I've seen images of some jars that have a white fuzz over them, in which it's NOT mold but just "harmless metabolites." Is that, by chance, what I've got here (a whole cake-shot, followed by a close-up)?

Nope. Thats starting to look like a contam. The start of it is a very visible line, which makes me suspect. Google "hyphae" or "knotting" thats what you want to see, but its looking less and less like that. When you start over ditch your incubator and you will have better success IMO

Thanks for helping calibrate my eyes. They'll get it!

I keep seeing pics of people's cakes fruiting with the white fuzz (it appears that way, at least). To test whether mine is an issue with humidity, maybe I'll re-dunk, roll (which I skipped last week), put more vents in the dome, and see what happens.

I also keep seeing pics of fruiting cakes with blue on them. I'm wondering whether the ones I'm concerned about are fine. Still, I don't want to accidentally contaminate the one jar that looks good, solid, and white.

What you are thinking of is something we refer "fuzzy feet". Fuzzy feet happens around the base of mushrooms when they aren't receiving enough fresh air. Fuzzy feet isnt a contam and is totally safe to eat. It goes away when more fresh air is introduced. Here is an example:



To be clear though this only happens during fruiting, not during colonization.

As I said before there is a good chance that the spot on your jars is blue from bruising. If so it will go away once dunked.

And btw did you dunk and roll yet? your cake is looking dry so be sure to mist 3 or 4 times a day after dunking :thumbup:

It's great to hear about fuzzy feet; is there fuzzy head? ;-)

I'm redunking that dry cake now, and will roll tomorrow.

I'll definitely follow up. Thanks, man, for sharing what you know!

Oh, did I dunk and roll? Not the four other 1/2-pint cakes; they're only just about colonized. There is a very small patch of BRF not yet reached in each of two jars. Should I wait a week before birthing, to ensure thorough colonization?

I birthed the 1/2 pints, and their dunk will be finished later. They're looking good, and starting to pin.

I re-dunked and rolled the questionable cake. It's downstairs, but I'm getting concerned about cross-contamination.

Do these images confirm that the growth is white mold - and that this is not a cake to try to fruit?

I don't want to be too neurotic; but should I chuck this one, and disinfect?

I'm not seeing any pins here man. Or white mold.  Just knotting. Knotting appears before pins start to form.

Cut down your tinfoil squares into circles that just fit the cakes increase the humidity reaching your cakes and therefore yield. And, as I think I said before, toss that geolite thing and build a shotgun fruiting chamber to the proper specs.

That cake with the knotting is the one I had segregated because I thought that might be white mold. And knots are better than mold!

I have perlite on the way for a real SGFC. But I do still like the aesthetic of the dome on geolite in the tray:


There can be a lot of condensation, though:


Not that condensation means anything good or bad about RH, but my crappy hygrometer usually says it's 80%RH in there. But I should probably toss that device:


Geolite isn't ideal for humidity; but does this look okay for at least a couple days? I've got two airstones in an inch of water under the geolite - it's bubbling moisture up:


About the others: They're birthed...




... and rolled, and placed on foil circles:






I'm not sure how to spot early signs of dryness in the cakes. But their environment seems moist ...

You were right - I'll have shrooms soon!

PINS!!!! Alright buddy. Looking good. :thumbup:Things will speed up once you build your SGFC. 70% humidity is too low for cubes, your SGFC will give you the boost you need.

If your cakes are looking a little too dry you could mist them. When you say you "birthed" them you mean that you dunked them before rolling right?

Yes, I dunked about 18 - 20 hours in the fridge.

I'm not going to be able to make the SGFC tomorrow. Should I use a different dome for better humidity? I have one with open/close swivel valve holes; so I can tweak my way to decent humidity/FAE levels, and fan periodically.

Itl be fine for a day or two. Just so you know "cold shocking" is bogus. Cubes dont need to be dunked in the fridge, they are a tropical species.

Let us know what happens man :thumbup: Keep the pics coming

The growth is on!

Quick question: Is the "white fuzz" hyphal knotting? And definitely not a white mold?



Thanks!

Well, damn! I isolated the other cake thinking its fuzz might be mold. It looks like it's been hyphal knotting all along. And that isolated cake is showing its first pin today.

Perhaps I should move it in with the others; their chamber is better.

Thanks, thanks for all the diagnostic assists!
