As far as growing the sclerotia and not trying to fruit ATL#7 goes and bearing in mind you have a pressure cooker.....well growing the truffles is easier then cubes. They take longer but they are easy to grow.
If people would be interested is seeing me grow some on here ill start a magic truffle grow on here as soon as we move. Im going to start 15 jars as soon as we are setteled in. As well as some liquid culture and agar experiments.
