OUR Mission

To advance the Controlled Environment Agriculture (CEA) industry by simplifying procurement for our customers, streamlining the path to market for manufacturers, and expanding access to top performing commercial horticultural products.



RMJ Supply has been distributing complex engineered equipment and supplies to the Controlled Environment Agriculture (CEA) industry since 2017.  RMJ Supply was founded by seasoned operators to reliably procure horticultural equipment and production inputs for commercial cultivation environments.


While leading the design of state of the art cultivation facilities, engineers and operators struggled to access premier horticultural equipment and products needed to buildout and fit out professional facilities.   Developing sourcing strategies, managing complex procurement processes, and managing multiple vendor relationships was consuming growers’ time and distracting focus from operational performance.  RMJ solved this problem by building a network of vetted supplier relationships to effectively centralize procurement for a group of facilities.  In 2019 RMJ expanded focus beyond equipment and began supplying consumables to growers, and has since expanded its catalog and developed solutions to meet the needs of top performing operators.


Today RMJ is the single source solution for at scale equipment systems, cultivation, and facility supplies. Our centrally located distribution center, deep operational expertise, strategic sourcing capabilities, and inventory replenishment solutions make us the trusted distribution partner for leading brands across North America.

Mike Kupferman

Founder & CEO, RMJ Supply

Mike Kupferman has played an active role in developing state-of-the-art cultivations across North America, South America, and Europe. His expertise lies in identifying and sourcing growing equipment and systems that drive performance in commercial crop production.

Mike began his career in Portland in 2004 when he launched some of Oregon’s first commercial medical cannabis cultivation facilities. He moved on to California to help owners in Humboldt County improve operations and optimize output while minimizing environmental impact.

In 2016, Mike led the design, buildout, and operation of Holistic Industries, Inc.’s initial 300,000+ square feet of cultivation in DC, MA, MD, and PA. During this period, he oversaw development of an additional 50,000 square feet of cultivation for a specialized private equity fund. Today, these assets serve as the cornerstone for several leading brands.

In 2017, Mike founded RMJ Supply to support equipment procurement for the projects he was involved in, naturally expanding the services to additional design teams and operators.  

Mike studied Renewable Energy Engineering and Automation at the Oregon Institute of Technology.
