Hey man thanks not sure exactly what kind it is as its one of the few ive ever been lucky enough to see. Grafting is definately the way tho if you wanna watch em grow as fast as a san pedro. This graft is about 3 years old now and the peyote was much smaller when i first bout it. Im sure the peyote was roughly 4-5 years old to be that big when being grafted onto a stock. I got it as a graft though.

and in about a year it grew 7 pups and this is the first flower although ive noticed it almost pop out before
Heres a good video on grafting hopefully this helps you out

the other vid is on his youtube profile btw
