It's an experiment. You may be right, that "limping along" is what
we want for slow, steady production. On the other hand, perhaps
the choice is between limping along for x timeperiod, or adding
nutrients and flying along for the same x timeperiod. My vote
would then go for flying. So I'm trying it out. Worst that can
happen is that I have to use that sludge from the bottom of the
bottle to start a new culture sooner than I would do otherwise.
Has anyone else already tried this, and can tell us what happens
when nutrients are added?
