"Null Thc" genetics

Does anyone here have access to biomass grown from the new 0 THC strains I’ve seen around? Or can anyone confirm these genetics/ biomass exist and actually contain 0 THC? Need some for a new project.

Closest thing to no thc I’ve seen are cbg strains that are well stabilized. What have you heard about a 0 THC strain? I’m skeptical it exists but it would be neat to see.

From my research it hasn’t been cultivated yet but should hit the market soon. Its looking like they used CRISPR to remove the D9 and THCA markers .

My understanding is the CBG strains from Oregon CBD are mutants that don’t produce the THCA synthase enzyme. That being said I’ve seen THC/A present in some amount in most CBG flower COAS and almost always in the concentrate. So not sure even that is truly 0 THC, but about as close as you can get for now as far as I’m aware.

Is this for Japan or something like that?

This is something different, SIU Carbondale has set up some awesome shit. There’s modified genetics that don’t produce any of the THCs and at this point sounds like designer flower is about to be the rage. Why else would we have posts be asking about interest in high THCv flower that would be compliant? It’s already being implemented.


sounds like bunk ass weed to me. check out mexico because their weed was always low thc. Is the reason for this crap due to some states laws?

It’s hemp…

ive never tried hemp derived products. here its .03 thc limit i think.

@seth from OregonCBD discussed it during sampler training last year. I’ve been trying to get it called No-binoid once he turns off all the noid.

No-binoid. Brought to you by the makers of fukitol.



A company called Gencanna claimed to have ND thc genetics a few years back but nothing ever came of it as far as I know.

That would be cool if we could turn off cannabinoid production but an over expression of w/e gene cause terpene production.

The boss just picked up Blue Kross, 0 thc
Ultra diet weed.


Any plans to extract or concentrate it, please let us know if it’s still 0 THC!


Monsanto incoming :rofl:

Do you have any more info about this strain and where he got it?


I’ll find out for you.


Will there be biomass available from this any time soon?

No, and yes (regarding chemotype V, cannabinoid-free cannabis). I haven’t heard of a CBD-rich or CBG-rich, THC-free chemotype. Still, it should be possible to create them using CRISPR genetic engineering (refer to the references in this post). Traditional breeding may be a potential route, but I’m doubtful it’s possible to only produce null THC while other cannabinoids and terpenoids are unaffected.

Etienne de Meijer used cannabinoid-free fiber hemp (Ukrainian cultivar USO-31) in a series of breeding experiments in the early 2000s. He was the lead author of a paper describing the experiments and discussing chemotype V cannabis (cannabinoid-free) published in 2009, funded by GW Pharmaceuticals.

I believe de Meijer, David Pate, and Robert Clark created the first cannabinoid-free drug cannabis by breeding the cannabinoid-free fiber hemp plants with high THC drug cannabis while working for Samskunkman’s (David Waston) company Hortapharm BV. GW Pharma aquired all chemotype plants and genetic material from Hortapharm BV in the late 90’s.

When de Meijer germinated 23 USO-31 fiber hemp seeds, he found five cannabinoid-free plants (21% of the seeds). Which he used to research the so-called “cannabinoid knockout factor” later attributed to a “cannabinoid knockout gene.”

de Meijer and GW Pharma were granted a patent in 2008 for cannabinoid-free clones and their use as reference plants: A novel reference plant, a method for its production, extracts obtained therefrom and their use (WO-2008146006-A1).

Regarding processing chemotype V cannabis, solvent extraction is the best option because the capitate-stalked glandular trichomes are shriveled and probably won’t yield well with solventless. I wonder if trichomes from THC-free chemotypes are similarly shriveled. Note that female cannabis has trichome-covered perigonal bracts, not calyx (calyces), enclosing ovaries with protruding pistils.

According to de Meijer, the trichome heads on cannabinoid-free homologs of the high THC clone M3 used to produce Sativex, clones M319 and M299, are shriveled and small. Where the “original” is the M3 clone used to create Sativex, and the “knockout progenitor” is a cannabinoid-free plant grown from Ukrainian fiber hemp cultivar USO-31 seeds. From Handbook of Cannabis:

The homologues clones were selected from backcross progenies (e.g., M299 = M3 × (M3 × (M3 × knockout progenitor))) and share 87.5% genetic identity with the corresponding “original.”

I would love to see cannabinoid and terpene COA from flower and BHO. Along with lineage information.
