My Mescaline expectations

Man I gotta try growing some of these too. I'm sure I won't be finding any mescaline around me other wise. When I went out to arizona this spring to visit family I was looking at all the cacti as I walked around trying to look for San pedro esc features. But being there visiting my parents I couldn't really mess with any even if I found one. There were a few that I seriously thought matched the desciptions/pictures I was finding on some cactus guides online.

id read up on feeding them,i dont know alot about succulents,but i do know you should use half strength,and feeding too early can stress their tiny little roots..
