@kcult I don't have much to add to what Bill posted above. There is more information than you can absorb on the YouTube.
I bought plugs for Italian Oysters, Pohu Oysters, Lions Mane, Shiitake, and sawdust medium for Wine Caps from
Field & Forest Mushrooms. I inoculated the fresh-cut logs with the plugs as Bill described above, in March of 2022. I did use the wax. The only thing that fruited that year was the Pohus, two fruitings. I have mycelium on all the logs.
I built a cardboard & straw bed for the wine caps, inoculated it and covered with shredded hardwood mulch from a local farm supply. Everything looked great until about July, maybe August. I went to water and the whole bed had brown rust mold in it. I looked at the hardwood mulch pile I had bought and it was full of brown rust mold too. So yeah, those bastards killed my mushrooms.
Be careful what you use for growth medium I guess, try to get everything from a known source like your hunting property or somewhere if possible. I just bought a decent 4" chipper/shredder yesterday so I can start making my own hardwood chips for bed-type shrooms & chicken-coop (run) composting.
Also, even though all my logs were fresh-cut, some of the oak has a funky oyster-type shroom on it already that is really woody in texture and can't be any good to eat. It may not be toxic but it would be like eating tree bark. I'm not sure how badly that will hurt the other plug spawn when they start to fruit. This is mainly on the Lion's Mane logs I think.
