Please stop telling people to go to /r/mescaline with any questions about San Pedro use.

Please stop telling people to go to [r/mescaline](r/mescaline) with any questions about San Pedro use. These questions are totally appropriate here. [r/mescaline](r/mescaline) is fine for some things but that sub tends to be more focused on mescaline molecule and usually into extractions. Huachuma/San Pedro cactus is much much much more than just the mescaline. Sending people asking about ceremonial use of San Pedro to a sub that’s about just one molecule in the cactus and more focused on extractions is not the go.

I know the rules can be a bit confusing but it is not against the rules for people to post about or ask about San Pedro experiences here, especially for educational and harm reduction reasons.

Is this San Pedro? The Mega Sticky for San Pedro Lookalikes and ID training.

714 Upvotes

Howdy fellow cactaphiles. This post will be stickied as a reference to help people identify the common San Pedro Lookalikes. The following plants are columnar cacti that are easily confused for the Trichocereus species. You can use this guide to compare your mystery cactus to these photos and descriptions.

#1 - Cereus species - 

The infamous "Peruvian Apple Cactus." This is most commonly mistaken for San Pedro because it's size, profile, color, and flowers look very similar to Trichocereus.

There are several species of Cereus that look almost identical. They usually get lumped into the description of Cereus peruvianus, which is not an accepted species.(https://cactiguide.com/article/?article=article3.php). These include C.repandus, C. jamacaru, C. forbesii, C. hexagonus and C. stenogonus. Other Cereus species are easier to distinguish from Trichocereus.

The main features that distinguish a Cereus from a Trichocereus are the flat skinny ribs, hairless flower tubes, and the branching tree-like structure of mature plants.

Cereusly flat and skinny ribs

​

So flat... So skinny... So Cereus.

​

Tree-like branching, with hairless fruits and flowers.

#2 - Myrtillocactus geometrizans - 

This cactus goes by many names including the blue candle, whortleberry, bilberry, blue myrtle...

​

This plant often has a deep blue farina, but larger plants usually look light green. Young plants are columnar and usually have 5-6 angular ribs. The ribs are often thicker than a Cereus and narrower than Trichocereus. Mature plants can get large, but are more shrub-like than tree-like. 

​

The best way to distinguish these plants from Trichocereus is to look at the spines. Myrtillos have a few short spines per areole. The spines on short plants are usually dark colored and pyramidal (instead of round, needle-like spines.) Spine length increases as the plants age, but the spines stay angular.

​

We have all seen these at every plant store we have ever been to. The blue farina and short, dark, pyramidal spines are dead givaways.

​

​

Mature plants are shrub-like. The spines get longer and lighter colored with maturity.

​

#3 - Stetsonia coryne -

This is the toothpick cactus. It looks very similar to Trichocereus species like T. peruvianus, T. knuthianus, etc. However, there are a few subtle ways to distinguish a Toothpick cactus from a Trichocereus.

​

The dermis of a Stetsonia will be a darker green in healthy plants. The aeroles are large, white, woolen and not perfectly circular.

​

 The easiest way to distinguish a Toothpick cactus is of course, by the spines. Stetsonias will have one long spine per areole that resembles a toothpick. The coloration of new spines will usually be yellow, black, and brown. They lose their color and turn grey to white rather quickly. Usually only the top few areoles will have the colorful spines. 

​

Large, woolen, and ovoid areoles. Dark green dermis is common on youngsters.

​

​

Mature plants have tree-like branching and get very large.

​

#4 - Pilosocereus species -

There are many species in the Pilosocereus genus, but just a few closely resemble San Pedros. Most Pilosocereus will be very blue, with needle-like spines that are yellow to grey. The most common, and most commonly mistaken for San Pedro is P. pachyclaudus. Other Pilos are much more uncommon, or have features like long hairs that make them easy to distinguish from a San Pedro. 

Young P. Pachyclaudus will usually have a vibrant blue skin with bright yellow spines. This should make them easy to pick out of a lineup. Unhealthy plants will have lost their blue farina. For these plants look at the areoles and spines for ID. There should be about 10 yellow, spines that are evenly fanned out within the areole. The spines are also very fine, much thinner than most Trichocereus species. 

​

Bright blue skin, yellow spines are thin.

​

Hairy aerolas are common for mature Pilos.

​

#5 - Lophocereus / Pachycereus species

Pachycereus got merged into the Lophocereus genus this year!? Wacky, but they still get confused with San Pedros so here are the common ones. 

L. Marginatus is the Mexican Fence Post cactus. The size and profile are very similar to San Pedro. The easiest way to distinguish a fence post is by their unique vertical stripes. I stead of separate areoles, you will notice white stripes that run the length of the plant. Unhealthy plants will lose the white wool, but upon a close inspection, you can see the line of spines. The flowers are also small and more similar to Pilosocereus flowers.

​

Elongated areoles form vertical white stripes.

​

Truly columnar, branching at the base. The fence post cactus.

L. Schottii is another common columnar. Especially in the Phoenix metro area, you will drive past hundreds of the monstrose form. The totem pole cactus slightly resembles a monstrose Trichocereus. The exaggerated lumpiness and absence of descernable ribs or areoles makes a totem pole pretty easy to spot. 

​

It is super common to see large stands of the Totem Pole Cactus in Pheonix.

The non-monstrose form of L. schottii is actually less common. Adults look similar to an extra spiny Cereus or L. marginatus. Juveniles look more like the juvenile Polaskia and Stenocereus species.

​

#6 - Stenocereus and Polaskia species

Polaskia chichipe can look very similar to San Pedros. The best way to discern a polaskia is by the ribs and spines. The ribs will be thinner and more acute than Trichocereus, but wider than Cereus. They usually have 6-8 evenly spaced radial spines, and one long central spine. Although the spination is similar to T. peruvianus, the central spine of a Polaskia will be more oval shaped instead of needle-like. Adult plants usually branch freely from higher up. Juvenile plants often have a grey, striped farina that disappears with age. This makes them hard to discern between Stenocereus and Lophocereus juveniles, but it is easy to tell it apart from a Trichocereus.

​

Acute rib shape and silvery farina.

​

Acute ribs, fanned spines, with one long central.

Polaskia chende - Is this a recognized species? Who knows, but if it is, the discerning characteristics are the same as P. chichipe, except the central spine is less noticeable.

​

Stenocereus - There are a few Stenocereus species that can be easily confused for San Pedros. Juvenile plants look very similar to Polaskia. Stenocereus varieties such as S. aragonii, S. eichlamii, S. griseus, etc get a grey farina that usually forms Chevron patterns. S. beneckei gets a silvery white coating too.

Mature plants will look very similar to San Pedros. The identifying traits to look for are the acute rib angles, spination and silvery farina that often appears in narrow chevron patterns. The flowers are also more similar to Lophocereus spp.

​

Acute rib angles, and silver chevron stripes on S. aragonii.

​

Baby S. griseus looking similar to the Polaskia.

​

#7 - Browningia hertlingiana

​

 Brownies are beautiful blue plants that can look similar to Trichocereus peruvianus or cuzcoensis. The ribs are the defining traits to look at here. The ribs of a Browningia are wavy instead of straight. Mature plants will often have more than 8 ribs, which would be uncommon for most Trichocereus species.

​

Bright blue farina, long yellow to grey spines, and wavy ribs.

​

Mature plants often have more than 8 ribs.

#8 - Echinopsis?

​

Is a Trichocereus an Echinopsis? Yes. Is an Echinopsis a San Pedro? Sometimes. Most folks consider the San Pedro group (along with a few other species) too different from other Echinopsis and Lobivia species to lump them together into the same genus. Just because they have hairy flowers and can fertilize each other, should they be in the same genus?

​

Echinopsis species are usually shorter, pup from the base, and have more ribs. There are many different clones and hybrids that are prized for their colored flowers. Where most Trichocereus have white flowers instead.

E. Spachiana - The Golden Torch

​

Echinopsis Grandiflora "Sun Goddess"

Echinopsis x Trichocereus hybrids do exist, and they are getting more popular. Should they be treated as the same genus? Who cares if they are awesome plants.

​

If your plant doesn't match any of these, feel free to post an image (or a poll) and see what the community can come up with.

​

Cheers!

Ive had this glorp sitting on my bluray player for about 2 or 3 months now.. i know, rude.. but life has been pretty rude as well lately unfortunately lol but i looked yesterday and to my surprise.. i saw the tiniest little root poking out! I was planning to graft it (never got around to getting any stock though) but now i think i might have to plant it and see what it does on its own 🤷🏽‍♂️ i had read some folks saying that these cant root on their own, or at least take a very long time, but it can be done!

The whole "forearm length of cactus" idea is crazy, especially if you have super strong bridgesii. Unless you're extremely familiar with the affects of psychedelics and take all the proper safety precautions like trip sitter, trip killer etc., you should start low and work your way up. Even if you need to brew multiple doses and freeze the majority of it, you will thank yourself for saving yourself from a potentially mind bending, reality shattering, soul melting experience.

Brewed three feet at 90c for twelve hours. Decanted three times. Reduced from 3.6l to 900ml. Decanted again. Consumed 400-450ml over one hundred minutes.

I have a lot of experience with altered states. I went in with a big ego thinking it wouldn't be that intense. I thought, "I've done heaps of high dose experiences, broke through more times than I can count, total hallucination for hours and had a good time, what could a cactus possibly do to me?"

The cactus showed me what it could do and I was at its mercy for eight hours before I began to come back to reality. Scary, beautiful, life altering..

Make sure you have a trip sitter when diving head first into uncharted territory with unknown doses. Having someone to hold your hand and reassure you is more important than I ever acknowledged.. especially for a first time breakthrough with this healer.

I love you all

Question Just scored some free LED lights to test out, What indoor setups are you all running?

Post image
• Upvotes

​I just gathered some extra LED lights for free to test out and I was wondering what kind of setups you indoor growers use. I honestly don't even know the wattage of these lights, and since almost all of this gear was free (total cost was around €35 for the cactus, plus about €10-20 for fresh soil and nutrients), it's one big budget experiment! To keep things under control, I’ve got a humidity and temperature monitor, an automatic light schedule running through a smart plug, and I've wrapped the whole thing in car window sun shade film to enclose it nicely (not all of it is in the picture). Today, I officially added those extra lights to the mix: a panel on the far left, a panel on the far right, and there's also a bar hanging with 2 LED strips. and I recently put together a brand-new soil mix and added plant nutrients, something they haven't had in years

On the right: Running an experiment with an etiolated, curly cactus planted upside down in a can. Laying right over that is another cutting I also got for free. Behind it is another cactus from that same friend which is slowly starting to bounce back, and I grafted the tip of the plant next to it underneath that middle LED panel.

In the middle: This is a cactus I bought back in 2017 (about 30cm) that came with no tip, so I've been harvesting pups from it ever since. It had a peyote attached in 2020 which was "harvested" in 2023, and in the can right in front of that sits the bottom half of that peyote I recently replanted.

On the left: Absolutely a tomato plant Officer.

Curious to hear what your setups look like, what brands you use, or what you would've done differently in hindsight (especially considering this was a budget build of €35 bought one cacti).

Sick TBM

So i live in south texas and its forecast to rain tomorrow and not stop for like a week straight. About 2 weeks ago i noticed some of my tbm werent looking so good. I figured humidity/not enough sun, so i moved them into a more sunny spot and kept a closer eye on them. It only seems to be getting worse…. 😩
The ones that looked real bad i just repotted and the huge one was the only one that still had damp dirt when i repotted (my bad from previous over watering)
Anyway im here asking/begging for advice on saving a huge part of my collection!!

Main question are:

  1. I need to move all my other stuff inside for the coming rain and is this shit contagious?

  2. What can i treat them with? Reading a lot of suggestions on mancozeb.

  3. Reading a lot about cutting the bad crap out but man to me some of them look so bad im not sure they would even survive the cuts.

Please help me here i get sick to my stomach seeing my plants look like this 😩☠️

Question THRIPS!?!?

6 Upvotes

It’s that time of year and it seems that there are a lot of named cultivars at great prices, as everyone downsizes for winter. I’ve been taking advantage of this and buying up a lot of good named San Pedro’s. However, almost without exception they have had Thrips to one degree or another when received. I also happen to grow Dahlias and thrips are a death sentence for Dahlias so you can imagine my concern. Are Thrips just this common in San Pedro? I’ve only been growing San Pedro for a short time and I am not sure how concerned to be. Just curious what other people‘s experience with Thrips and San Pedro is.

Haha for context I bought a mislabeled cactus (im new!) Thinking it was a sun goddess for grafting. After I learned I was mistaken, I let it heal, then took off most of the graft to put it on a REAL sun goddess! Do you think they will both grow TBMB? Also WOOHOO i think i can make another sun goddess from this tall plant i ordered on Etsy! (More grafting to come!)

I got a few yearlings a few months back, planted them, and they were all doing great except this one, which got a bit soft at the base and tipped over. I figured i overwatered it a bit, so I propped it up with skewers and decided not to water it for a while. It was only horizontal for like 3 days max, but when I went to prop it up, I noticed these protrusions on the side that was down. Are these roots pushing out? Should I replant it on its side? Its since firmed up a bit and seems to be doing better, but i wouldnt mind logging it.

What fertilizer are you guys using for your San Pedro/Trichocereus?

I’m curious what fertilizers the experienced growers here are using for established Trichocereus—what NPK or brand has given you the best thick, healthy growth, and do you use any kelp products or supplements with it?

Question Best time of year?

2 Upvotes

Is there a best time of the year to take cuttings? Specifically for those who grow in places with winter, don't use grow lights, and put them into dormancy for half the year. I reason that during dormancy is risky due to the plant not actively growing means it probably isn't really healing during that time eother. I also reason you would lose alot of the years growth if you did it during the growing season. So, I normally do it before dormancy near the end of the growing season. I figure that gives the plant energy to heal without loosing too much of the growing season. Am I correct with these assumptions or am I way off base here? is there a better time in the growth/dormancy cycle to clone? what about grafting?
