Cold Frames

Cold frames are simple unheated structures that use solar energy and insulation to create a micro-climate. These warmer conditions allow to expand growing season in spring and fall.

Our six cold frames are located next to the November Greenhouse facing south. They were designed and built by our Farm Staff. Cold frames allow us to plant cold weather crops as early as six weeks (end of February) and to continue harvesting late in the season up to the end of November.

Planting and harvests are recorded in order to document their production and crops diversity.  

In 2018, several type of crops grew successfully including arugula, salad greens, fennel, radishes, hot peppers and herbs.
