Inject either spores or liquid culture into either hydrated rye grain or popcorn. Shake accordingly, and then mix with a substrate. And then case. And then fruit BIG. Really, I did a LONG description above. And then realize those FUCKING compact jars of slow growing myc in those PF jars are STILL not done.What alternative would you suggest?
That list of things above sounds like a difficult process as compared to PF, but really, I've been there, and it's WELL worth it.
