answer:Vegetables are still emitting gases (as they do when they are living), once they are harvested. So for max freshness, keep them breathable. Like in a perforated box or something. B/C keeping them in bags (so it’s not the moisture actually), keeps them exposed to the gases they create, which ripens them more quickly . . . (which is why if you want your fruit to ripen faster, you keep them in a bag!) So the key is air flow.
