I'm new to kombucha and this is the 2nd out of three attempts to have to be thrown away because of mold. It's very discouraging because I don't have access to an endless supply of free scobys to use after I have to throw each one out. Is there any known way to prevent this? I guess I could try a different room but this one is relatively traffic and light free. Otherwise I'd have to carry the open jars up and down stairs which just seems like an accident waiting to happen.
Also, I'm about to start some Jun, which requires large amounts of raw honey which is really expensive and I don't want to start it if I don't know how to minimize the risk of it developing mold.
