I have real obstacles, like a need for resources I do not have, and knowing any change to a new location would be such investment that I would not keep trying other choices if that which I would come to was not what I would stay with. I want to be really sure, and the further away it is from my location in the US, the more critical I would be of it. This you have described involves much that has to be thought out, but really quite the way how I would want things where I would be. Where growing in a greenhouse is needed, enough space for all that would be needed should be thought of. There are things I do not think I would have thought of, like putting on an additional room to the greenhouse. Where anything growing wildly is edible that can be foraged, I would want to try each recognized while taking any sparingly, keeping any seeds that come with what is foraged to replant, and leaving enough for the wild plants of the ecosystems to still thrive. Without using crops, some wild growing plants that grow compatibly are useful for growing what will be needed among them. It should be clear I mean what will grow apart from inside a greenhouse.
