RAH has it right. Grow what is best for your area and sell the excess to pay for the essentials that others can grow cheaper. I do the same thing with wood and woodworking. A small cedar shelf or unique piece of wood harvested from our land pays for the treated lumber and plywood I need. I have paid for all of my equipment this way, including the sawmill. I have done the same with jelly in the past. Collect all the muscadine grapes I can off the local roads and sell the jelly at the local farmers market.
