It depends on which definition you want. If you mean the government definition, it is certainly organic. If you mean the definition as it was envisioned by the people credited with the founding of the organic gardening movement, it certainly is not. Go forth and look up "Organic" to find the principals, then dig down to their particular WP pages for the cites. It's all in there.
Organic gardening, before the corporations got their hooks into it, was about cyclical systems involving local food production and soil health intertwined with community health. There's not even any soil here. This is not organic gardening, although it may be Organic(tm).
