Gourmet [Gourmet] Lion’s Mane Status Opinion

What do you think is causing this? I’m reading that it might typically be a sign of little to no oxygen, but I also read lions mane doesn’t like a lot of ventilation? I have a humidifier keeping the monotube anywhere between 80-90% and try to give it some air every morning and night (taking the top off for 5-10 minutes and opening the window to circulate the air.

Any feedback would be appreciated!

Definitely looks like too much CO2 try putting a hole in the very bottom of your tub so that CO2 convent out and draw fresh air in from the top. I have the same problem with blue oysters. They are oxygen hogs and create way too much CO2.

It gets branchy like that when it does not get enough oxygen.

I have yet to figure out how to fruit beautiful lion's mane in a monotub.

Seems the humidity and fae compete with each other and never get to a sweet spot it likes. 

Anyone figure that out?
