Currently there is no definitive answer i can give you for harvest/product storage, as we have not been told, the criteria varies between the amount stored and how many different types and sizes stored, but you will receive a warning pop up which tells you when you are nearing it's capacity advising you to use or sell some of the produce.
ty for the quick reply, i have gotten no pop up, but fish i bought at the market today did not go into my storage, nor did the ingredient gifts i was sent....pfft!
