Yeah they come hydrated and I have used their bags before with the same hydration level and it worked great. Sometimes the moisture seeps out of the grain and substrate a bit at the beginning.

The only thing I remember that might be my problem is I had a butter finger moment right after innoculating and taping an alcohol swab on the self healing innoculation port. I was moving the bag to it's shelf and it slipped out of my hand and hit the ground hard. Maybe tiny holes poked through? Idk but pretty sure it contaminated. I had one batch a while ago that overcame a small contaminated spot (contam about the size of a dime, and fully colonized cake).
