A licensed cannabis operation in Parachute, Colorado has deployed a six-duck workforce as its primary pest control solution, part of a broader regenerative agriculture approach that eliminates synthetic pesticides.
Jimmy and Michelle Brinkerhoff run Edun's cultivation facility using Korean Natural Farming methods—a soil-building system that relies on indigenous microorganisms and layered living soil beds. The ducks, named SaDIVA, InDUCKa, and HIGHbird among others, patrol the grow beds consuming common cannabis pests including fungus gnats, aphids, and spider mites.
The approach represents a growing trend in cannabis cultivation as operators face increasing pressure to reduce chemical inputs. Colorado's regulated market requires extensive pesticide testing, and products that fail testing must be destroyed—a costly outcome that has pushed some cultivators toward biological pest management.
The Korean Natural Farming Method
The Brinkerhoffs' system goes beyond the ducks. Their facility uses living soil beds constructed in layers that mirror natural soil composition, with microbe-rich teas brewed on site to support plant health. Aloe vera serves as a natural moisture retention agent.
Korean Natural Farming, developed by Cho Han-kyu in South Korea, focuses on cultivating indigenous microorganisms rather than importing commercial amendments. The practice has gained traction among organic farmers worldwide but remains relatively uncommon in commercial cannabis due to the labor intensity and learning curve required.
The duck integration adds another layer to this biological system. The birds work the soil surface, consuming pests while their droppings contribute nitrogen and other nutrients back into the growing medium.
Market Context
Colorado's cannabis market generated $1.5 billion in sales in 2023, but operators face compressed margins as wholesale prices have declined roughly 50% since 2021. Cost-cutting measures that maintain product quality have become essential for survival.
Regenerative agriculture methods can reduce input costs over time, though they typically require higher upfront investment and expertise. The approach also appeals to a segment of consumers willing to pay premium prices for sustainably grown cannabis—a market niche that some cultivators are targeting as commodity pricing pressures the broader industry.
Edun's facility in Parachute, located in Colorado's Western Slope region, operates in a less saturated market than the Denver metro area. The town of roughly 1,100 residents sits in Garfield County, where several licensed cultivation operations have established facilities due to lower real estate costs and available industrial space.
Scaling Biological Controls
The use of ducks and other biological pest controls raises questions about scalability. Large commercial operations growing tens of thousands of square feet of canopy would need substantially larger duck populations and more complex management systems.
But for small to mid-sized cultivators, integrated pest management using animals offers a chemical-free alternative that aligns with organic certification standards—though cannabis cannot currently receive USDA organic certification due to federal prohibition.
Some cultivation facilities have experimented with other biological controls including predatory mites, ladybugs, and nematodes. The duck approach is less common, likely due to biosecurity concerns and the additional labor required to manage livestock alongside cannabis plants.
What's Next
As cannabis markets mature and consumers become more sophisticated, cultivation methods are likely to continue diversifying. Regenerative agriculture and biological pest management may capture a larger market share if producers can demonstrate consistent quality and yields that justify premium pricing.
The Brinkerhoffs' operation in Parachute offers a test case for whether Korean Natural Farming techniques and duck-based pest control can compete economically with conventional cultivation methods in Colorado's competitive market.
