dose it have to be vermiculite and if a shroom was infested wiht a bacteria or mold or fugus would it kill you? i heard a story that someone at a shroom that was not sterilized when growing and had a bacteria on it that killed the person think a bacteria or mold would do that?I've heard of people microwaving their medium to sterilize it.
Spores are illegal in georgia, california, and Idaho. Most places will still ship them though. I order from: http://www.ralphstersspores.com/
If you are using the pf tek you need to use vermiculite.
And a pressure cooker is a real good thing to have, you need it if doing grains. I've heard you can get by sterilizing the pf tek jars in boiling water but I'm not sure how long.
