The underground heat exchange system, also known as a climate battery, offers a way for your solar greenhouse to become passive solar! When the temperatures rise during the day, the fan kicks on to store the hot air underground for later use. Once the temperatures drop below 50 degrees, the fan kicks on to raise the temperature and keep it stable! This system comes included with our Glacier passive solar greenhouse, and can be added as an upgrade to our New England and Homestead greenhouse models.



We teamed with Joel, who is one of Hometown Structures finest. He has been growing in the greenhouse for five years now. Listen as he describes the features of his greenhouse to give you an idea of what you can do!
