Sin City Seeds Thunderstuck is a Fraud

Yes! ALL cannabinoids are revealed by Thin Layer Chromatography (thanks to the Fast Blue B or Fast Blue BB dye, in combination with an appropriate eluent that separates the cannabinoids)

[NOTE: just to clarify, the TLC images shown in my reply here are not of Thunderstruck, but other various strains, just to demonstrate some cannabinoid variance in tests]

One of my previous analysis images in my Thin Layer Chromatography thread (see signature [link]) was from a strain which turned out to be very high THCV -- I had no idea until i analysed it! but you'll see it's very clear:

If there were any CBD (there isn't) you'd see it as a BRIGHT ORANGE dot immediately above the BRIGHT RED dot of THC. THCV stands out as a DARK CHERRY RED immediately below the THC dot.

When you compare this to my other analyses you'll see it sticks out like a sore thumb, and it was a pleasant delight to see because THCV is usually low or non-existent in most strains.

Compare it, for example, to a high CBG strain (golden spot) ... you can see this strain has very low but still detectable levels of THCV between the golden CBG spot and the large THC spot. This is a very significant level of CBG...

Just to be clear about how CBD looks with this eluent, it's the BRIGHT ORANGE dot ABOVE-but-hugging the BRIGHT RED dot of THC ...

In this analysis you can see the Cinderella99 is just full of THC (as to be expected), whereas the Dinamed is approx 1:1 CBD:THC ... both also have healthy levels of CBG and CBC, nice!

There are a couple different TLC kits you can buy, but they don't come with many tests (then you need to buy some refills), so I sourced all the components individually, which i've listed in my thread.
But certainly the easiest way to start is just buy one of the existing kits, then you can still source the refill items yourself, but won't need to buy any of the initial parts. AlphaCat's kit is the best one to my knowledge - I haven't used it, but judging from their videos and good documentation etc they seem a professional outfit.

Feel free to google for other kits though, they're all pretty much the same ... the only 'special' thing required for TLC of cannabinoids (as opposed to say, TLC of fountain pen ink) is 1) the use of the Fast Blue B or Fast Blue BB dye to stain the cannabinoids so we can see them, and 2) a suitable eluent for separating cannabinoids (eg. chloroform, or 4:1 hexane : diethyl ether).

WHAT THE FUCK?! This is either Legendary trolling of Epic proportions, or a crazy ass coincidence.

OP fucks up and does not understand that it is “pheno”, short for phenotype, and instead believes it’s “Plant Physiological Phenomena” (a term for... never mind ), shortened to “phenom”. Then, the thread is schooled by username @PhenoMenal , who also just so happens to have joined RIU within days of OP... in 2009!

Either way, my mind is befuddled, and thank you PhenoMenal for your contribution.

Hi Everyone,


My goal is not to stir a new controversy about whether Thunderstruck is a fraud or not.

No, my intent is just to share my thoughts about, and my experience with Thunderstruck from seeds.



Of course, plants are living beings, and as such may display very different traits from one individual to another.

But Thunderstruck is not just any regular plant. Thunderstruck is supposed to be the result of a selfed plant, to reliably yield, from seeds, according to the breeder’s claim 16-22% CBD and 1-2% THC.

Anyone reading this claim is led into thinking that, any Thunderstruck seed picked at random, will produce at least about 16% CBD and a maximum amount of 2% THC.

Well, this is not what I have found to be true (see down bellow documents, from 2 different plants).

Breeders should be legally liable when asserting such claims... especially when their plants yield opposite numbers to those claimed.

Such occurrences are telltale manifestations that something is fundamentally wrong with SCS Thunderstruck seeds…




When I contacted Sin City Seeds to show them the HPLC analyses results of, raw, Thunderstruck flowers (cut @ 63 days of flowering), they did not seem surprised at all, and replied :

-“(Thunderstruck) still technically being a hybrid, such variations were to be expected”.

And when I suggested they should discontinue Thunderstruck until further fine tuned and stabilized to live up to their claims, they just apologized and said that :

-“Thunderstruck was here to stay for the long term”.

Very disappointing attitude for professionals of the cannabis industry… who must be very well aware of those issues, but still supply the market with this “special, solid genetics” as SCS put it.




What follows is the conclusion I drew from cultivating this plant.


Growing Thunderstruck from seeds, may not be a good option when or if :


- One needs consistently high CBD and little to no THC in each plant.

- Medicating is the primary purpose, for THC and CBD rates will wildly vary from breeder’s numbers.

- Not prepared or willing to indulge too much time in a pheno hunt, and spend significant amounts of money in lab tests.




With hindsight, if I could somehow go back in time and venture to give myself a piece of advice, I’d probably say :

- :“ If you need a THC free strain (or close to) with reliably high CBD percentages, but cannot get hold of a certified high CBD clone, then do not even consider buying seeds of Sin City’s Thunderstruck.

You would not only end up wasting time and money, but you’d also be in for big disappointment”.



I do not claim holding any truth whatsoever, neither do I aim to convince anyone of anything. Everyone’s free to believe whatever she/he wants, and do whatever she/he deems fit.


Except for the 3 instances where I cited Sin City Seeds, these words and thoughts are mine and mine alone.

This is what my personal experience with Sin City’s Thunderstruck from seeds inspired me.


I wish breeders were more trustworthy persons. But I guess you cannot expect much from those too eager to take advantage and make huge profits from the last trends.

I just tested 16 seedlings, 5 of which were Thunderstruck, with Thin Layer Chromatography ... 4 of them were approx 1:1 CBD:THC, while one was CBD-only. See [link] for results.

My conclusion: No, Thunderstruck is not a fraud (re the thread title), it seems CBD is plentiful and in high quantity in most seeds (all 5 in my case, and even the OP posted thin layer chromatography showing he too found CBD), but don't expect every seed to result in a killer ACDC phenotype!

Here's the thin layer chromatography of the 5 Thunderstrucks, just showing the CBD (orange on to)/THC (red on bottom) bits ...

Again VERY healthy levels of CBD in ALL 5, although only one of the five is "CBD only".

So yes I have to say Thunderstruck is the real deal. It is not a fraud (and this thread is ridiculously and falsely titled) ... but it is a selfed S1, and Mother Nature and the genetic history of the strain determine the outcome, so we need to accept that not every seed will be like AC/DC.

Thankyou Sin City for this release, and I now have confidence in my other 4 Thunderstruck seeds
