The Ohio Controlled Environment Agriculture Center (OHCEAC), in partnership with the Controlled Environment Ag Coalition at NCSU, hosted its 4th Annual CEA Conference: “Advancement of High-Quality Transplant Production Technologies under Controlled Environment" on July 16, 2025. This year's conference focused on transplant production technologies and their crucial role in enhancing sustainability and productivity across various crop sectors.
The conference was attended by 95 in-person participants and 48 online participants, including propagators, greenhouse/nursery growers, crop producers, technology providers, faculty, researchers, extension educators and students. Thank you to everyone who joined us and helped make it a success!
