Discover the steps needed to determine if protected culture is a good fit for your business with considerations for funding, constructing, and manage a high tunnel or greenhouse. This course is good for people considering or already maintaining high tunnels or greenhouses as the instructor has two decades of experience and welcomes questions from the group.
