Hi, i been spreading wheat Spawn into new wheat. I been experimenting with different techniques.

I think i been having sucess , But some orange spots appeard on My mycelium.

Ive read that it could be mycelium waste or mycelial exudate/sweat. Can you confirm if it's okay or if it's contamination?

My mycelium is pleurotus ostreatus

Orange or brownish metabolites that appear to be present here are fairly common and harmless, but this picture also shows what seems to be green mold at the bottom of the jar, near your pinky finger. Maybe it is just an artifact of the photo, but it looks like contamination to me. You might get away with using the top part of the jar for spawning a mass substrate like straw, but I would not use it to make more grain jars.

Yes, thats an artifact from The photo. In reality theres no green or gray spots
Is there any way to avoid that Orange stuff?

Should i put My mycelium in The refrigerator now?

Thanks for The reply.

Not that I'm aware of, it's nothing to worry much over anyway.

The Orange spots started to grow and they are generating some complex , crazy and beautiful patterns.

It's like a living piece of art.

I would like to be able to control The generation of these exudates. Maybe being able to control it's color?
Maybe it would be Nice to create a mechanism that allows the micelium to life longer. Maybe a way to feeding them from outside when it colonized all The grains? And maybe using different substrates and stressing The micelium on purpose ?
