At the moment Im allowing a little root time for my clones (root riot is the medium of my choice) before I transfer them into the "4 Pot Atami Wima system" in which Ill be using clay pebbles. But regarding the system I only have one question which is: How is it that the water from the drip tubes & stake get to all the roots which are growing in different directions when the water dripper is constantly placed in one area in the pot? Wouldnt the thin vertical stream of water from the dripper travel directly downwards as the clay pebbles do not absorb the moisture?
