I have tried to get my kombucha brewing going for about half a year now. It grows mould over and over - about every 2. time. I have sterilised my glass jar in the oven, tried different covers - paper/ washed fabrics. I have tried different teas and different places in my house. My scoby is quite small, as I have tossed out so many... I also have tried to pour in more than 10 % of starter to keep the Ph level lower. Nothing seems to keep the mould out.
Many years ago I made kombucha in the same house, the same jar and even the same room in the house ( dark, not too hot) and I never had any trouble. Of cause it is another scoby, but the friend I got it from, has no problems with her brewing.
I keep a hotel and take new mothers and starter from there when my brew grows mould and has to be tossed. Could it be that my new scobys are too small? My hotel does not grow mould. Some here said one could use foil to protect the brew from mould spores coming inn, but then I would have no oxygen and would not grow a new mother?

have not got a Picture at the moment. I have made good batches from the "hotel", but maybe I should ask for a new SCOBY from my friend. I will try the loose foil tip and keep it in my warmest place
