Any way to tell if wbs jar is contamed at 100% colonization?

Ok so im messing with agar atm but have three wbs jars that just finished colonizing.
Last grow went bad due to bad spawn, had little white specks in jars last time i believe thats yeast infection but not totally sure..
Is their anyway i can check these jars other than opening them or looking for contams visibly because i see alot of rhizmorphic growth but im curious if theirs another way other than g2g them an hope for the best.. They lookn fine but since the last grow looked ok im nervous

camera is broken since i dropped it.
Its a classic 100% colonized wbs jar completely white with little rope style growth forming (the good kind) no visible sign of contam at all.

The only way to check for contams without opening is by looking at them. Once fully colonized the spawn is fairly contaminate resistant. Are you mixing with a properly pasturized bulk substrate? Without pics you will have to use your best judgment. Look at the contamination link under general cultivation. It has photos of the most common contaminants.

Before spawning it, crack the lid and give it a good smell. If it has a slightly sweet smell, then there is probably bacterial contamination of some sort. If it has that fresh mushroom smell, then it is most likely healthy spawn and would colonize well.

Right on ok. I plan to g2g this jar to others for spawn. I herd somewhere if you break it up an let it recolonize that is one way to see if its ok. smell is always the number one way to i do believe.
Nothing visible so i guess here goes nothing lol

Most of time, yes, but there's always a possibility. That's why the smell test is a surefire way to know for sure.

Oh dear lord no. I'll get a quote from when I had this debate awhile back. There's a big difference between fully colonized and cleanly colonized.
Quote:
Mad Season said: Well there's a difference between colonized and cleanly colonized.
This is colonized: 
Lots of members have noticed cobweb and trich from jars that look like this or better. Wet spots are bacteria. Not wet grains or wet spots. To colonize cleanly is the hardest. I had to change my pc times to 2 hours to reduce it.
This is (ALMOST) cleanly colonized, that's how hard it is to have it completely clean. This isn't even completely clean:

This is completely clean spawn:

Anyone who's done this for awhile will testify this is the hardest part of the hobby and is what will dictate the success or failure of bulk.
All those jars had a mushroomy smell. A miniscule amount of bacteria will get overpowered by the mushroom musk. Especially if it is covering the surface

Wow I never knew grain could contaminate that easily, my understanding was that 100% fully colonized mycelium could overtake any hidden contaminates once mixed with properly pasteurized substrates, at least most of the time.
I've had jars that looked to be bacterial because of wet grains sticking to the side of the jar, but they colonized fine when spawned to bulk. I guess it really is hit or miss.

They didn't have wet grains stuck to the jar side. It was bacteria. A properly pasteurized bulk substrate has beneficial microbes that fight bacteria off. In fact if mycelium takes the upper hand like the jars in those pics, more often than not it won't be a problem. However it will ruin pinsets, slow down colonization rates, and EXTREMELY increase chances of other contaminations like trich or cobweb.
All those jars were used to make their own separate trays. The ones that were clean easily pumped out twice as much weight.
Dirty spawn:

Clean spawn:

That's good to know, I'll definitely pay more attention to my PC'ing times/inoculation procedures, I'd hate to prep all those grain jars and have them turn out to be bad spawn in the end.

yeah thats a great post mad!
there's a lot of threads where people use unhealthy spawn and claim success with poor sterile tech where you can see the BE is hurting from the cube myc having to fight another organism.
Imma take note and PM you next time I see it so you can post the pics!

What about shaking a 100% colonized jar and letting it re-colonize. Would that be any proof of clean / suspicious spawn? Like would a hidden trich node start to flourish if broken up and shaken around a jar? Might be worth waiting a few extra days if I can trick jars into showing themselves.

Yes. After shaking a fully colonized grain jar (highly suggest this practice everytime), it should fully recover in 3 days. If it takes any longer without a visual contamination, it's probably infected with bacteria. A majority of the time, mold will show up a day or two after the shake.

Mad season absolutely shows the difference and what i was dealing with. The almost clean jar is what had happened and the flush was weak which was a red flag, it still grew but it was just small
