Pinning outside of the jar is the more standard approach really. Stamets for instance never references pinning in the jar, etc. I think it all came from PF. (Although there are the bag techniques where you cut wholes in the bags, and the mushrooms come out of there)

And to answer the original question. If it doesn't pin in-vitro, simply birth it, put it in the terrarium and it will pin. Or case it. Removing it from the jar lowers the temperature enough to trigger pinning. A poor man's "cold shocking".
