Very good article sluggo, that's the kind of information I was looking for.

So, Steve - the ebb and flow of pressure in the plants' roots is enough to slowly turn the substrate? I would still think that worms / snails would help bring more nutrients / oxygen to the depleted areas around the roots regardless of the guttation or O2 transport.

More supplemental O2 to roots = Better?
