A method of humidifying air within a storage and/or transportation unit for perishable products especially one having air circulation provisions, such as a sealed marine refrigerated container, but without limitation to same, by introducing into the unit a water absorbing agent replete with water. The water absorbing agent may be introduced in the form of loose granules, or contained within a water permeable bag or impregnated within a water permeable substrate. Preferably, air is circulated over the water containing agent to maintain the humidity in the storage and/or transportation unit.
