Question:

Changing the mushrooms?

I have made a few PF Cakes out of vermiculite, brown rye flour, in a few glass jars and a syringe of mushroom spores.(in Aug.) I followed all of the steps, gave birth and grew a few batches of mushrooms, but I don‘t like them. Can I buy a different strain of mushroom spores and plant them and grow them on the cakes I have already birthed and cultivated a few times? Instead of having to make a PF cake from the beginning with the brown rye flour.

Answer:

Sure, you can just use different spores on the same medium.
That will work, unless the previous mushrooms have matured and deposited some spores in the medium. That would mix the varieties and you wouldn't have a clean start. New cakes would work the best since the nutrients are not depleted.
