Humans are curious creatures by nature. We’re hardwired to explore and discover. Curiosity is how we continue to learn about the world around us. It is what fueled us to space, the moon and Mars, and it is what is pushing
to become a “next-gen” cannabis company.
Based in Portland, Ore., Pruf operates as part cultivation business and part research and development (R&D) lab. It benefits from being a subsidiary of GroundWorks Industries, a vertically integrated company with investments in production (Pruf Cultivar), retail (Serra, Electric Lettuce and Farma), distribution (GW Distribution), processing (GW Processing, GW Workshop) and services (GW Services).
Being part of the vertically integrated business guarantees shelf space for Pruf’s products in Oregon’s competitive market. More importantly, though, says Groundworks Industries COO Karlee Eichenberger, “it’s something that helps us provide the right amount of depth to the conversation we’re trying to have [with customers].”
That conversation is quite advanced: Pruf’s product labels and in-store information cards go beyond strain names and THC content to include extended terpene and minor cannabinoid details—a point of pride for Pruf’s Director of Production Science Jeremy Plumb.

A long-time cannabis activist and researcher whom Willamette Weekly once qualified as “the smartest guy in the room,” Plumb leads Pruf’s R&D projects. He is most passionate about the cultivation environment’s impact on a cultivar’s cannabinoid and terpene profile (aka phytochemistry). “I live to find correlation between changing environmental conditions and various phytochemical outcomes,” he says. “To make the connection between genotypes and chemical phenotypes is just as exciting as it gets.”
Plumb’s passion for discovering, creating and expressing exotic phytochemical profiles stems from his past experiences. He was a patient advocate in the ’90s, when the AIDS epidemic was ravaging California communities. Having already been inspired by the work of cannabis pioneer’s such as Chris Conrad, Mikki Norris, Lester Grinspoon and many others, he eventually had the opportunity to watch Dennis Peron interact with patients at his famed San Francisco Cannabis Buyers’ Club. Seeing patients receive the standard of care offered by that collective, as well as by Women Advocates for Medical Marijuana (WAMM) in Santa Cruz, galvanized Plumb to study cannabis.
When he moved to Portland in 2000, he became involved with the medical cannabis program. After a subsequent encounter with Sunrise Analytical founder Pat Marshall, he began conducting chemical analyses of his own plants and other medical
