The Israeli professor who invented rare cannabis strains

How to make white cannabis ou purple indeed black, how to determine in advance the percentage of active ingredients, which cannabinoid might make you hallucinate and is there a chemical difference between "Indica" and "sativa", these answers and more in an interview with the Israeli professor who produces very special cannabis strains. An interview with Israel Cannabis magazine.

How does Monsieur want his weed? violet? white? lemon scent? diesel? with compressed flowers? hard? sweet? Questions like this are still a dream, but these days that dream is probably closer than ever to come true. The specialization in cultivating cannabis strains in recent years, particularly in Israel, has led to success in producing rare strains that in fact have never existed before.

During the development of the plant, external signals are not everything. It turns out that the amounts of active ingredients, cannabinoids, terpenes and flavonoids, can also be determined in advance!

A business that needs a 22% THC strain with a mango flavor? It's possible. Want a clear-tasting, non-metallic purple strain that contains 10% of the mysterious parent cannabinoid CBG? It's possible. You want a strain containing 5% of THCV, the slimming cannabinoid and two particular types of terpenes? It is also possible.

This innovation is not only good for consumers interested in scents, effects and colors but also in the field of medicine. Once the researchers discover "thesurrounding effectOf a strain, it can be produced exactly under its cannabinoid and terpene composition and thus treat a health problem.

Professor Moshe Fleischman (64), an Israeli geneticist who worked at the Volcanic Institute, the largest agricultural research institute in Israel, a cannabis researcher for about 4 years, insists he can do it today. hui. In a conversation he explains how it came about and where he is going with it, what special strains will be on the market soon, what they will contain and also some advice like for example - why not buy such cannabis seeds if you want the herbaceous plant.

What exactly are you looking for in your project, what exactly is the innovation and what is the genetic origin of the strains you have developed?

It can be said that after 2000 years of exile, there is an orderly improvement of cannabis. This orderly improvement means that the imported varieties are taken as seeds from all over the world, with broad and rare cannabinoid compositions, they first undergo hybridization with different genetics, then hybridizations on hybridizations and so on. Each hybrid gives a difference in flower structure, color, size, cannabinoid composition, disease resistance and more. Everyone prioritizes their goals, I call them “filters” and picks the best each time. With them, depending on the filter you set, you produce the next cycle, so there is no connection between this and the source varieties it comes from.

What about the flow to high THC? That everyone wants strains with as much THC as possible, and why don't you have any?

It is really an area in which I must invest myself. When I first started I said I didn't intend to get better about THC, but in the end that's what the market wants. So we have such strains coming to the market right now, for example “Inspire” from “cannasure”, with around 18% THC and we hope to reach over 20% soon. As far as I know, the people of the Woodstock era supposedly became addicted to cannabis with 3% THC, and the demand is increasing. I thought 17% or 18% is enough and we should focus our efforts on other characteristics, but today everyone wants a higher and higher "high". If we are talking about medical cannabis, we are also looking for other cannabinoids, for example cannabigerol CBG, which is the new CBD.

Is there a limit to the percentage of active ingredient that can be achieved in cannabis in general?

Good question ! In my opinion, the cannabis plant on the cannabinoid topic has a limit, an upper limit, a total amount, that if you hit a total of about 30% cannabinoids, that's a significant percentage and probably it will be difficult to do better.

Protrusion is one of the characteristics that can be determined in advance, according to Professor Fleischman

So the innovation is that you know how to produce cannabis strains on demand?

As I said, I think this is the first time that such an improvement program has been put in place, to create unique genetics, in cannabis.

Other companies will say they do, why do you say what you are doing is complicated?

Because orderly selection means that you are selecting varieties after 4-8 generations of hybrid combinations. Plus, you know the heredity of cannabis traits, you know how to tell if it is the mother of other cuttings, if we will get a huge amount of THC out of it, or if it will cripple it. I understand genetics, heredity. Anyone can sow and pray of course, it is a beautiful process, but it is not an improvement. The varieties that we started with are varieties that people have sown and found appropriate, but from there to do an orderly improvement process, as is the case with tomatoes, is a different register, it is a science in itself. With all due respect to the companies that bring in and grow seeds from different sources, this is just the start. From there, making the combinations, continuing up to the 5th generation and beyond, in goal oriented combinations, is already an improvement.

What do you think is important as a characteristic of cannabis in terms of properties?

The smell. All our varieties are scented in a crazy range. We have no limits on odors and it is very important that users recognize the strain through the smell and there is an amazing variety of smells that we introduce through hybrids, based on terpenes of course. , one of the companies asked for the smell of skunk ("skunk"), I know how to do it, to find out if such a smell comes out of the lemon where it comes from elsewhere, or even from these predators who are also part of entourage effect, according to experts.

What interesting cannabinoids are there in the new varieties and how do they affect them? What's the big news?

We all got V, THCV, CBDV ect .. and so on, in relatively high percentages. I am not addressing the medical issue of the cannabinoid effect but it is the main point, we have to look at it strategically. Israel has been a powerhouse in the development and understanding of cannabinoids from the lineage of P. Meshoulam but was not in the field of strain creation. They would buy seeds and bring them from Holland. Now we have become a bespoke genetics creator, that's our uniqueness, because what we have today, no one in the world has.

If we put medical aside for a moment, genetically, odors, sizes, percentages of active ingredients, what do you think is the best success?

The most extraordinary success lies in the compositions and recipes of cannabinoids. Today I know how to put them in symbiosis to produce cannabinoid compositions that are not available in the world. To produce a flower, there are other people who know how to do like me but the compositions of cannabinoids and terpenes and know how to compose with a little of this a little of that so that they end up reducing or increasing this or such receptor is the medical aspect and that is our real singularity.

How does the relationship with researchers work?

There are two modes of action, either we do something specific asking the 'doctors' what we can do with it or the doctors come to us and say' listen, we found that there has an advantage in this or that composition, do things for us ”. At the end of the day, if you look at the cannabis plant, what we're selling is chemistry, and we're creating targeted chemistry.


In conclusion, you say that you can go down where to increase not only a resolution of THC and CBD, but also that you know how to produce a flower that will also contain X percent THCV, a specific amount of "myrcene" terpenes, stuff like that? And so in fact, you are able to "build" an entire recipe and it can be perfectly tailored to whatever the researchers want. People are passionate about shapes and colors. If it is a round or elongated or pear-shaped flower, one with red, purple, white hairs, a purple flower, etc.

We are already able to respond to them, it suffices to prioritize the objectives. Now if you want high THC then there will be high THC. I repeat, we create chemistry, so we end up producing chemical compositions that correspond to the medical aspects. Of course, we also need high productivity, far-reaching medical effects, at the end of the day it's a joint work between us and the doctors. It is a plant that is produced for medical purposes. We can of course also see the aspect of leisure, but in this aspect the range of psychoactive substances is very limited. In terms of remission, entourage effect, the range of ingredients is much wider.

His breeding and hybridization project is carried out by Professor Fleischman in collaboration with the cannabis farm “Bar Lev Agricultural Crops” in Moshav Kfar Hess. The results of the first cycle of cultivation from the fruits of its development can be tasted by consumers as part of the "Select" series of the company "Cannasure", which includes the varieties "Karma", "Spirit", "Inspire "And" Grace ".
