    I have some onions in pickling vinegar, some in balsamic and some in “ white vinegar” as my daughter prefers those.

    Just been checking. Apparently white vinegar is stronger so more useful for cleaning stuff and whatever. It's great for cleaning chrome bathroom radiators
    Good for cleaning brake dust off alloy wheels tho....just sayin'

    I use organic cider vinegar (quite affordable when bought in larger amounts) for my pickles and chutneys. A much better flavour and gentler on the innards. 😋 
    Ok, let's agree: any good quality vinegar has it's devotees.  All better tastewise than white, spirit, distilled or acetic acid.  Ones innards (stomach ) are ±pH 1.5 (hydrochloric acid) so a mere ±pH 2.5 from any vinegar is unlikely to be significant in gentleness.  Perhaps in the mouth.

    I have been unable to buy pickling onions yet this year.  Last year they were also late.  My daughter said: never mind I will get them.  And came with round shallots.  3X the price and lacking the necessary bite.  This year she says she can get them at the local market.

    To revert to Germination.

    All seeds have tricks for initiating germination: moisture, daylight, fire, freeze/thaw, ingestion, time... to name just some.  What seeds respond to hydrogen peroxide?  The only seeds I have difficulty with are parsley.

    I don’t bother to sow parsley seeds, I buy a rooted plant from supermarket,  split it up, you get about 20 plants out of one pot. I do the same for basil, and root more cuttings in water. Not worth the bother of sowing the seeds.

    It would be interesting to know what the science behind using hydrogen peroxide on seeds is (assuming there is some and it's not just a daft "hack" that someones posted on youTube or some such place). I can't see how it would encourage or enhance germination. Maybe it's supposed to inhibit fungal diseases or seeds rotting before they germinate.
