mycotopia is definitely a really great site, but that hippie character is really uptight. other than that, lots of really great info, especially if you get into advanced cultivation. lots of really smart people post there.Shroomery is sub-par IMO. Go check out mycotopia.net, much better site http://forums.mycotopia.net/new-vaults/ has all the info you need for every type of growing
You can also check out www.mycrotopia.com which is sells pre-sterilized PFTek jars as well as bulk substrates and other goodies.
