Can you tell me if any of these cacti are san pedro?? It seems like you have to know your shit about cactus to tell if its a san pedro or not. Any ways of identifying a San Pedro??
Do some research and find out what the characteristics of san pedro are. What they look like, what their flowers look like, where they grow what they taste like after a while it will be like telling a male from a female apart or a mountain from a whale just learn you'll get it . .
The subject of trihocereus identification ir wrught with havoc many hybrids, but those for sure are NOT. There is a book entitled 'san pedro and other related trichocereus' thats very good. By KT Trout
