Just got off the phone with my brother, I was nagging him about air presence for the roots to breathe, he's an engineer so I reckon he knows the stuff. The beads are about 12 millimeter in diameter if saturated with water. He explained to me that it is like stacking marbles, there will always be gaps in between because they are spherical so there will be air in between the beads, the larger they are, the more air will penetrate the gaps so I must take care not to let the beads shrink too much. But as far as active air circulation is concerned he thinks there is air to breathe but will not have sufficient movement to make any significant impact.
I pressed a PH strip into the beads turned out to be slightly acidic: 6.0 maybe because I put a drop of rooting hormone when I put water for them to absorb the first time around.
If the orchid is stressed because of being submerged should the unopened buds drop or turn yellow or will they still open even if the roots are rotting? Right now I had 2 buds open in 4 days the third one getting ready to open in about 2 days time.
