Green mold ? Yea or Nay?
    #19283750 - 12/16/13 12:47 PM (10 years, 1 month ago)

Hello all! Thanks for the visit! Anyways, I was harvesting my BRF cake Ecudorians that are grown in a FC with perlite, when I noticed something odd in the corner of one of my cakes. I took a closer look and fear what every mycologist does... MOLD! Due to my inexperience in identifying mold over the natural blue bruising, I feel that it would best be left up to you. FYI I have already separated the cakes in question! ALso on one of my cakes there is only one fruiting body and it is very odd and different than any other mushroom I've seen, anyone got a clue what it is/what I should do with it? Thanks for any help!

First 4 pictures are of mold in question, last two are of the mushroom.

Weird mushrooms are common, why not use that search bar in top-right corner and so some research on your own?

And about cake, most looks like bruising, except in your 1st picture left from mushrooms growing it looks a bit like green covered pin? If it did its not good. Blue is good and green is bad.

I don't see any mold but the green spots are too out of focus to see. If it's mold it'll have a powdery texture.

Unfortunately it did turn out to be mold, I removed the cake from my FC when I first suspected that it was mold and put it into a separate tupperware container. After letting it sit there for a few days it started to really get green and there was a fair amount of a spongy stringy type of mold on the top of the cake pictured. I had hoped that it would have ended there... Unfortunately it seems that my entire FC had been compromised at that point because my other 3 cakes in there all grew mold within the next few days.

My question at this point was how could this have happened, and I know with mushrooms it all comes down to sterile technique. I tried to narrow down the sources of contamination and one thing that I thought of was that the water that I used to spray the cakes was right from the tap. Has anyone ever heard of anything like this happening? Or does anyone have any tips in general for good sterile technique?

Mold doesn't spread that quickly. So if you had it on multiple cakes in the same flush it's because the cakes were contaminated around the same time. It most likely happened before the substrate had fully colonized. So either mold spores got in the jar while they were colonizing or you birthed them before they were completely colonized.

Spores can get in a jar if the dry vermiculite layer was jostled around or becames damp. Also can be from contaminated spores or using a contaminated needle during the inoculation.

I had harvested two of the cakes before any signs of mold so I don't think that they were contaminated during inoculation although it could have just grown really slowly. I actually stumbled onto the mold while i was harvesting one of the other cakes, it was about 5-6 days from the time that I isolated the cakes in question to the time it spread to the other cakes. Another thing worth noting is that about a few days the mold started to grow i birthed a new cake into the FC and was misting as i said with just straight tap water. The cake that i misted wasn't the first one to get contaminated, but it was the most severe in the end when all of them got contamed.
Since all of this contamination I've really been considering switching to rye grain instead of BRF, I bought RR's video so I have all the basic instructions for it. Any tips for trying to find a cheap way to make a HEPA filter to open the FC near to prevent airborne contamination? Because I still feel that the two main sources of contamination were in the water i sprayed and the air that was around the FC at the time of fanning. Thanks for all the help thus far!!!

You can gently put a damp paper towel over the contaminated cake and wrap it in that to prevent the spores from spreading as you take it out.

The water wouldn't be the source but misting can certainly promote mold growth on a cake that is already contaminated.
