It mentions using straw as a growing medium.

Yeah, I've read those instructions. :-)

Going to have a go though, nothing to lose.

*nod* The key thing is to make sure you put it somewhere slightly cool

don't let it dry out. Very difficult in a centrally heated house,
unfortunately. Cellar would be ideal!
