So I keep running into the same issue over and over again while I'm trying to plan for when I am finally able to get land and start my off the grid lifestyle: I cant seem to figure out how much land will be needed for growing food. It's pretty much the only thing I don't have at least a vague idea about. If it was just me, I could get away with a small garden, but I'm looking at possibly having a decent sized group of people with me, ranging from 10-20, depending on how things work out. I would want to grow a wide variety of edible plants, ranging from wheat and corn to the smaller normal garden foods, the wider the variety the better really. I've even been looking into green houses so I could grow more tropical plants. I understand how irrigation works and the various types I could use, but still no idea how much land I would need to make sure that I could feed the myself and the people with me. For now I am looking for plots of land that are 20+ acres in size (would rather have more than I need than not enough), but still no idea how much of that would need to be used for farming.
