I've been kinda busy. I've had a yeast starter (Wyeast 1056) going for over a week now (1L size, 1.040 OG). Nice and creamy yellow color, still got a small dimple in the top of the fluid.
Assumming the yeast are done eating all the sugars and have attained maximum growth and reproduction, am I harming the yeast by keeping it on the stir plate and aerating it? (Air only, no Oxygen).
