Ok I am going to take the plunge. I ordered my S/H stuff and should get it this week. The question I have is about the roots. I have some phals that have roots growing out the side slats and holes in the bottome of thier pots. The S/H method has a water reservior in the bottom of the pot. I would think that the roots would do great above the reservior but would grow right down into it. Sitting in the water don't they tend to rot and introduce the rot to the rest of the root or do they just stop growing down once they hit the water?
