Having seen the inside workings of a local farming co-op, I can tell you that they they also do not necessarily grow their own food. Some produce is literally sourced from major chain grocery stores in town and resold with markup by the farmers at the farmer's market. To be fair, the sellers usually do sell some of their own produce as well, if it's in season, but some of them don't hesitate to also simply resell grocery store produce to bulk out their product offerings. (And frankly, the grocery store produce often just looks more fresh than the produce actually grown by the vendors themselves.)
