About Us

After more than a decade in scientific development, Tropos Technologies is proud to showcase Wheatfield Gardens as the first-of-its-kind operating greenhouse — one that solves the huge climate control problems that have prevented other greenhouses from locating in most areas of the United States and parts of Canada. Today, this fully operational commercial greenhouse, located in a traditional “no grow” climate zone near Buffalo, NY, generates on-site power and precisely controls heating, cooling, humidity and CO2 to optimize healthy plant growth and development — year-round. Tropos is working with leading universities at this breakthrough greenhouse, refining best practices and steadily building on this innovative technology.

Team Bios


Arnold is Chief Financial Officer for Tropos. He brings more than 45 years of experience in energy, finance, investment banking, and corporate leadership. He is based in Jacksonville, Florida.


Paal is Founder/CEO of Tropos Technologies LLC. Tropos was created to enhance the efficiency and sustainability of greenhouse production company Wheatfield Gardens, where he also serves as president. Wheatfield Gardens is comprised of a fully operational 12.5 acre hybrid greenhouse/indoor farm near Buffalo, NY.

The two companies’ common parent, Power Greenhouse Integration LLC, acquired and reconstructed the greenhouse to serve as a pilot demonstration site for the patented controlled environment agriculture system. At the same time, the facility serves as an active commercial enterprise, growing leafy greens and herbs for local retailers, schools and restaurants. Significant Wheatfield Gardens buyers have included Tops Markets, Eden Valley Gardens, Edible Gardens and Desiderio Foods.

In December of 2017 Paal guided a successful application process that led to Wheatfield Gardens becoming a research partner with the New York Department of Agriculture and Markets to help develop industrial hemp as a viable specialty crop for greenhouse growers in the state. Today, Wheatfield Gardens is the state’s largest indoor grower of hemp for CBD.

Paal is an Advisory Board member for controlled environment agriculture at Cornell University’s College of Agriculture and Life Sciences and is a USDA Advisory Board member for CEA workforce development. He holds a B.S. in chemistry from the University of Maryland.
