CBD Blitz: Find a high-CBD low-THC mother, from seed, in only 3 weeks

Are you growing out your thundstrucks? Sounds like you found something good. Interesting enough, elsewhere on this forum, someone was complaining about the results from their Sin city thunderstruck. In your case, 1 CBD strain out of 4 showing up with no thc does not really validate a seed vendor, but by the same token, I'm not saying there is anything wrong with the vendor. There's just something wrong with the picture
Im guessing you mean the ["Thunderstruck Is A Fraud"] thread hehe... that's just one very fussy person, MrBluejeans, who seems to assume every bean should = some ACDC clone from seed ... yet even his results were still pretty good

First he posted three lab test results:
#1 - 0.14% CBDA, 3.42% THCA
#2 - 2.03% CBDA, 0.65% THCA
#3 - 0.12% CBDA, 2.03% THCA


1 out of 3 isn't the end of the world. He then showed a TLC plate:
#1 - ~1:1
#2 - ~1:1
#3 - THC only
#4 - ~1:1


3 of his 4 TLC lanes show high CBD, yet he goes back to his seedbank, Herbies in this case, and actually gets a refund from them!

btw yes im growing one Thunderstruck, one CBD Therapy, and two Candida's - the ones that showed up in TLC as no THC but high CBD, essentially all "hemp" lol. I'll cull to my favorite one after flowering them out. I still have 4 or 5 more Thunderstruck seeds left to germ. The Thunderstruck started out very mutant-looking but has now settled into regular sativa growth. The other three are hybrid looking.

it's easy, just have the Dept of Agriculture rep come out and test your crop. You see, there other ways to skin this cat, you just need some little legal palm grease
I don't live in a legal state, I don't live in the USA (this is an international forum), I don't have a hemp growing license. For the vast majority of people here, no, that is not a way to skin this cat!

If I can get seeds would you be interested?
very kind offer thankyou, i wouldve been keen just over a year ago but i dont have an address to get them at the moment. No real need now though as ive got these 4 high CBD/low THC seedlings, and still a couple dozen more seeds to test at a later date so i've probably already found what i was looking for :) cheers again though!

Nice, which are you favorite so far from the 3 strains? Which one of you the ones you have grown so far had the most resin?

dogcat,
(btw just so there's no confusion, those THCA/CBDA lab tests i posted weren't mine, i was quoting another Thunderstruck grower)

But if you meant my ones, from the CBD blitz ive got one sativa-dom Thunderstruck (started out very mutant looking but settled into normal growth now), one hybrid-looking CBD Therapy, and two hybrid-looking Candida ... all effectively hemp, lol. Theyre all doing well, and I'll very soon take clones to see how they flower - yield, duration, ease, virility etc. But I can't really make any decisions about which is best until I get some feedback from the guineapigs, that's still two or three months away though. Will most likely cull to just 1.

yes, I meant yours, thanks. I'm very curious about leaf and plant structures of the cbd strains, resin, yield etc. I saw a video with the Thunderstruck, and it looked really sativa! Some of these strains look like a bit of a horror show to trim. I was impressed with the resin on the candida, looks like a really nice strain. I've also seen some videos with the dancehall strain, and she looked quite nice.

just re Thunderstruck, from the 5 i grew 4 of them looked like regular hybrids, while one (which ended up being high CBD/no detectable THC in the TLC) looked like a very lanky 'pure sativa' with weird curly serrated leaves giving it a mutant impression, but it's since settled into regular growth now and no longer looks mutanty

In just 3 weeks, you can go from ungerminated seeds to finding a mother with the cannabinoid profile of your desire (high CBD/low THC for example). Allow me to explain ...

It can be incredibly disheartening to spend several months growing a plant that was advertised as "high CBD low THC" only to find it has plenty of THC and no CBD. It's especially disheartening if you or your friend/family member are a medical patient with neither time or money at your disposal. I've been there.

However, if you're just looking to find a high-CBD/low-THC plant you don't need to grow to full harvest to determine the result, because the cannabinoid profile is genetically established, and the sensitivity of Thin Layer Chromatography (which people can do at home) means we only need to grow the plants for 2-3 weeks (from seed). No flowering period required, just 2-3 weeks of seedling/vegetative phase. A CBD blitz.

And because we're only dealing with small seedlings and such a short time frame, this makes it possible to quickly grow out seeds, and while a small grow chamber may only be large enough to bring 1 adult plant to harvest, it would still be big enough for a dozen or so seedlings. Then after 3 weeks you simply do the chromatography tests, keep the plant(s) you want and cull/discard the rest.

You only need:
  • Seeds
  • Small pots (or plastic/foam cups
  • Grow chamber or sun or sufficient lighting
  • Thin Layer Chromatography equipment (see [my DIY TLC link])
  • 2-3 weeks time
Method:
  1. Germinate the seeds.
  2. Grow for 2-3 weeks (until they're big enough to take a leaf cutting).
  3. Cut a trifoliate leaf off each seedling.
    Use gloves to prevent cross-contamination of samples.
    Wrap individually in aluminium foil.

  4. Decarboxylate for 60 mins @ 125°C/257°F, to convert THCA to THC etc
  5. Use Thin Layer Chromatography to determine CBD and THC levels in each one
  6. Keep the good ones, cull/discard the rest.
Criticism:
Ok, after 3 weeks you won't know much about the plant (you won't know how long it flowers for or what her flowers are like, and if it's a regular seed you won't know if it's male or female, etc). In other words, it's pretty early to say "yep, you're gonna be my mother plant!". That's not what this test is for though. This test is to establish the cannabinoid profile of the plant, and it does that beautifully, so it's a great way to FIND THE BEST CANDIDATES for your potential mother.

In the next post I'll show an example from start to finish ...
Yeah, high CBD stuff is what is taken the world by storm because it's completely non-psychoactive!

No ... it's because of the medicinal effects. Being non-psychoactive however is giving it another "venue" to find its way to the public that THC cannot do (under current outdated laws)

Absolutely! CBD has been proven to help as a Digestive Aid, combats tumor and cancer cells, psychosis disorders, inflammatory disorders, analgesic, neurodegenerative disorders, Depression disorders, anxiety reliever and even prevents many types of seizures! It’s been called “miracle drop” that is sweeping through the united states.

How do you feel about THCa
The two most well-known cannabinoids are THC (tetrahydrocannabinol) and CBD (cannabidiol). For decades, researchers have known that THC is responsible for the famous cannabis high.

But until recently, very little was known about the effects of CBD. We now know that CBD can serve to balance the effects of THC, and provides a range of symptom relief and medical potential.

The plant contains very little THC. It only gets converted from THC-A during curing or heating.
In other words, full spectrum extraction is superior to CBD oil as it has a wider range of cannabinoids while still not psychoactive.

@PhenoMenal have you considered trying dinamed cbd plus? from what I understand it is supposed to be a more stabilized dinamed and higher cbd advertised in the 15-20% range along with a 30:1 CBD:THC
It would be interesting to see if dinafem got it right the second time or not. So far it looks like candida seems to be the winner out of the ones you tested. 2 for 2 is not bad when compared with the rest of the strains
It seems to be so difficult to get a functional cbd pheno of any strain by seed, and especially so for high cbd low thc.
Industrial hemp is looking more and more interesting. Have you considered growing that instead?
https://highalpinegenetics.com is claiming 19.56% CBD on their strains. Other industrial hemp seed companies claim similarly high CBD % but mostly only sell in bulk for farmers looking to farm many acres and only sell seeds by the 1000's.
Nice work!

sorry i meant Candida is the one i had best results from. I had mixed results with the original Dinamed. But keep in mind i only grew a couple of seeds from each - that's not a population we should derive any statistics from! but as I havent tried the Dinamed Plus so cannot comment on that, hopefully they've found some stabilisation. I am not growing now so not in a position to do more testing beyond my last grow.

Candida looks like a good proposition for those looking for high CBD low THC. I was suggesting the dinamed plus if you were still doing testing. sorry to hear that is no longer the case. I still wonder how the stability of the industrial hemp strains out there compare to the questionable stability of seeds from seed banks.
