Our 42-foot dome is a kit made by Growing Spaces which is based in Pagosa Springs, Colorado. It was delivered to our site and installed in just one week on the prepared site. Our dome’s climate is managed by a Wadsworth timer that helps to regulate the low and high temperatures with the help of a climate battery. The climate battery was installed approximately 4’ deep under the dome where the air temperature remains a steady 55 degrees Fahrenheit. The large ‘tubes’ of the climate battery have an intake and outtake inside of the dome with fans embedded inside. In the summer, hot air is pulled into the climate battery and mixes with the cool air underground and gets pushed back up into the dome. In the winter, the cold air inside of the dome gets pulled into the climate battery and gets heated up and pushed into the dome. Supplemental fans and heaters help when there are more extreme temperatures to manage.
