I'm only studying it right now. I'm a little dismayed that most of the online resoruces basically want to
sell you expensive "plans." My bug out property has ample land so I don't need it, but my wife would like
to remain in "the city" as long as we can and so its needed here if we are to enjoy growing our own food
and that's why I'm looking into it - not doing it - yet.
It is intriguiging to think one could produce all the vegetation one would need permanently on less than
40 square feet. At least one outfit as made the claim (actually 25 square feet I think).
