Bought a medium size bag to see how it goes. The guy selling them says it's still a bit cold to grow them outside down south - frost is the main issue and they grow very slowly in the cold.

So we'll try this bag inside and see how it goes. I'm going to have a go at growing spores after we've done a third harvest off this bag. If I can get some going I'll inoculate some wood shavings. Otherwise I can buy some spores off this guy and try that.

It sounds very much like a trial and error thing until you get just the right conditions and ensure you are fastidious with cleanliness when growing spores.

I really want to try this again, but, I know it's probably just cheaper to buy mushrooms.
