3. Onion cold storage requirements (0°C and 65 to 70% rh)

A comparatively low relative humidity is essential in the successful storage of dry onions. However, humidities as high as 85% and forced-air circulation also have given satisfactory results. At higher humidities, at which most other vegetables keep best, onions develop root growth and decay; at too high a temperature, sprouting occurs. Storage at 0°C with 65 to 70% rh is recommended to keep them dormant.
