The best thing about this sort of farming is you get ready access to heirlooms basically whenever you want thanks to how many indeterminate varietals there are these days (if you have greenhouse or no frost in your climate zone you can have a fruit bearing tomato plant at pretty much all times). Occasionally I can get an heirloom in the grocery store but its a toss up what exactly it will be or if its even available at the time. Meanwhile I can pick out of the catalog some very bizarre looking tomatoes or other plants, grow them up before long, and in a few square feet end up with more of these heirloom tomatoes (that might be sold for like $5 a pound normally) than I could ever know what to do with. I can also grow various different herbs that are normally tricky to source, e.g. thai basil that can't be found outside asian grocery stores. Plenty of these heirlooms would be impossible to get other than growing them yourself because they have characteristics that make commercial sale a nonstarter: e.g. my heirloom tomatoes basically cannot be stacked up and sold in a market stand because they are sometimes larger than grapefruits, aren't very sturdy like perhaps a roma tomato is, and will crush themselves.
