Pics of substrate in jars.... contam?
    #18734261 - 08/20/13 08:50 PM (10 years, 5 months ago)

This is my second attempt after a failed first.  I would like some input from some more experienced and knowledgeable minds.

The jars are pints, and I now know that is a big no-no.  Two of the jars have stalled and I am at a loss.  Do I keep them and try to fruit or just toss them?

I am not sure there is some cobweb mold or what.  Thanks in advance!

Can't see anything wrong in your jars really.. (though the pics are not the best ever and I'm assuming the green tint is from the camera)  there's some myc piss (metabolites for NAH :wink:)  in the last pic.

Your biggest issue is going to be that they are not wide mouth jars.  How do you plan on getting your super sized cakes out?

Okay then you're good, doesn't look like contam in that picture. If you are sure that those jars are stalled than you can take them out, cut off the uncolonized section, toss it, dunk, and birth the colonized part of the cake.

Quote from MAIA:

"Myc piss is a byproduct of myc metabolism and mostly not a problem. The patches of piss can be a problem because it's easier for contamination to settle and germinate. Therefore, if mycelium continues to grow, don't worry about it, but if growth stalls and the bottom of the jar never gets colonized, that could mean contamination."


Should I be making it a concern to clean off the myc piss after I birth or do I have the green flag to dunk immediately?

Mycelium does not urinate, does not have a bladder, and there is no such thing as myc piss.  Why this horrible disinformation persists after we've known for over 50 years that these liquids are antibiotic and released in response to bacteria is beyond comprehension.
Next time you get sick, ask the doctor for a myc piss shot instead of antibiotics and see him look at you like you just bumped your head or fell off a turnip truck.
If your grains are infected, there will be metabolites.  If you've colonized at above normal room temperature, bacteria has been stimulated and thus the metabolites.

It's not even a waste product, and people who call it piss are ignorant.  The liquid is excreted to help break down the substrate, and in a different formulation is produced to fight contaminant molds and bacteria.  These are the products antibiotics are made of.

Cool thanks for clearing that up.

My temp has been between 76F to 80F, so I am going to lean towards contams.

The metabolites fight contamination, so is it safe to assume my jars are contaminated? Or will the metabolites be enough to save the cake?

I came across this thread and to clear things up, RR is 100% correct about this issue. There's no such thing as "mycelium piss" in the explicit sense. It was used for some time as a jargon. It stick for a while but I'm glad it's not used anymore because it can confuse people.

It was considered "piss" because it's a secretion. That's all.

The relationship with contamination is quite simple. Liquid accumulation (any liquid) can stop colonization and the substrate can be colonized by something else. But if everything is sterile, has it should, you shouldn't have any problems.

Hope that clear things up.

Higher temps may cause metabolites I believe
