Polyseed states that for "best" results to use seed within six hours of rehydration.  Holding overnight is obviously not recommended.  At one time they discouraged you from aerating it at all for it tended to grow undesireable organisms on the glassware, Delete Duplicates  in the tubing, and in the seed solution.  I am unsure what has changed in their formulation of the seed material since then.  Too fast stirring and especially stirring longer than an hour creates conditions in the flask which induce logarithmic growth of the organisms.  That is straight from the mouth of the owner of Polyseed just a few years ago.  Best results come from adhering closely to their instructions.



Thank you...nice info.
