How To Know When Liquid Culture Is Done?

yup I’m looking at all my jars inoculated from the LC and they all look the same… a certain wispyness I feel like I don’t usually see… hmmm

another option is small shards / pieces of glass

was in a pinch a few weeks ago, making some LC and didn’t have any bolts or marbles or stir bars. Remembered this comment and used some broken glass.

its working great, all the LC with broken glass appears healthy, and it makes such a beauitful tinkling sound when you shake it :slight_smile:
