Recently revisiting the site of a shady grower has demonstrated that false informatiom is being propagated online about Trichocereus allies with mescaline content.
The purpose of this ongoing thread is to address myths and lies that are easily found online so that those interested in these plants can have decent information.
The first myth to address is that there is only one true San Pedro cactus. The term San Pedro, meaning Saint Peter, pertains to a spiritual practice in which Saint Peter represents a spirit invoked and involved in Andean Shamanism. This term is widely applied to many cacti in the Andes, including T. peruvianus, T. pachanoi and T. bridgesii among others, it is not specific to T. pachanoi at all, that is a myth. There are many cacti known as San Pedro, further more there is a related myth stating there is only one form of T. pachanoi, not only is this not true but there is an abundant amount of evidence illustrating this well, including photographic evidence from the Andes and numerous collections of plants and seeds from the Andes.
Related to this topic is the clone known as the PC clone, also called by some other names (including the Cactus Kate clone), this clone is the most abundant trichocereus in propagation today, but is atypical for Andean pachanoi and is quite weak despite being a fast grower. Pachanoi from the Andes are not like this clone at all, and many experts believe that the PC clone may be a hybrid. It is my belief that this is the case and that the plant may be half cuzcoensis given the traits of the offspring of the plant, it appears that the plant contains alleles for long spines that are recessive to a short spine allele, likewise despite being alkaloid rich and very bitter the plant contains very little mescaline, from none at all to typically less than 0.1%, making it 10-20X weaker than some authentic T. Pachanoi!
The second myth to address here is that T. peruvianus contains more mescaline that T. pachanoi. Not only is this not supported by analysis, the opposite is indicated. Levels of mescaline in T. pachanoi have been measured as high as 2% whole plant and >4% for the outer skin (both % are for dry weight) while T. peruvianus has measured near 1% whole plant in a case of a plant that appears to have been misidentified T. pachanoi, KK242, which as a number indicates an area in Peru and not a plant is used for a number of plants collected in this range including T pachanoi, T peruvianus and T. cuzcoensis. In one recent analysis of dried outer skin T peruvianus was demonstrated to contain 0.24% mescaline, while in the same study the strongest T pachanoi was 4.7%!
If we include the variety T peruvianus puquiensis a recent study found the values:
0.11%
0.13%
0.28%
0.5%
this was all for dried outer skin!
It is worth noting that several studies of both T pachanoi and T peruvianus demonstrate a range of mescaline content and in some specimens found none at all. However even with the range the indication of the data is that T pachanoi tends to be consistently stronger than T peruvianus.
The third myth ] is that the majority of the alkaloid in the plant is in the outer skin, while it is true that the outer skin contains the highest per weight concentration of mescaline or alkaloid found in the plant it is also true that the outer skin is a small fraction of the plants overall weight, while the inner tissue is much greater in mass. So while the inner tissue is weaker on a weight for weight basis there is more of it and as much as 2/3 of a plants alkaloids can be in this inner tissue, despite the strongest concentration being in the outer tissue.
The fourth myth is that analytical data is conclusive enough to extrapolate into expectations of yield. Even for a single clone of a single specimen there is evidence that variation occurs both seasonally as well as in other ways. You might have a clone that has been demonstrated to have mescaline and you grow and extract it and get nothing at all or get a weak yield, and then you try it another time of year or at some later point and get a decent yield. Anecdote indicates that mescaline recoveries tend to be highest when cuttings and plants are in a dormant state, often giving the best returns or effects during the winter period. This does not mean plants are not active or incapable of being potent during summer, just that in the experience of many people plants tend to be more potent in winter.
In one very interesting analysis by Shulgin a T pachanoi specimen which has been named Juuls Giant was demonstrated to have little mescaline (<10% of total alkaloid) and instead had an unidentified isoquinoline as the predominant chemical, another analysis demonstrated an unknown alkaloid with no apparent mescaline and yet another analysis demonstrated 1.4% mescaline in the outer tissue!
Interestingly some cases are also known where a plant when ingested or made into a tea or brew was considered fairly potent but upon extraction did not yield much mescaline at all. Many questions remain as to why this is and various theories have been proposed.
Myth five is that these plants are best cared for like cacti in general, while it is true they are cacti and they also vary to some degree regarding their care they also come from a climate that often receives 3+ feet of rain a year and most of this during the winter cold season! These plants often not only tolerate but prefer heavy feeding and watering and thrive in a rich environment. I have seen the PC clone growing in containers which did not drain where the roots were submerged in water for months at a time, this would kill most cacti and will kill many Trichocereus, however it demonstrates how hardy these plants can be. Ideal care for them includes a lot more water and food than most people tend to expect. under ideal conditions they can grow around 3+ feet (a meter)a year! The conditions they prefer are a lot more like those ideal for corn or some other leafy plant and not much like is typical for many cacti. Some forms, clones and specimens are a bit more sensitive than others to wet conditions, however many growers do not let the soil grow entirely dry or tend to water as soon as the soil dries, during the active growing season. Many growers who bring their plants inside do not water them during the winter, however if your climate allows them to be grown outside year round they enjoy wet roots during winter or the cold season. They typically tolerate cold to around 20*F +/- 5*F.
Myth six is that the best way to grow a large amount of cactus in the shortest amount of time is from cuttings. A cutting tends to double in size yearly until it is established and then branches that are actively growing can grow up to 3 feet a year or so. Seed can be a bit slow to establish but can in many cases yield established plants in 3-4 years. However seed is not particularly expensive and so you can grow hundred or thousands of seedlings in a few years, to grow the same amount of cactus via cuttings would be ridiculously expensive. Moreover when growing from seed there tends to be variation allowing selection for desirable characteristics including potency, growth rates, tolerance to water, sun and fertilizer and other aspects. If the parents of the seed are proven plants the seed tends to produce proven plants and these days high quality seed of proven clones is easily obtained through purchase or trade. Even when dealing with seed of unknown heritage of varieties like T. bridgesii and T. pachanoi you are liekly to obtain many quality specimens. I prefer hybrid seed for specific reasons including vigor, however seed of hybrids and pure forms is widely available if one knows where to look and is often inexpensive, prices of $4 per 50 seeds or lower are common, though some more expensive seed can be found.
It is also a related myth that seed of cacti is particularly hard to grow or requires special conditions, this is not true. I have thrown seed on top of dirt and watered and had seedlings grow and just watered them when the soil started to dry out and had them grow very well. Issues such as rotting or fungal problems are rare when using a healthy soil and are typically only an issue when people grow in enclosed container that do not breathe, are too wet and involve sterile or axenic conditions. The truth is that cactus seed is ridiculously easy to grow. Likewise seeds like bright conditions, rarely is direct sunlight good for seeds, however they prefer bright conditions and wattages of 25-50W per square foot are ideal for fluorescent, LED or HID lighting, also ideal are greenhouse conditions. When using artificial lighting place the seedlings as close to the light as possible without overheating them, as a general rule if you hand feels uncomfortable with the warmth of the light the seedlings will too.
Growing from seed is the easiest way to produce a large amount of quality cactus in the least amount of time for the least amount of money.
I will return to this topic and continue to add and address myths, feel free to contribute or ask questions!
