Three days ago I added grain spawn to pasteurized dung/straw. It has become very stinky. Sulfur like smell. The sub was heated for 2 hrs @ 160 Is it normal for bulk subs to stink before the spawn run is complete?
Don't sound good.
Pastuerizing sub is not a option unless it's for PF.
The dung/straw should have been sterilized in a pillow case in a PC.
You shouldn't smell sulfur that's for sure.

I have never smelled anything like what your describing. What did you let the spawn colonize the sub in?, what temps did you let it colonize? and how long since colonization?
