But if the cathode is rapidly plated silver, isn't this really not a
concern? Or maybe run a couple batches to get the cathode well plated,
and use the first CS batches for cleaning, or watering plants or the like?
Or are you saying that the copper hydroxide, copper oxide, or whatever,
would still be formed and released even after the cathode is well plated
with silver?

The hydroxide radical is released at the cathode. The hydroxide radical is
very reactive and will almost certainly react with the copper and zinc in the
brass producing copper hydroxide, zinc hydroxide and/or copper oxide and zinc
oxide. The only metals I know that can be safely be used on the cathode are
noble metals, maybe chrome, and high chrome stainless steel. The crome forms
a non-soluble conductive barrier on the steel surface when it oxidized
preventing further oxidization.
