Possible vermiculite stain? or contam?
    #17318784 - 12/02/12 02:32 AM (12 years, 1 month ago)

This is my jar a few days (4-5) after full colonization and a few tan yellow patches have formed.  I am concerned that this could be a contamination? or possibly some vermiculite staining? I've read that some of the pigments of the vermiculite can bleed into the mycelium, is this true? if so what does this look like:



the other side of the jar:



upon taking the cake out of the jar it smells really fresh and the patches seem like hardly anything other than pigmentation, went ahead with a dunk and forgot to take pictures of the cake before submerging unfortunately
Here's one of it in the dunk(not great quality but its underwater and in a Tupperware so yeah):

That doesn't look so good man. Wait on a second opinion.

It looks like metabolites to me. Do you use a heater or something like this in your incubator?

the jar had been incubating for about a month (not the greatest inoculation and as a result it took a while for the colony to fully spread out).  it was in a tub floating on top of a warm water reservoir fluctuating right around 86degrees F the whole time.

86F is too warm. That would explain the metabolites.

this is still fine to fruit though correct? metabolites won't affect the quality of the flush?
