Dutch pilot experiment: LEGALLY growing organic female hemp flowers high in CBD

[karl.uk]

Hi Cannabidiolator,
Interesting what your are doing, what plant strain are you using, as for ourselves to grow it LEGALLY, it would need to be a strain that was on the EU approved seed list ??
It is of interest to grow an all female crop, and at present, it requires lots of labour in extracting the males once they show themselves. However in future it will be achieved by feminzied Finola seeds, which will reduce labour to get an all female crop. (Higher CBD levels) Do you also have a website or contact details so we can see what your are doing ?
Thanks
Karl.

Hey Karl,
Did you consider that producing your own Finola seeds (feminised or standard) is already against the law? Maybe you can ask for an exception at Finola.fi (they're the ones to decide cause they hold the exclusive rights for Finola breeding)?

Colorado Hemp situation

Colorado Hemp situation

Here some interesting snippets from an interesting article (February 2015) on the peculiar hemp situation in Colorado.

Issue: There is very little industrial hemp seed in Colorado to support a growing interest in
industrial hemp production. The seed that is available is not certified to produce plants with a
THC content at or below 0.3% thereby placing additional crop risks on the farmer. In addition,
there is no research as to which industrial hemp varieties from other countries will function well
in our climate putting further crop risk on a farmer using untested imported seed.

Solution: Develop certified seed varieties through a partnership with the Colorado Department
of Agriculture and Colorado State University.

.....
The only ways to improve seed availability of certified varieties so that THC, quality and
agronomic characteristics can be predicted, is to develop varieties within the state and import
industrial hemp seed and test varieties from other countries. Because industrial hemp is
regulated by the CSA, importation of industrial hemp seed requires a Drug Enforcement
Administration (DEA) registration and import permit. To date the DEA has been very reluctant
to grant registrations and import permits to import viable hemp seed.

OO,
Good point, will check it out !

Great Thread! It´s good to see other people doing a great job!
Are you guys attending the EIHA in may? Would be great to catch up and have a chat!

all the best from Berlin!

Hi, I am attending the EIHA conference! Very excited to be going! Looking forward to seeing you!

Hi All were attending the EIHA conference, look forward to seeing you all.

Hi All,
Just a quick one......... THC is the band / controlled substance in Cannabis which makes it a scedule 1 drug according to the home office.
However to get THC, you have to heat up THCA (Generally by smoking) from the Cannabis plant. Therefore lets say you produced a cannabis plant with 7% THCA & 7% CBDA, you juiced it and consumed the juice, would you be breaking the law. No THC in it ???
Your thoughts Guys.

 

[Only Ornamental]

The law applies to everything which contains THC in it's structure: THCA, THC acetate, THC methyl ether, and any other possible modification unless it's proven to be inactive and can't be used as precursor (and isn't derived from THC itself). It may not be written exactly like this but every judge will treat it that way.
Besides, cannabis plants synthesis only THCA and hence all the weed in the world would be legal according to your logic...
Oh, and then there's the EU law that you need a CBD:THC ratio of 2 or bigger.

 

[karl.uk]

OO,
Points duly noted.
Is there away to extract the varies chemical compounds from Cannabis, but getting rid of all the THC ??
As we are aware there are 483 different chemical compounds in Cannabis. Each of these having various traits.

These compounds have varies flashpoints, thus
a. Tetrahydrocannabinol (THC) Boiling point: 157C / 315 degree Fahrenheit.
b. Cannabidiol (CBD) Boiling point: 160-180C / 320-356 degree Fahrenheit.
c. Cannabinol (CBN) Boiling point: 185C / 365 degree Fahrenheit.
d. Cannabichromene (CBC) Boiling point: 220C / 428 degree Fahrenheit.

Would it be possible to produce a product that has below 0.2% THC in the final product, by heating it up to a temperature point of 159C /319 degree Fahrenheit, to ensure the THCA then THC compound are driven off. This will not damage or drive off the valuable CBD, CBN or CBC. This liquid, will then be reconstituted with either distilled water ( for juice applications) or olive / hemp oil ( for oil applications )

Your thoughts guys.

Why not take a look to CO2 extraction?? High heat will produce poly aromatic carbons like Benzo(a)pyrene which the EU has a mrl of 10ppb.

BTW what's the use of CBD only extracts??

Keep on growing

As Mexi said, fractioned distillation using supercritical CO2 is a way better strategy.
Fractioned distillation at 150°C or whatever sounds like something doomed to fail.
Otherwise, use column chromatography (open, flash, or MPLC) to either enrich the extract in the wanted constituent or 'derich' in an unwanted one. Though you'd still need to work with possibly prohibited starting material...
And acceptable levels in preparations (food, cosmetics etc.) are likely different than those of what you are allowed to grow.

Hi all!
Very intresting thread!
I'm an hemp grower from the Hemp Farm Tortoreto, an italian hemp farm in central-italy that grow hemp and make food products.
Last year we planted Futura-75, and this year from a german replicator of certified EU approved seeds, we ordered Uso-31 and Futura-75 for food destinations and Finola to make essential oil, CBD oil and flowers, also for beer.
We are cooperating with the university of science and technical supply and one of his prof. of chemistry to make that also with a CO2 supercritical machine.

Do you have measured the increase of the THC level % in the flower if is more than 0,2%?
I still believe that with our micro-climate in Italy, in Abruzzo, the amount of cannabinoids will be higher.

if you would to take a look at the plants we're on facebook at www.facebook.com/hempfarmtortoreto

Dear HFT,
Why do you want to grow Uso-31 and Finola in central Italy? These are good for northern climates and do also well in central Europe but for Italy... growing Finola might be tricky and you would have to figure out somehow when to saw them.
Also, the southern ecotypes which should grow nicely in your region, contain more and better smelling essential oil. Why don't you grow for example Carmagnola? Too tall?
Besides, all EU registered varieties are very unlikely to produce more than 0.2% THC even under perfect conditions. Most of all, Uso-31 is a nearly cannabinoid-free variety.

You should contact the CRA-CIN Centro di Ricerca per le Colture Industriali, Via di Corticella 133, 40128 Bologna, Italy.
One of their publications could be interesting for you: CLICK.

@HFT Good to hear about your project! I looked at the photo's on FaceBook looks great! Growing super tall, nothing like Finola. How did you harvest and process your crops? And is that you hemp wood, and is so how did you do the decortication?

As for the strain choice I second Only Ournamental.

Maybe you want to contact Dr. Gianpaolo Grassi (CRA-CIN, Industrial Crop Research Center, Italy).

He's presenting at EIHA in May on the evaluation of CBD content of different varieties and environment conditions to have high concentration of cannabinoids in the plants. He is based in Italy so...

Nice photos but why did you choose Finola for the essential oil???

Keep on growing

 

[Santalum]

Great thread! It is possible to check out cannabinoid profiles of varieties like Finola but you could be almost certain the parental feedstock for that analysis was from a fertilized mother. Is there any analysis in the public domain of a sensimilla grown Finola or other higher CBD producing hemp cultivar yielding cannabinoid profiles? Shouldn't this be THE most important question in the world of CBD production? I'd be moving hemp production to the country with the most liberal attitude to attitude to hemp production, then the lowest labour costs and then finally the weakest currency. Anybody want to list a model and make a motsa? Ha!
But in all seriousness, sensimilla hemp is the game. Plucking males is the only way forward? Cheap labour necessary to bring the cost of CBD down. It is simply ridiculously priced atm.

The problem in Europe is the low/zero THC craze and as the enzyme CBDA synthase produces for whatever reason between 5 and 10% THC, all approved varieties are unfavourably low in CBD as well and without a 'miracle' plant or gene technology there's for now no way around this pothole ;( .
