I am thinking this mold on my child? If it is will someone send me a new mother?
That is what I thought....into the trash this goes. Anyone have an extra mother?!
Was it furry at all?
Why not cut around that section, submerge it in vinegar for a few days and try it again?
And from the looks of it, you could grow a new mother from a bottle of commercial to that big in a week or 2.
