In your original post I could not avoid noticing that you started your
culture after cooking the mushrooms somehow.

No no! I did not cook the mushrooms I used for planting! :-)

I cut off the stems and bases, and cooked the caps and ate them! I used
the raw stems and bases for the original puree... They are not as tender
as the caps, and they were the basis for my spawn.


Thanks. I have some experience with commercially available spawn, but
none with homegrown. I suppose this will work with all the fungi which
can do without much N, and that of course includes oyster. But even
they enjoy the addition of boiled coffee grounds (which also provide K
and acidity). If you are willing to sacrifice one of the rolls, you
could try to break it and spawn a few gallons of a coffee
ground/grains/straw/woodchips mixture (choose any of the first two,
any of the last two, duly boiled ahead, easy to do if you have
beermaking equipment), and then you would be able to harvest a few
pounds of oyster. But I think I will try your blended stems trick,
make a pile outside (coffee makes both oyster and green molds go very
fast, but the mold usually wins indoors, loses outdoors), see what
happens.

Did you bleach and rinse the stems to sterilize the surface before
blending? I wonder if UV would work also, since I have access to a UV
machine.
