Short description of female seeds
Male flowers but no hermaphrodites!
A manipulated pure XX-plant which will genetically result in XX-pollen.
Pollination by those "males" will give 100% female seed.
Female or feminized seeds? Is there a difference?
While during the sixties and seventies a true 'breeding frenzy' took place in the agricultural world, quite some cannabis breeders took to experimenting with colchicine. Colchicine (a powerful mutagen for both man and animals) simply
stops cell duplication, while the cell core duplication continues all the same.
Result: a doubling (or even more) of the chromosome set. With plants this treatment can be advantageous, for when they survive they often show enforced properties such as, for example, a higher production of certain substances or an increased resistance to molds or disease. You can imagine that once in a while THC production went up as well (Netherweed). What also resulted were hermaphrodites.
When gender chromosomes double, the result is that male and/or female chromosomes appear manifold. What is the plant to do? Become male or female? No, they become all at once! The result is what we call 'feminized' or effeminate seed.
Maybe this went a little too fast? Probably it becomes more clear when you realize how nature normally organizes these things: genetically spoken a cannabis plant is more or less predisposed to become male or female. This is regulated by 2 chromosomes, which are, just like with humans and animals, an X or an Y chromosome. A plant with 2 X chromosomes (XX) becomes female, one with an X and an Y turns into a male. Just like people and animals a plant has it's own hormones that regulate the plants functioning, of which gender is just one.
This hormone balance is mostly genetically determined, but partly also influenced by environmental factors. When for example the roots are badly damaged, there is a big chance male flowers will form while genetically spoken the plant is still a female. This has to do with hormone balance. In this case a substance that is produced in the roots and normally slows down another hormone found in the leafs, will be produced in smaller quantities. Result: Male flowers. When you regard this phenomenon in an evolutionary sense this is quite remarkable, for when a female plant is in bad condition it requires much less energy to produce pollen than to form female flowers, which eventually will contain the energetically extremely 'expensive' seed.
Anyway, while discussing hormone balance, we get to FEMALE SEED: a female is a plant with XX or only female chromosomes.
When you have seed with only X-chromosomes, you can be certain this seed will grow out into a plant that is genetically female. But how can you get the plant to do this? As follows: a female plant (XX) is forced by hormones to produce male flowers. This is achieved by using a very low, very specific concentration of gibberellic acid. Gibberellic acid is a hormone which naturally occurs in the plant and is mostly involved with growth and flowering. When a plant thus treated produces pollen, this pollen contains only X-chromosomes (no Y-chromosome has entered the equation). When we offer this pollen to another female (also XX) plant we can be absolutely certain to get seeds which are 100% XX!
These seeds we call female seed.
Interview with Cees Hendriks (SpeesCess) (mr. XX) from Highlife spring 1999
Lately there has been a lot of fuss about 100% female seed. Quite rightly, because this could be the big change in the world of the growers. As you know,now it is possible to fill, without (illegal) cuttings, the gardens with female plants, which moreover as a seedling bring in more than the cuttings. Highlife was able to be the first to publish pictures of this miracle of technique and manipulation. But what is even more interesting: we have an interview with the improver of these plants, who will lift the veil and share with us the techniques and materials who until now where only known by a handful of people. This person is a devoted lover and has no need at all to reverse his knowledge into stone-hard currencies. He is a man with a vision and in his story is a message, as well for the improvers of seed as for every blower in Holland. Because of the discretion, we call the super freak ‘Mister XX’, what, in view of the matter is a very appropriate name.
Dear XX, could you tell us what has driven you all those years? Because it is such a complicated matter, it has cost you lots of time and you encountered a lot of set-backs.
Indeed I was already experimenting for years, before I got some results. But I am a kind of person who digs in the heels of matters that interest me, certainly when the rest of the world also has no solution for it. By all set-backs I suffered on the road, the desire to succeed is getting stronger. The only disadvantage of all those years of experimenting was, that it was nearly not smokable. Belief me, this matter is for people who want to grow their own smoke not recommendable. But luckily I got that phase behind me.
Why did you work all those years at producing female seed, and what will you do with it now you ‘cracked’ that formula?
My goal was to make of really potent XX plants minimal a natural healthy quantity of female seed. When I, after ‘eternal’ experimenting, was ready, I began to cultivate this seed, to see if it, after a while would decline. Then I discovered that the material where I work with, was also useful to bloom more fully, in a shorter period then we are used to. But, we will talk about that later, because this is not so interesting for me. Certainly not, because I will wizen up the breadgrower, who mostly use pesticides and other stuff, just for the money. Because I belief the chance is very small and because other people in this world where marketing female seed, I did not want to keep this to the persons who also where interested in these matters: in other words: I want to pass that the stuff that I use, is free of poison and work very well.
You have our complete interest, so tell your story and begin at the beginning.
To produce XX seed, you need a 100% XX plant. To determine if a plant really is pure and if this is a XX-plant, can not be too difficult. To disturb the cycle regularly, by using light to recall shockeffects, is a good method to commit hermaphrodites. It is optimal if you, while shocking, give the some more CO2. But, make sure that you give them in time trace elements. By all these strange moves they use a lot of extra, especially magnesium, I noticed. When you finally have one or more pure females, then they will be the base of the improved species. But, look out, because there are very little pure XX plants, how strange this may sound. Inattentive breeding in the past, with especially Asiatic plants, have genetically in depth produced much hermaphrodites. So, when a plant is not pure XX, the pollen can also not be pure XX. This is very frustrating, because all the work has been for nothing. But, if you have found a XX-plant, we go look further. After years of experimenting and seeking, I was three years ago able to cover the XX plant with it’s own dust. But it did not really hurry up, because the length of the cycle was very disappointing to the yield.
Most people would be very happy if they would come this far, but we understand that this was only the beginning for you.
Yes, this gave me a kick, but more like: ‘And now we really get started!’. Now I can also solve this problem. Today I can manipulate every XX plant that I choose, as you can see on the pictures.
You see a plant who is showing on three branches, three different kind of inflorescences. It is a strange and unusual sight, but very exiting to me. Because this was for me the way to good and potent female seed. But also (this appeared later) the way to a 30 to 40% more and full bloom of the ladies, and a shorter blossom-time of almost a week. With this I demonstrated the possibility of the plant to treat one ore more branches different. As you can see, I can take care of full bunches of male flowers in a XX-flower, who is producing a lot of pollen.
If one ore more full sisters of these plant are in full bloom, put this manipulated plant between them for fertilization. Now the fertilization will take place only if the plants has full blooming tops, and that will give you lots of seed. Only a plant with some big bunches of male-flowers can fertilize a big room of plants.
This was a nice story but the question stays how to get those male flowers in that plant. We have waited long enough, now we want to now what means you use. Go right ahead!
I want to tell you a lot, but not everything. There are different materials where you can manipulate with. The material I have chosen for is Gibberelic acid, that is also known as the German name GIBBERELLINSAURE. But at this moment there are five different performances of Gibberelic and there is a big chance that the producer has other compositions. The reason I have chosen for this, is because I let it tested by Dr. Alink,, a toxicologist from Wageningen. The result I got in writing n it says black on white that it is harmless for man or animal. This test is executed without questions or any opposition, what says that it is possible for everyone to test materials on harmfulness. So, in other words, we can work much harmful as we all know. And it costs: nothing!
Gibberelic acid is harmful on its own. It is strange that the material has not been added on the list of pesticides who are not allowed in nature.
But you can spray Gibberelic on the plants?
No, that would be very easy. First you have to dissolve it. To dissolve a synthetic acid as Gibberelic is a story at itself. Now I use Natriumhydroxide, a very aggressive material what is used as a purgative. Natriumhydroxide solves very easily and it is not toxicological not dangerous. To find the right proportion is the next question. Then you find out that the condition of the plant sometimes asks for a specific proportion, who deviates to far behind the comma. If you can not weigh to specific, than it is not going to work out. It is that accurate. The difference in doses are so small, that making it is more than a precise job. A pharmacist as a friend will be very useful, but he also can weigh at 0,05 grams. But especially choosing the right moment is the biggest problem.
If all these things are right, then it is just a matter of spraying, and ready we are, I mean Mr. XX is.
Yes, that is true. Surely reality is far more complicated but I lifted a big piece of the veil. I did this because I think that all blowing people in Holland are entitled to know what is happening. So, here I give a piece of my experiences in these matters. I hope that the people who are busy manipulating will test the materials they use in toxicological values. This is free of charge and the examinatiors don’t ask annoying questions. For me it is the only way to inform people in which materials you use, those which are mentioned on the package. The time that growers and improvers had to work with poisoned materials such as Colchicine, is really long gone.
