Grow Pros Solutions is a grower-owned and operated manufacturer of high-performance LED grow lights specifically engineered for cannabis cultivation. Over 25 years of hands-on cultivation experience and direct control over product development gives it the deep industry insight needed to close the gap between performance and affordability for growers of all scales.
“By managing the manufacturing in-house, we can design and bring inventive products to market faster than anyone else,” says Chuck McKenrick, VP of sales.
One of the company’s most notable innovations is under-canopy lighting—a long-awaited solution in the cannabis community. Leveraging advances in LED spectrum tuning, waterproofing and energy efficiency, GrowPros made the lighting both practical and profitable. By illuminating the lower parts of the cannabis plant, previously underexposed and underutilized, growers can unlock the full potential, increasing yields by 30–60 percent and turning once wasted plant material into valuable output.
Leading the Evolution of Under Canopy Cultivation
Under-canopy lighting has been around since the pre-legal or black market era. But until recently, the technology to make it viable didn’t exist. The intense heat from traditional high-pressure sodium lights often burned cannabis plants and made narrow work areas hazardous for workers. Fluorescent lights lacked a full spectrum, weren’t waterproof and offered little to no return on investment.
Grow Pros took under-canopy lighting from concept to commercial success by engineering fixtures for the distinct challenges of the grow environment. For instance, unlike top grow lights that are typically installed once and rarely handled afterward, under-canopy lights are installed and removed multiple times per year to allow for pruning, maintenance, and harvesting access. Since this task is typically handled by junior staff, the fixtures need to be especially durable and easy to manage.
The GrowPros lighting was proactively designed to improve ease of installation, durability and user-friendliness.
To complement its engineering efforts, GrowPros also took the lead in making under-canopy lighting more financially accessible, not only by managing manufacturing in-house, but by proactively pursuing rebate approvals even before product launch. This ensured they would qualify in as many regions as possible. The strategic approach allows it to offer high-performing fixtures at significantly more affordable prices for growers looking to maximize ROI.
On the innovation front, it continues to push the boundaries of spectrum science. It was also among the first to incorporate 730-nanometer, far-red light into a fixed spectrum, a breakthrough that dramatically improves light penetration throughout the canopy. Integrating far-red light required precision. Too much can trigger a shade-avoidance response in plants, causing unwanted stretching or reduced bud density. Conversely, too little can induce a direct sun response, limiting lateral growth and slowing canopy development. GrowPros successfully dialed in the ideal amount, enhancing yield without compromising structure.
This breakthrough paved the way for developing the first dual-spectrum controlled, under-canopy lights—Under Canopy Four. These fixtures allow growers to independently control the 730nm far-red wavelength, which can promote earlier flowering. Some customers report flower site formation three to seven days sooner. They also shorten the overall flowering cycle and provides growers with more flexibility in scheduling.
The Under Canopy Three introduces advanced crop steering capabilities. With one-half of the wattage of the fixture emitting UV and high-blue spectrums and the other half focused on red and far red, cannabis growers can fine-tune the light output to enhance color expression, aromatic profile and cannabinoid development, all tailored to the specific strain.
GrowPros also offers cultivation consulting tailored to each grower's environment, goals and strains. The team helps clients fine-tune everything from light strategy, crop steering, facility design, spectrum planning and rebate optimization, ensuring growers get the most out of their investment. Involvement in some of the latest horticultural spectrum studies in collaboration with leading universities keeps its recommendations grounded in cutting-edge science.
Adapting Solutions for Real-World Impact
GrowPros' client-first approach is reflected in how they help growers navigate and implement lighting strategies that best fit their operations. In one case, a grower trialed dual-spectrum and fixed-spectrum under canopy lights. While the dual spectrum solution delivered strong results in a small-scale test area, expanding its use across a larger facility presented unexpected complexity. With a larger team involved in day-to-day operations, managing advanced spectrum controls became less efficient when scaled to hundreds of thousands of square feet of flower canopy. GrowPros worked with the client to pivot back to a fixed spectrum setup, a more plug-and-play solution that better suited the scale of the facility and its staffing structure. The client successfully streamlined workflows without compromising performance.
It also worked with a grower who had long relied on high-pressure sodium top lighting and was resistant to newer LED technologies. Rather than pushing a complete transition, GrowPros introduced under-canopy LED lighting that worked alongside their existing HPS system. The added light significantly improved lower plant development, increased total yield and boosted overall revenue. Encouraged by these results, the grower later replaced their HPS fixtures with full-spectrum LED top lights, achieving greater energy efficiency and yield improvements.
Empowering Growers with Scalable, High-Performance Solutions
GrowPros is entering an exciting new chapter. After five years of strong national sales, it is expanding rapidly into international markets with new distribution across Canada and emerging opportunities in Europe.
“We’ve continued to expand year after year, largely because we’ve stayed on the cutting edge,” says McKenrick.
From a technology standpoint, GrowPros is doubling down on spectrum crop tuning—the ability to tailor light spectrums precisely to a plant’s strain and stage of growth. New multi-spectrum controlled top lights are being developed to work optimally with the company’s under-canopy fixtures, creating a fully integrated lighting system that maximizes yield throughout the entire canopy space.
It controls manufacturing in China and is exploring American production opportunities to increase flexibility and resiliency as the company scales.
As GrowPros Solutions grows with intention, it continues to balance breakthrough innovation with real-world practicality. This forward-thinking yet grounded approach has made it a trusted partner for cannabis growers looking to maximize performance, efficiency and return on investment.
