In my experience, using these two sites is the cheapest way to get a grow kit (I innoculated 10 bags for $150. My last kit I got was $130 for one from http://www.homesteadbook.com).
sounds like fun,,,I think doing a shroom grow would be a good change....even though I stopped doing them,, Maybe I know someone who will take them so I can watch.......
special? not sure what you mean. For CA/US ..... ralphster's has been VERY reliable and great quality. The Shroomery is a site similar to RIU. Good luck!!
