Sorry, I may have been too vague. I grew them in a large plastic bin in my bathtub. I got the spores and was able to start the mycelium without any bacteria problems, somehow (My kitchen was no more sanitary than you would expect from a 21 year old bachelor). I really had no idea what I was doing so, based on the stories I hear of other people trying and failing several times before giving up, I assume I was just exceptionally lucky. :)
Edit: Ah, I get your point about selection bias now. Yes, based on self-reporting on drug forums I am surely in a small minority of clueless yet successful psychedelic mushroom farmers. I suppose if I ran through a minefield once and didn't lose any limbs, I would think that was easy too: "just run in a straight line as fast as you can, no problem!"
I also had success growing mushrooms at around that age.
I just followed the instructions and did try to take extra care with cleanliness, my guess is that as we're both here on HN we're probably predisposed to be better at following a process.
