I've started making more starters because I'm beginning to use more liquid yeast. I have a stir plate on order and I usually make a 2l starter in a 4l flask. I chill overnight and decant the liquid because I don't want 2l of off-flavor liquid in my beer.
Pitching temp: Assuming it's safe for the yeast, does it matter that much? I don't have a wort chiller for my flask, so it takes a while to cool, even in an ice bath. Is pitching at 85-90 bad?
Fermentation temp: I usually ferment at room temp (75ish) rather than in my fermentation chest freezer (65 or less). I figure the starter finishes quicker and I end up with more yeasties.
Aeration/oxygenation: I have been oxygenating my starter, but will I still need to when I get a stirplate?
How long: How many days before brewing do you make your starter? How long do you cold crash it before pitching? So far, I've made the starters 3 days ahead of time and chilled overnight (12-18 hrs)
