Potatoes enjoy a chill (but not too chill!) environment. Between 40-45 degrees is the optimal temperature—any colder, and starches will begin to convert to sugars, which is why it's best to avoid refrigeration.
Darkness is also crucial, as exposure to light increases the buildup of chlorophyll and solanine, an alkaloid that can be toxic. And while the terms "cool" and "dark" are usually accompanied by "dry," in this case, humidity is a good thing—potatoes enjoy as much as 90%.
