paroxide and germination breaker

The hormone in rooting powder is one of the forms of auxin, such as
Indole Butyric Acid or Indole Acetic Acid. I don't think it will have
much of an effect on germination.
I have been told that hormone rooting powder should be bought fresh, and is
essentially GA. I have not used it myself.
