A cold weather greenhouse is designed to extend the growing season by providing a controlled environment for plants during colder months. These are built with materials that offer good insulation and often incorporate features like thermal mass, insulated walls, and tightly sealed joints to retain heat.
Some cold weather greenhouses may use passive solar heating by capturing sunlight during the day and storing warmth in water barrels or stone floors. Or, they may rely on supplemental heating systems to maintain a stable temperature. Cold weather greenhouses are good for growing hardy vegetables, herbs, and flowers during the winter.
