora Series 10 Bar is over 2 of our larger mother plants. The spread of the 10 bar is phenomenal for full canopy coverage. Its part values are a little lower than I would like for mother plants but it is a big plus that the plants can grow right into the light and not get much damage. This would also be a fantastic light for the 4″ and 1 gallon potted plants in the racks.”

“ …we couldn’t be happier with our relationship with SpecGrade. Rick & Doug have been excellent partners in our new grow facility. They have reacted quickly to our requests and have shown us new products that are increasing our yields.”

Claire Hobson:
“Our licensed grower in Cleveland (Ravenna), Ohio is using our Verta-8, Verta-4 and Linea series LEDs in his veg, mom, clone rooms and in our flowering greenhouse. We have tested their Linea’s and want to change out every HID fixture.”

“Specgrade’s Verta-8 is leading the way on electric efficiency, balance efficiency, superior/robust physical design as well as it is easy to set up. It is producing 70 grams per sq. ft. and above…high quality, top shelf of dry flower.”

Nelson Lindsley Agriculture Consultant California

Habitat Life

“I am only about half way through the first flower cycle. The lights are performing well, I don’t have metrics to share since we haven’t gone through a full cycle yet. I can see that the plants are bulking appropriately and seem to be right on cue.

I am running at an extremely reduced load on my HVAC as well because this fixture runs so cool and efficient. The overall quality of the lights are amazing… “

Laine Keyes Habitat.Life Chase, British Columbia (Canada)

Todd McCormick

“I have been growing cannabis since 1984, and I have been growing under LED lights since 2015 …In the past year I have gotten to use the Verta-8, which is dimmable and very well-built; and have a more even coverage over the canopy with the LEDs laid out in bars. I also favor the Verta design for both air circulation and the ability to look down into the canopy from over the light to spot problems. Overall I am so very impressed with the dimmable Verta 8, that I am planning to replace all of the lights in my mother room to 24 Verta-8’s, as the build quality and the dimmable ability just can’t be beat.”

Todd McCormick Grower San Francisco

Maui Grown Therapies

“We’ve tested the Verta 8 fixture side by side with Fluence SPYDRx+ several times. The spectra are about the same. Negligible difference in product quality, but we prefer the Vertas for the following reasons: increased yields, sturdier construction; better dimming solution; driver consumes less power; diode boards can be unscrewed and replaced with new ones, obviating the need to purchase a new base fixture; better customer service; better price.”

SpecGrade LED’s Verta 8, Linea, and Flora 5 have all produced outstanding results in our cannabis research plots. Not only do they provide a comfortable environment for the grower, but the lush growth of the plants is simply stunning. Under our methodology, the Verta 8 luminaire consistently yields in excess of 70 g/sqf of dried flower per 6 to 9 week cycle, depending on the cultivar. The quality of the cannabis produce matches that of the luminaires themselves, which are industry leading and best in class. Our cannabinoid and terpene levels match or exceed anything we have witnessed grown under HID, competing LEDs, and even sunlight. I can safely recommend these luminaires to any and all serious cannabis growers looking to make a purchase that lasts a lifetime and performs like a dream.

In summation, I highly recommend SpecGrade LED for your horticultural lighting needs in both indoor and vertical cultivation facilities as well as greenhouses. I believe you will fall in love with these white powder coated, solid and sustainable fixtures just as I have, and you love having an attentive and responsive lighting partner even more.

“Hi Rick…The Verta-8s seem to be doing well. We just pulled down 8lbs of dried bud from under a section with them, which is 56.8g/ft2.

“ …overall I did think it was a great light, and I got the same results from HPS and used 40% less power to achieve those results…light was very solid and well built, and came with useful mounting supplies (not all companies provide this)…produced great results for quality…yields were on par with expected when compared to a single ended HPS at 1000W.”

” I have been working in the cannabis industry for the last 12 years and have yet to find a fixture that has more versatility, a better spectrum, and is more durable than the Spec Grade VERTA series. Its everything you could want out of one Fixture!”

SpecGrade is quickly making its way to a list of the well-known and like Cannabis LED companies. Their fixtures are well designed for vertical growing and very solidly built. No other lighting company I know offers a 10-year warranty and easy accommodations of the spectrum changes by swapping out solder-free diode boards. While many other LED companies expect and want cultivators to replace the fixture every 3-5 years. SpecGrade is selling hardware that’s made to last, yet designed to evolve.

“ I’ve tried many different LED & HID grow lights and by far SpecGrade’s Verta-8 outperforms all of them. I will never buy any other brand grow lights for my facilities.”
