OK I’ll play around and see what I can make work. Considering I seem to be having good success with the cremini spawn (which was literally just bringing the cardboard and water to a boil and then laying out on the countertop to cool down for about 30 minutes) I’m hopeful that I can pull this off too. I live near Denver Colorado so we’re quite high with a pretty dry climate usually, but we’ve been getting a LOT of rain this Spring so I figure the risk of mold spore is a lot higher that normal.
Anyway thanks for all the advice! Hopefully will be posting pics of some nice grain spawn in a few weeks!
