The term "ion cloud" has the quotation marks because that's the common
language used.
Actually, it's a particle cloud.
Ions are too small to see...too small to reflect the visible wavelength
of light that you CAN see.
Plate out would be like a silver spot on the container due to the
'particle cloud' coming too close to the side r bottom as it follows a
conductive track from electrode to electrode. Some oxide plate out will
generally be apparent as a black spot too. Sufficient stirring eliminates
that effect. Excessive stirring seems to make it worse but more evenly
distributed. I think that it, like the yellow deposit is also an inertial
thing but from a different angle.
The yellow deposit left of the container that vanished when exposed to
H2O2 is 'sorta' like plateout but rather than being made by electrical
action [under electrical direction?], I think it is actually an inertial
collision effect of large particles inpacting the container sides. It
doesn't appear till the yellow batch of CS is left in the container for
some time.

Actually, the black film that collects on the anode and cathode has
been identified by others as silver oxide. Now, silver particles and
silver oxide are both black, and both conduct electricity. These
people are much more competent than me, so I trust their
identification as silver oxide.
But the mist that streams away from the cathode may be something
else. Ken (Ode Coyote) calls it an "ion cloud". This seems
plausible, but why doesn't it dissipate due to the ion charge?
Normally, when I got the mist with any of my previous processes, the
solution turned yellow and plated out. Coyote Enterprises has some
excellent photos on his site showing this. There is a picture of the
plateout at the bottom of this page. Click on the link after the
phrase "Eventually, it sticks to the sides of the container."

Here is a beautiful sequence showing the mist dissipating after
thermal stirring is turned on:

I get the same kind of mist with the ULVDC process without stirring,
but it doesn't seem to want to plate out.
I was sure the last batch I made with a 9V battery and a 51k series
resistor would plate out, since it generated a great deal of mist.
It is a bit turbid, and the salt test shows it is quite strong, but
there is no sign of yellowing. In fact, none of the batches I have
made since I started the ULVDC process have shown any sign of
turning yellow and plating out. The salt test show it keeps the same
strength as it had originally.

This is worth a bit more explaining. The electron would quickly hit
an ion and neutralize it. So the lifetime of a free electron is very
short.
