Should potatoes be in the dark?
Potatoes do best in a cool, dark room with lots of ventilation. This keeps them fresh and firm and helps prevent greening. Greening happens when chlorophyll builds up under the peel. It is associated with solanine, a bitter, toxic alkaloid that can make you sick if you eat too much of it.
Do potatoes grow better in light or dark?

Can potatoes be exposed to light?
Potatoes will often go green when they’re not stored properly and they’re exposed to light.
