Early spring presents a challenge for farmers in the Mid-Atlantic region. Although many seeds need to start germinating, cold nights can lead to crop loss. Seeds germinate best under controlled conditions (e.g., temperature, humidity, light).

The goal of this project was to provide bottom heat to the plants. We used lumber and foam insulation to frame two large boxes spanning the length seedling tunnel. We then installed roof de-icing cable in the box and covered the cable in sand. The heat from the cable warms the sand, which serves as the base of the table for seedlings. Although this helped us get through our first two years, we are currently researching a better long-term solution.
