Your plan sounds good.. I’d mist that perlite down daily.. don’t worry about a little pooling

Thanks man. Everything seems fine. No growth, and when I moved the cake to harvest they were gone. Weird... I'm thinking it was a very bruised pin on the side. But now I have another question. As an experiment I had some horse poo and I mixed with with my CV. The water is now sloshing around the bottom of the shoebox and I'm not sure if it's a good idea that it's sitting in there. The substrate has already caked up and it seems to have all the moisture it needs and isn't soaking the poo water up anymore. Keep or dump 🤔 ahaha dump. Ok enough..

I would dump it. Sitting water is a breeding ground for bacteria.

I am dealing with a little cobweb mold in the corner of my tray, but this is something I haven't seen.  I had a relatively successful BRF trial and a moderately successful bulk with B+ (approx. 420 wet).  But what about this?  Looks terrible.  These are Burma and the primordia are thick.

It looks a little thick to be cobweb. Look at some other pictures of cobweb mold. I would say it's just bruised mycelium. I'm guessing it showed after misting? Although your sub looks a little dry to me. I like to see little beads of water on the surface of my tubs, until the little guys get a little bigger than what you have there, then I stop misting until after harvest. First flush on this one?

All I see is bruising, a little bit of metabolite stain, and a lot of pins.

Thanks guys!  I wasn't clear in my op.  The cobweb is in another corner.  I think I have that under control.  I now think the current photo is bruising.  It ironically shows better on the picture.  I also think my slab is too dry, which might have caused the bruising and staining.  My water/misting game has been off.

First time grower here. Could someone tell me what these dots are on two out of five of my jars? It's been really hot and humid here the last few days and I just noticed them today when I got up and was looking at them. They are PF Tek inoculated with spore syringes on 5/28. I know spore syringes aren't the best. I've been buying stuff to start doing Agar. Hopefully I uploaded these pics correctly.

Looks like bacterial infection and/or metabolites secreted due to bacterial infection. That amount is quite small. Wouldn't worry about it because there isn't anything you can do. Just continue on and fruit the cakes and see what you end up with.

Thank you. I'm just gonna do Bod's Easy AF cheapest way to get started TEK and throw some bags over them and fruit them that way. I appreciate you helping me out. Should I quarantine them in another room?

No, bacterial contamination, if that is what it is, isn't much to worry about. Just follow the dunk and roll and then fruit them. I wouldn't worry about isolating them.

Cobweb mold "under control" is as frequent as the common jackelope.

Are my shoeboxes contaminated, or to wet, or just normal?

It's just that I'm seeing some funny dark stuff at the top, and the mycelium in that area is not showing any signs of water droplets forming. Could that be an unwanted species sneaking in, or just really wet Golden Teacher mycelium?

Yeah I'm wondering if I should throw it out (if it's contamination), or try to dry it up a bit by introducing FAE (if it's just excess moisture).

Kinda looks like mold at it's first stages. But I'm no expert.

I would trash it. I hate saying that to people and I hate having to do that myself even more, but that's how things go in this line of work.

The yellow is just metabolites. It's not the end of the world but it means there's likely bacteria the mycelium is fighting. It may still fruit but your chances of getting more then one flush are slim. When the mycelium is fighting off bacteria it weakens itself and is more susceptible to molds and whatnot. I wouldn't trash that yet but don't get your hopes up to high. There is still a possibility of fruits for sure though. This shoebox of mine had metabolites but still fruited nicely and ended up with more then an oz off 1 quart of spawn.

Just pop the plastic off the side of the mycelium so the condensation can run down and so it has more surface area to breathe. You can still get fruits from that although it is less than perfect.

Hello everyone
It's been a while since I am trying to grow Psilocybe azurescens agar but what I get is like the image! I am very new to mushroom word :smile: So I am not sure if this is contamination or weeping! I use a lab autoclave and work under BSC. I would appreciate it if you let me know your opinions.

BTW IDK who to add the image here! I've attached a pfd file :smile:
