How the Secret Greenhouse Of Survival Works!

Come inside of our sustainable insulated greenhouse in the Secret Garden of Survival. This greenhouse allow us to grow food 12 months of the a year, with no supplemental heat source due to the design and construction. Our planter beds are made of reinforced concrete that acts as a thermal mass to store heat from the sun during the day, and give off heat to keep the building and plants warm at night.

We use recycled gray water from our home to water the plant beds and the heat from the day, heats up water in a pipe system, that gives our home hot water all year round.
