Stir plate starter question

Ingredients
1

I’m using a stir plate on a starter for the first time, and was wondering if I will see any foaming or activity. Or just the spinning wort?

You will see some krausen form and the wort will turn milky color as the yeast multiply.

Cool, Thanks

You may or may not see anything. The stirring tends to break up the krausen, and a starter could ferment out overnight or while you’re away.
