Build a Basement Root Cellar

Storing crops in a passively cooled basement root cellar is one of the most efficient ways to preserve food.

Cellar Vents
Traditionally, this cold room was an underground space built under or near the home, insulated by the ground and vented so cold air could flow in and warm air out in the fall. Then when winter temperatures arrived, the vents were closed, and the cellar stayed cold but not freezing.
