i just got two very small cactus from home depo, they look alot like san pedro and i know that san pedro is widely carryed so home depo would have it, it wasnt labled, so is there any way i can tell for sure that it is san pedro. there a littile crappy but if anyone can tell that would help thanks
Well they look like San Pedro to me. Except that I don't recall them tapering at the base like that...but maybe the babies do...wait it out. San Pedros grow rather quickly.
I would say that you have San Perdro/ Trichocereus pachanoi there. Let those grow and you'll be in for a real sacred treat. Those are mere pups still. They however grow very quickly and I would say in about 7 to 9 months they should be sufficient for usage. Enjoy. I know I have for many years.
