Looking to brew with multiple people on Labor Day, but currently only have one stir plate. Is there any harm in using a stir plate 2-3 days early, then letting it sit after having it on the plate for a full 24 hours? We'd probably shake it whenever we walked by it, but it wouldn't be continuous up until the point where we would pitch it.
Wasn't sure if there was a law of diminishing returns when making yeast starters. The other option is to use it a day early for one person, then have another one start it the day of brewing, then pitch the next day.
Let me know if anyone has had any experience (good or bad) with doing either option.
