Greenhouse Design

Join Stone Barns Farm Director Jack Algiere and Nexus Vice President of Sales and Northeast lead Jeff Warshchauer as they dive into soil-based greenhouse design during this full-day immersion course. It will begin by understanding your management goals and practices as farmers to optimize your costs during the greenhouse design phase. We will then discuss how to work with greenhouse designers, like Nexus, and what is involved during the greenhouse construction process so you can design efficient environmental controls that program ventilation equipment, water, and heating systems. What techniques are used during the construction and operating phases to maximize soil health and productivity? What are examples of companies and vendors that help with greenhouse design? Lastly, what per square foot capital cost can you expect and how do you optimize your management practices to payback this investment? All of these questions and more will be discussed during the course as we introduce the value of permanent, soil-based greenhouse designs to the community of beginning farmers.
