# root cellar

## Core idea
To build a functional root cellar, you need a well-drained location, a stable underground temperature of 32° to 40°F (0° to 4.5°C), and a high humidity level of 85 to 95 percent.

Site selection: Pick a well-drained, elevated spot or a north-facing slope that avoids high water tables, septic systems, and large tree roots.
Build types: Choose between an easy in-ground container (like a buried galvanized can or plastic tote), a walk-in earthbag structure, or a dedicated basement corner.
Depth: Dig deep enough—typically 3 to 8 feet—so that your stored produce sits below the local frost line for steady thermal regulation.
