With hydroponic methods, nutrients are given to the roots in a state that is immediately available. With organics, you rely on the processes described in my Soil Notes that I linked. Think of it as going out to eat vs cooking at home. When you cook at home, (Organics) it takes a little longer to eat, because you must prepare the food to be edible. When you dine out, it is much faster because the food arrives in a form you can consume immediately. Of course people who eat out a lot are larger (Higher Yield) but not necessarily healthier. (Organic Taste)
I won't be pulled into a Hydro Vs Organics debate, because I feel both have their place. If I'm entering a cup, Organics. If I'm trying to grow a lot with a little, Hydro.
