Optimal Bubbles per Minute (BPM)
I am having trouble finding in the Search's what the optimal BPM is... right now I have 2 2L bottles going and am getting about 1 bubble every 4.5 seconds.. which is about 13-15 BPM. The culture is only 2 hours old, so maybe it will speed up.. but not sure if I would want it to anyway!
Also, is the BPM a good measure of when the cultures need to be shaken or re-done? I would assume yes... so what is the range I should aim to keep it at?
And this is on a 50g.
