Low labor, 1/2 acre, high produce farm, aka SHTF farm.

You may be an expert in growing [no idea] though it's weird to me you didn't look further into it on HOW.

For instance it makes sense how he can pull it off;
- churns over the soil with organic matter - hire a tiller for a day.
- lays down tarps to kill off the weeds and weed seeds
- puts down rows of weed mat, burns spaced holes where he's going to plant with a jig made of plywood.
- lays down drip irrigation
- plants appropriately
- uses greenhouses to deal with the colder temps in Canada.

The material costs ARE higher, which is the trade off with labor. Makes sense to me. He's probably 6A zone in Canada btw, plenty of ideas on how to deal with 'some' of the weather conditions you face, such as using low cost greenhouses to extend seasons.

Personally I still can't see how I can grow enough KJs in the 10x10m full sun area I have via veggies and I'm researching staples such as grains/legumes [soybeans] which can produce the needed KJs, protein, fats. Never the less the principles of killing weeds by covering with a tarp/silage tarp is brilliant. Lots of labor reduction. There's plenty of videos on no-dig gardens that utilize cardboard instead and allowing it to be eaten and composted right on the beds, though essentially the same principle. I've done enough veggie gardens to at least grasp the labor in removing weeds and having to keep on removing them.

In terms of water, he's got a bore/well there.  It's certainly an issue on production, though pretty sure commercial farms irrigate as required. If people were collecting rain water there's a good chance they'll have enough to water plants via drip and rainfall.  A little bit of solar and you've got your water sorted.  Don't see it as much of an issue, though that would really depend on people's specific problems.
