Great concept!
Are you open to a “Variation on a Theme”?
Similar set up as originally described, except that each group/person has to use the exact same number and variety of plants. (You make that list)
The object, then, is:
1)who can grow the most net calories (calories grown minus calories spent growing them)
and
2) which method(s) produce the highest yields compatible with permaculture philosophy.
Divide the prize (kick starter) money accordingly
Kind of like Iron Chef goes Permaculture.
I’d pay to watch that!
