i don't know a great deal about growing shrooms yet as I've still yet to start with my roomie. But anyways, if you make sure it's psilocybin cubensis and not cyanesens or azurean (i don't know how to spell it, but it sounds like that) then whatever strain you order should be able to grow you some mushrooms relatively easily if you go through all the steps properly. Strains can vary greatly, but generally the growing techniques for all cubensis are the same from what I've researched.
Your best bet would probably be to ask the folks at shroomery. I'm thinking I'll grow some over the summer aswell, since until recently they've been quite hard to find here.
