Deriving from my last post about Stroma, there is a question that's been bugging me for a while: What is the ideal CO2 levels for a Spawn incubation room? And the questions behind it: what is the correlation/ differential between the CO2 concentration inside the bag compared to the room (has anyone tested this)? What are the thermodynamics going on between temperature and filter patch gas exchange.

And going off of that, how does humidity/temp/ FAE affect the moisture inside the bag. I often see the grain on the surface of my spawn drying (I'm assuming) because it doesn't get colonized.

If anyone has any resources to point me to, I'd graetly appreciate it.

It's time yall write a detailed book. Strain list with pictures and best practices to grow it. Key information only. What type of bag is best, media ratios, colonization time with picture of ready to fruit bags, time expectations, etc. A simple detailed one page on each mushroom to get the best results. Then sell it for $ hundreds. I love listening to the podcasts but I'm typically working when I do. This leads me to not catching the 2 or 3 important things that are said on a 2 hour podcast.  Going back through the videos can be a nightmare to find that info again. As there is A LOT of filler talk. Which I love, but when im in data harvesting mode can be hard to collect the pertinent info. Yall make me laugh and I really do like listening to you once per video only though. Give it to me straight sell me your knowledge in a straight forward CLEAR no filler format with colored pictures. Maybe even some pictures we can color in back of the book jk or am i.

First of all mad props to the MycoWizards team!! 🤯  Y'all are crushing it and I'm so grateful to be a part of it.  I feel like you made the King Trumpet Video just for me and I haven't had a chance to watch it or much of the new stuff but tomorrow is the day!!  It's my day off and on full on Dad duty but I'll be streaming your content, working on my "Youtube University Mushroom pHD".

Enough smoke blowing... So, the main reason I reach out to everyone is, there's an auction locally that has this and there's no info about it.  The picture sucks, I know!!!

I can go look at the item in person on Thursday but does anyone know what this is (name, make, model)?  The size of the vessel?  What it runs on?  I guess just anything about it and if I should get it if it's a couple hundred... or couple grand or twenty five dollars?  IDK JK

STROMA? 

[Update: CO2 levels also increase from about 500 to 1300. Maybe that was a contributor? 

Is this stroma? Refer to the videos in this link please:

This is the first time this happened. I obviously let this spawn incubate for too long, as you can see from the mycelium growing up the walls of the bag, and the temperature went from constant 70F to 78 for at least probably a couple days towards the end. I only noticed this growth in 3 of 15 bags. What are the chances the others have it, but it is hidden? You're feedback will determine whether I will toss the rest of the lot or not. Thank you!

New wild Hericium trialing out from 2023 clone collection.

Can we talk about the pungent odor of substrate when growing COW for a bit? I have heard others mention it but wow its rank, I was convinced it was bacterial but plates are all clean and I can't find it. Anyone else experienced it?

Hey y'all hope you enjoy our first of many sterile technique videos!! There was a minor yet important detail that wasn't mentioned. So whenever working in front of a HEPA filter be sure to never spray the isopropyl directly at the filter (due to damage). Always keep the spray bottle very slanted or even perpendicular to the filter. Also spraying with a downward angle and close to the object helps prevent the large spread of harmful isopropyl spray. Lastly, with an open culture these rules have to be followed to ensure no damage by isopropyl occurs to our live open cultures. Sorry about that and let me know if any other questions arise!

I grew cordyceps on Jeff's egg sub for the first time year ago, dove down the rabbit hole pretty fast since. Really interested in what you guys are able to share on cordyceps strain maintenance/breeding/cultivation. I have gleamed what I can but right now cordyceps growers seems to be looking down on sharing more than ever. A lot of "figure it out for yourself" especially with seemingly simple things like...

-What is the general lifespan of a new strain? Like on the plate, then in the master LC and then subsequent production LC. 

-What are the storage options like? I assume cryo is a no go but no one will say. I like hyphae suspended in sterile distilled water for gourmet and am trying that for cordy now, will test 6mo/1yr for viability. 

Where I spend my summer here in the dense Appalachian forests I can find hundreds of wild militaris easily and started collecting them last season for cloning/breeding. Most went to waste but I want to try again this season better equipped (with knowledge more than anything. Appreciate anything you guys can share!

Love the simplicity of eggs and rice, gives me a tax write off for the free range ducks and is a selling point for the cordy I grow*

Thank you so much Eric for that latest episode on Stroma – seriously, it confirmed some suspicions I've been nursing. Specifically, I noticed this whole issue mostly kicking off with a certain strain of blue oyster, especially when the spawn got a bit too carried away. Once that stuff grew into these big, melted chunks, boom, Stroma was practically guaranteed. Thanks, Eric, for breaking it down!

Hi there! Regarding your coroplast HRV deep dive: Do you think a 2'x4' coroplast HRV unit, 40 layers thick be sufficient for regulating a 8'x10' size grow room?
