So no contamination, just aborts?

Yeah, though it can get into a gray area, i.e., if you leave the aborts to rot then they can be a place where contaminants get a foothold, if you have bacterial issues then you may see more aborts that rot faster, etc.

Either way there ain't much to do but clean them off and see what happens...

Beware of advice- even this.

Hi all. Can someone help me about this one. I had 3 monotubs. When i activated FAE, trying to put them in fruiting conditions, myc in all 3 tubs started to darken. It looked like some kind of bacteria or bruising to me. Darkening progressed rapidly in few days, so i was thinking myc is rottening or something. After few days two tubs were attacked with trichoderma. For a long time i was thinking this is bacterial but now im not sure is it maybe exttreme bruising, cus my last tub is now pining and fruiting.

This is grain spawn in horse manure and verm. Myc was preaty fluffy as you can see. There was some so called myc piss on spawn.

That alone says your spawn was highly bacterial and maybe worse. I wouldn't hold out much hope for that tray as when your spawn has metabolites ( not myc piss as mycelium doesn't pee ) before you spawn to bulk its gonna be way weaker already. I would get a new project going and toss that tub. You could maybe harvest whatever that is but I personally wouldn't mess with it.

So, I've been struggling with this Tidal Wave clone culture for a while.. I think it's enmeshed with something that I can't seem to get rid of.. it gets to right around the first flush pins and trichs out on me... I've taken plate pins to new plates and had the plate pin go south on me..

This jar looks exactly like the last 2 that contaminated right before the first flush.. does it have some visual signs that are indicators of the spawn being the issue?

I'm thinking about trying to top fruit this one to see if I can actually get something..
(I know, it's probably time to trash the culture and move on)



I'm taking one last stab at it after this jar with a plate pin I cut open and took a tissue sample of to see if that will come out clean..




How are you prepping the millet? I transitioned from rye to millet and started having lots of contam. Switching back to oats for the meanwhile in hopes to avoid this.

Hi, still fairly new to mycology, so hopefully I didnt mess up too bad

I found some deep red streaks on the grain in my spawn jar. Not sure if its a contaminant or what (it probably is), besides that it seems like all is well
I'm more curious as to what that red "stuff" is to prevent it from happening
Hopefully its not too bad

What contamination is this? Myc was white, was told it was dehydrated, started misting more, pinning started quickly, then color changed. Is it penicillium?

I couldn't zoom in, so I'm not positive.. but it could be bruising from letting it dry out and then misting it... if that's the case, it will go away after a while... it definitely looks dry from what I can see.. hopefully someone else that's using a device with a bigger screen will chime in and confirm or correct my theory

The blue color I was told was bruising, I’m referring to the yellowish green color.

The yellow color is from the mycelium drying out. The blue is bruising. Mix yellow and blue makes green. I don't see trich so I think you just beat your myc up a bit. It should recover.

Oh, I believe that's from it being dried out, but wait for a 2nd option just to be sure

Thanks for the info. Should I be doing more than misting? The surface has tiny little water droplets all over it, I mist several times a day. Should I pour some water down the side of the bin so water can get underneath?

You can try side watering but only if your sub is dry not just the surface. It's up to you, if you think your sub is dry go for it. I put about a pint down the side and wait 6 hours. If it's gone I add another pint. After another 6 hours pour off the rest by holding your sub gently and tipping to a corner. Usually it won't take that much. I go heavy on field capacity now so I don't need to side water till about the 3rd flush or so. Too much misting will cause matted mycelium. You don't want that. You really need to dial in your FAE. it should be high enough that water beads evaporate after a day or two. Honestly if your field capacity and FAE is perfect you shouldn't need to mist before the first flush, or at most a few times. It sounds like you have a high fae if you are misting that often and your surface is dry by the time you mist again.

Red is usually a bad sign, but I’d wait for someone more knowledgeable than me to chime in.
