So where does gardening end and farming begin? If you have a balcony with planters on, or 100 acres of wheat the distinction is easy, but for some people a couple of acres and a sign outside that says "Fresh Organic Vegetables for Sale" is
right on that line between the two. And it matters, because of how you think of yourself. My mother once worked in a place that had literally acres of greenhouses, yet they called it a Market Garden. Farmers can be gardeners too of course, but the outlook is different.
A lot depends on whether you sell your surplus or not, and perhaps if animals are part of the equation.
