Please note: I am not responsible for anything that may go wrong after purchasing this spawn. The spawn has been used by me and works well. However it is the buyers responsibility to educate themselves on cultivation of edible mushrooms.

I can supply some basic instructions for growing on straw if you need but they are not to be relied upon.

Feel free to ask any questions.
