Wrap the edges with some perimeter heat to give those areas the boost they need. Extremely even and consistent heat is especially important in research and institutional greenhouses, and we know how to account for the heat loss found at the edges. Perimeter heat systems are also good for heating areas that connect spaces, such as hallways.
