A report here on the controversy over whether hydroponic, etc. ag is really "organic".
As I see it, it's a debate between the old-line organic affiliated with the food movement, who often (yes mom, thinking of you) romanticized family farming and producerism, versus the high-capital people who can fund hydroponic agriculture. Or, to put it another way: a contest between the "good" of naturally grown food and the "not bad" of unnaturally grown food which excludes all the bad 'cides.
Or, a third way: between the romantics and the rationalists.
