I like to put wine corks stacked vertically (side by side) in the bottom of the pot and then use large grade bark for the rest of media...
wow, that's a great idea for the plants... but just imagine, some of us would end up attending the AA meetings after so much wine and the worst is that we will not be allowed to say: "Hello, My name is XXX, I am alcoholic, but did it only for the sake of my chids!"
