Hi I just finished a round of blue Oysters. The mushrooms turned out pretty nice but at the bases there seems to be a bunch of aborting pins. What causes this? See attached pictures. The picture with the glove is an example of the aborting  pin. Thanks

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!

Hey Y'all. Happy new year!
I thought I might share this article of a sweet initiative that is growing from the decomposition and repurposing (and reappropriation) a large agaricus farm, including training the majority immigrant workers from the old farm, to form a cooperative exotics farm owned by seven Mexican and Guatemalan immigrant families. It's cool to see the previous workers taking ownership of the "means of production" with the hope of creating a better working environment and offer opportunities for others to grow and benefit together, rather than be exploited migrant labor. A hopeful story to inspire us with alternatives and possibilities to start the year.  A farm to keep on our radar to support in any way.

Lion’s Mane

My lions mane was growing nicely. Picture 1. 

Some of the blocks started to have some slightly yellow softer spots. Pictures 2-3. 

What  causes this and how do I avoid in the future?

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?

I'm about to watch the coroplast HRV podcast for the 5th time cause I'm trying to cook up a way to integrate them into my warehouse build. I mostly understand it, however I get a little confused with how the air is being pulled in from the bottom as well as being exhausted out the bottom. Is that bottom 'spore dump' zone walled off below the vent to keep the air systems separate?

This is probably my best so far. Tried many variables/recipes and I really like basically Ryan Paul Gates's broth with 1 egg. 

Cordyceps 

I'm having some fruiting issues. My oyster sawdust bags are full colonized, the grow-room is at 60 F, humidity at 85%, CO2 is at 600ppm and, I have Lions Mane in the same room that is doing fine. Any thoughts or suggestions?

 Beech Mushroom

Hey guys! Just got a bag of capnstems beech mushroom spawn. I’ve never grown beech before.. I have a chef that is wanting to get some from us. I’m curious if anyone here grows it? I would like to know incubation time, and fruiting times on these guys!
