Mushroom advice please

[QuizMaster]

Hi.
I bought a packet of dried spores (or whatever they are).
I'm wondering what to grow them in. They will need to be indoors, as it gets too cold outdoors at night in these parts, even in summer. Besides, anything we put in the shed is just by way of feeding the mice.

But if I have them indoors, I will need something that doesn't stink. Well rotted manure they say. We have well rotted kitchen compost but it's not the most fragrant. I have a huge pile of grass cuttings that's a bit rancid if you dig down far enough. That's probably good for them too but again with the odour.

Any suggestions? Or any mushroom growing stories good or bad?

Interesting fact: When I was a lad they were plants. But now they have been re-classified into a "kingdom" of their own. Not plants, not animals, but fungi.
