Green String Farming approach

See my “natural wine” thread for more details.
Anybody familiar with the “Green String farming” approach? How is it different from organic/bio/sustainable farming?? Why isn’t it taking the wine world by storm like “natural” winemaking? Or is it just a Cline gimmick?

It strikes me as a term very specific to the “Green String Farm”, though from my very brief reading, the concepts seem in-line organic/sustainable practices elsewhere.

Makes me think of String Cheese Incident.
