The important thing to remember is that it is the liquid part of the culture which we drink which is the most important part.
You have seen in my Kombucha experiment, that the KT liquid added to the sweet tea has itself the ability to produce another scoby on top, even if there wasn't a 'mother' scoby to start with. Both the liquid and the scoby contain all the DNA for the Kombucha culture to replicate itself. You have seen that ooglie splodges are quite common and I hope you have lost your fear of them.
The only thing to watch out for are furry-fuzzy growths on the liquid or the scoby top itself. This is mold/mould and can be poisonous.
The whole brew needs to be discarded if that happens. Mold/mould is avoided by adding a generous amount of acidic KT over the top of a new brew before covering the jar. You should use a dense-weave cloth to exclude dust and creepy-crawlies while allowing the brew to breathe.
Your jar needs placing in a quiet, warm spot away from children and animals or other wobbly disturbances. A new scoby will only grow if left undisturbed. Once disturbed it will not grow any further, but another new scoby will always begin to grow again across the top of the liquid.
Scoby growth on the top of the liquid and bubble activity are the sign of a well functioning brew.
