"“Free software” does not mean “noncommercial.” A free program must be available for commercial use, commercial development, and commercial distribution. Commercial development of free software is no longer unusual; such free commercial software is very important. You may have paid money to get copies of free software, or you may have obtained copies at no charge. But regardless of how you got your copies, you always have the freedom to copy and change the software, even to sell copies."[1]
So yes, you can farm your own vegetables. But you shouldn't accept that you buy a potato without being able to plant it to make more potatoes. (Ironically, you should check back on that with Monsanto, though[2]).
