i was able to get more crops by repacking the mycelium in new medium, in my case moistened newspaper packed tightly together and layered with moistened cardboard.
it worked well until i moved it to the garden hoping to have a regular supply. found out squirrels love mushrooms, especially oysters☹️
you're welcome. the mycelium will keep going as long as it has nourishment and will fruit mushrooms when it's ready.
just beware of squirrels 🐿️🐿️🐿️
