It is conform; but whether or not it's in the catalogue is up to you to figure out: Chose the catalogue with your preferred language HERE.Ornamental,
Very interesting, does the Alyssa strain conform the the legal requirements 0f below 0.2%thc and is it in the EU seed cataloge ?
Thanks
Karl...
Very nice plants, Dutch. I am ten days behind you. Yours are much bigger and better but very much the same variety. Mine are sticky resinous with a sharp spicy smell.
I don't doubt that sinsemilla yields more flowers. My comment was directed more at the practical matter of removing all the males from a whole acre of plants. I guess offthehook does it but an acre's worth? All it takes is missing a couple and you have a seeded crop. I can live with the seeds and we'll see about the cannabinoid content. Have you had any luck with testing?
I am very much looking forward to seeing your harvest pictures.
Interesting article, Dutch. I took away a couple of nuggets for possible immediate application. 1) harvest a bit early. It says the best oil quality is obtained when seeds are 50-75% mature. 2) harvest in dry weather, maybe several days after the last rain.
I think I'm already nearly at 50% mature seed so I'm thinking I ought to harvest pretty quickly, maybe after the current rainy spell is over.
One thing I don't get from that study is the relationship between "essential oil" production and cannabinoids.
Hi Guys.
How do you harvest your plants ? do you have any special equipment? Obviously harvesting would need to protect the flowers as much as possible ?
Dutch,
When are you du to start harvetsing ?
Any chance I can call over and see your crops prior harvest ?
....
Alyssa might be something for you: Canadian variety with ~90% females (less culling work to do ), small-medium sized and very early (still less early and a bit taller than Finola).
Many 'female predominant' varieties show > 90% females in the expensive F1 generation and ~50% in the standard F2 backcross usually sold. ...
Your welcome to visit the field karl.uk.Dutch,
I am over in Denmark in the next week or so (wind turbine buying !) therefore I could call in to have alook at your crop ?
We sowed roughly 500.000 Finola seeds (30 kg/ha) on 0,19 ha of land.Dutch,
How many acres have you planted, to get 150,000 to 200,000 females ?
I don't trust patent applications because you can claim whatever you want in a patent . Supercritical CO2 extractions made tremendous progress in the last years. It is most suited for medium to non-polar compounds such as cannabinoids and essential oil. I don't like the term 'terpenes' that much because it is a too large term. What is interesting in cannabis are mono- and sesquiterpenes which make up ~99% of the essential oil. Phytol, cholesterol and others (except vitamin A, E, and carotenoids) usually have a low pharmaceutical value or health benefit. Most of these are present in the seed oil, anyway....
In regards to the solvents. I don’t see it as a very (cost) effective method on the scale that we are facing. Supercritical CO2 doesn’t extract all the terpenes. At least according to this patent application. Check out table 1 and accompanying text.
...
As for your consecutive extraction, sounds good but not when your talking about 4,500 kg material. That still takes a lot of alcohol. And I think supercritical CO2 extraction will cost a lot of €
Do you have a reference to research stating that flavonoids are located in leaf material? As for tepenes I quote the following from the research document (page 176) mentioned in post #165. ''With the exclusion of The removal of glandular trichomes from cannabis floral material produces an ‘enriched trichome preparation’ that has a very similar cannabinoid and terpene profile to that of the plant material from which it came, but is much more potent. One major exception is the diterpene phytol, which is associated with the biosynthesis and catabolism of chlorophyll and Vitamin E, and this is predominantly found outside the trichome.
...
Hi Guys,
Very Informative and complex subject on extraction..................wow
I have been intouch with the guys at Healing Hemp in Northern Ireland, they are growing Fedora 17 this year ( they couldnt get hold of Finola seeds ) however they grew Finola last year and juiced the fresh flowers and green leaves, to give a hemp Juice. I was suprised that the CBD content of this juice was only 0.6% (they had it tested obvioulsy)
Any thought son why CBD content so low ?
Is juicing not an option for you Dutch ? the other methods seem costly and time consuming ??
Thanks
Karl...
.I think you're incorrect there. Check out the link below referring to a research document which shows that:
'' The yields of essential oils gained from non-pollinated plants were more than twice as high as those pollinated (Table 3). The scent tests did not result in a significant difference between the two different oil types. On an ordinal ranking scale from bad to excellent, all tested oils from ‘Kompolti’ were rated "very good" or even "excellent". The scent of oils from non-pollinated plants was judged as being more intensive and more powerful. The scent originating from pollinated plants seemed to be more of a typical "hemp odor".'' and '' Hemp is known to build large amounts of new flowers as long as it does not become pollinated. Prevention of pollination leads to greater amounts of flowers and also to significant higher essential oil yields (Table 3). This strategy is also known by growers of drug Cannabis and is called the "sinsemilla" technique. Prevention of pollination in fields with a size of economical relevance is nearly impossible, but easy to carry out in a greenhouse.
The quality of oils was rated as "very good" or even "excellent", regardless if pollination took place or not.''

Yes, they didn't test the cannabinoid content of both pollinated and unpollinated. So theoretically they could still be the same... I just don't think so.
You are right pollination does lower Cannabinoid yield. Not by 50% like with the terpenes, but maybe half that.

@karl.uk: there's a company in Ireland that also grows Finola and markets the juice. So I think your good with growing Finola in your place http://healing-with-hemp.com/hempjuice.php
Sinsimilla Finola females excl, being grown on my yard at lat 65 Finland.
The tallest females here are now standing beyond 2 mtr tall.
To remove the males is indeed a painstaking process that'll take about one month all together, but it was significantly more easy to do on the other side of the plot where the plants have been sown in more thinly.
There is always a risk that some retarded seeds will still pop up, and has it got my up most priority to keep soil surface free from obscuring weeds for inspection.
(In the upper right corner of the first pic, and the third and last pic as well, there's also 'broad bean' to notice. We had a rat infestation this year that killed off many of the beans, but luckily they did not seem to care about the hemp at all. The beans are not much to see on the pictures in here, but on places where rats did not bother digging em up, the hemp seems taking a huge advantage of their presence)

This picture was made on 11-7 and it'll show off the side of the plot that was being sown in more thinly >
