Green Racine – Lots to Plots

With the return of the Blue Green mold of Death I need to find something that will work to fight it in the Coffee grounds.
I know that cooking the grounds longer to insure all nasty are gone, maybe 3 hours vs two.
Thinking somehow perhaps the plastic grow boxes harbor the mold after being washed with Bleach.
Perhaps I need to try to grow the shrooms in glass jars? Worth a try.
Like to use something other then the small caning jars I have. Guess an on line search is in order and visiting some estate sales
I wonder how the early growers did this back in the 1800′s time to dig out the old book I found in Goggle books
