I watched a few videos online about how to create a mother SCOBY from scratch using the cultures from a couple bottles of GT kombucha. I went through the whole process today and have it sitting quietly waiting for my mother to form but I'm not sure how to tell when its done. I know its going to take a couple weeks but what do I look for to decide that its finished? I'm using a standard one gallon pickle jar, so do I measure the thickness of the SCOBY, or should I take periodic pH tests until the tea gets down to 3.0 and then call it done? Or follow some other method? In the videos they just say "ok, the mother SCOBY is done" but don't say how to determine that.
Lets leave our s**t where it is and go live in the woods.
