This works best for when you don't plant Blueberries or things that have multiple harvests with one plant. ***That way, they will be fully grown on the 1st of Autumn and all you will have to do is to harvest everything with your scythe for some extra money and plant your Autumn crops right away without spending any energy at all. The fertilizer from the previous Summer will also stay there - saving you from spending too much money on fertilizers. *** As well as saving money, you won't have to water (if you have sprinklers) and Hoe everything on the first of Autumn; so use that to your advantage and go on a fishing or mining trip! Keep in mind that this doesn't really work with bushes or continuous crops like Blueberries since you'd have to pickaxe them all and replant - way too much work. ***
I came upon this by accident but I decided to transfer all the food in my fridge in a chest as I needed more space. There was already a lamp beside my fridge but conveniently I was able to place my chest within the lamp and use it as normal.
