i didnt know what i was doing at all when i started my shroom grow..but i just tripped for the second time yesterday off my shrooms.
if you can follow instructions, step by steps, without fucking it up..you can grow mushrooms.
Ive got B+ strain, but as gogrow said ive heard alot of things suggesting that most cubensis are very similar.
Watch tons of youtube vids about growing shrooms, read as much as you can comprehend at shroomery, search through this forum...find a guide that you can follow, and do it.
my journal is packed full of questions ive asked and problems ive come across..some very smart and helpful people are reason for my success
anyway, good luck.
