Let us first begin by identifying the varieties (var) that we are going to be discussing. There are 3 var in particular of the San Pedro Cactus that we will be discussing. Trichocereus Pacahanoi, Peruvian, Bridgesii. So far these are the ones reported to have entheogenic psychoactivity and the ones in which we will be discussing. The techniques described apply to all 3 var. T. Macrogronus has yet to become a common ally among the 3 var. as of now. Further reseach, study, cultivation and extraction will yield the needed data for the future. San Pedro is interpreted into St. Peter who is keeper of the gates of heaven. So the cacti is the key to enter into through the gates or veil to the eternal awareness of the never ending moment. Step 1. Growing a Cutting. This is by far the easiest step. The thing about the cutting is that it can remain alive for a long time as a cutting out of soil. I have not tested a cutting to suffer a long death for the data, but I do know it will start growing pups even out of soil. The best place to start is an online vendor otherwise you will have to harvest a cutting from a neighboring yard. The average price for a cutting is about $25 per foot. I know the pachanoi var grows in many neighborhoods of the southern california region. I seldomnly come across pervian or bridgesii, but I have. And when the day comes that I can grow the sacred cacti in my own yard I will. For now I wait and allow them to grow free. On a journey through phoenix Az. I did happen to spot more peruvian var then the other two. A 1ft cutting is standard to start growing and using sacred cacti. Simply plant the cutting directly into common potting soil or cactus potting soil and start watering. You should start with a 3-5g plastic pot. Plastic pots work the best due to the fact that they retain moisture longer then clay. I've noticed that the San Pedro var. cacti grow best in indirect sun with plenty of watering, but they can handle full sun as long as they get plenty of water. Lack of water seems to make them prune up and in full sun they become yellow. The most potent samples you are going to want to use for brewing/extracting are going to be the darkest green and very juicy. Every cutting that was less then a foot that I had planted always grew pups on the top and the cutting only remained a base. Once any cutting has established roots it will begin to grow pups out the base. For cuttings that are not tops there is a way of cloning from these that I have observed. What you want to do is cut the cutting into 2-3in long chunks and plant them half deep on their sides in 1g plastic pots. The pups always grow out the side that would have been the top end of the cutting. For example if you layed a 5ft cutting on the ground and let it sprout a pup. It would grow out the part of the cutting that was its most top part and the remaining 5ft of cacti will not sprout any pups. Whereas if you cut 5ft into 30x2in chunks you could sprout 30 pups. The rule is confirmed that the cacti grow about 1ft+ a year once the roots are established and have plenty of room and watering.
