No I’m. It familiar w the underground greenhouse. Where are you roughly located? We’re in TX so aside from the arctic blast we are currently experiencing we can generally grow in standard greenhouses throughout the winter.

The egg laying chickens are a no brainer. Very easy and your family could easily survive on the eggs, an easy stored grain like rice, and some greens that you can grow. Combine those with fresh water and you are not a slave. Keep it simple and how to best accomplish those 4 things water, eggs, grain, greens and then you can get as extravagant as you want.

Just remember to plan ahead. We have planted 60 Apple/pear differing varieties so that different trees will bear fruit from late June all the way to November-December. These fruits can be readily eaten, canned/sauced or fed to farm animals (pigs). The orchard was started 2 years prior to our acquiring the pigs so we would have some supplemental food sources once they were here. The pigs will be kunekunes variety which are grazing pigs that came from New Zealand so they can actually be grown fully on Bermuda grass if you choose.
