I work with some folks who have tried this technique and have had decent results with it. The wife and I were talking last night about planning next springs garden and we have started kicking around the idea of growing some of our herbs and greens (lettuce, spinach, arugula, cabbage) in bales. If nothing else just as a test to see how it goes.

Does anyone on here use this growth medium in their gardening? What do you grow in it? What kind of results have you had? What special treatments do they need?

Here is a link I have been reading from to try and educate myself, well to the extent possible at least. I am still in research mode and will add links as I find them.
