Feminisierte Samen selber produzieren

This is great info, I discussed with many breeders at Mary Jane, but no one wanted to go into detail about how the two females cross with each other :grin: and since I now have a few old-school strains, I’ll try something tasty :saluting_face:

Hey there @herr_gruen :victory_hand::smiling_face_with_sunglasses:,

I just checked my notes on the topic again… It says… “the ripeness of the seeds determines the flowering period of the chosen plant.”… For me, that means if you’ve chosen Strain XY, you only need to reach the complete maturity of the flowers… (8-10 flowering weeks). And, ideally, as can also be read in other forums, add another week… Your lady should slowly be ready by herself by now… But that’s all just “hearsay” from the web. There’s hardly any decent, illustrated documentation for it. What you’re doing with your experiences and the pictures you’re sharing with the community on

I will also start a second round after my vacation in a few weeks and cross two strains with each other. I’ll use a Fat Bastard and a Bubble Gum Sherb for that. Then, during that run, I will also create a Growlog for it and document everything in a bit more detail.

Experiment No. 1 is a Gorilla Sherbet
Screenshot_20250116-084503_Chrome
In the tent today is F69 W10; I had sent the experiment into flower a few days prior. Since it’s the first attempt, there were a few starting difficulties. I first treated one shoot with Gibberellic acid, and when the desired signs weren’t visible, I tested colloidal silver water on the second shoot. Because of this, I was approximately in the third week of flowering when the first male flowers appeared. In hindsight, both methods had worked, with the silver water showing the desired signs faster. Regarding the cost factor, I also prefer the silver water as the diodes last forever; my great-grandchildren can still use them. The only things I need to buy again are the 9-volt block battery and distilled water. But I digress; the plan is to harvest her when her counterpart in the tent has reached the desired maturity, which, according to the breeder, would be around next Sunday, then at least the 11 weeks would be complete.

Use a small switching power supply or a small 9V power supply. I have tons of such parts lying around here, from old phones, routers, etc. I always keep all the plug-in power supplies when I dispose of the devices.

Hi @Dbe, I also did some research last night, and regarding the gibberellic acid method, it’s said to be rather outdated because it produces seeds that are not very resistant. Colloidal silver solution 30ppm is available at ama… and the procedure is the same.
The completely natural variant is called Rodelization, where the flowers are sent into overripeness; they want to reproduce, so they first form large nose-like buds to catch pollen, and as a very last resort, hermaphroditism, producing pollen sacs with female pollen from the buds.

The variant with colloidal silver is probably the breeders’ choice as it is reliable and productive…but yes, it all takes its time, one way or another…but remember that you can now cross your favorite strains yourself and develop a new feminized strain :melting_face::star_struck::squinting_face_with_tongue::zany_face:

So, the time had come, I finished the experiment today

20250808_175245Cut off the shoots and laid them on a newspaper to dry

20250808_175738And since I had to wait so long, I also directly plucked the flowers from the branches and checked what was inside

20250808_181906It was a sticky but very good smelling affair.

And TADAAA, some immediately stuck to my resinous fingers. Now I will wait until the flowers are dry and then take out the rest of the seeds.

All in all, a successful experiment. And expandable.

Meanwhile, in the tent, I treated a few of the lower popcorn buds from my two other strains with Gorilla Sherbet pollen, using a brush to specifically pollinate only the flowers that would have been too small for smoking anyway and also received too little light. This way I created a strain from a Fat Bastard/Gorilla Sherbet and a strain from a Bubble Gum Sherb/Gorilla Sherbet. Both were successful. The Bubble Gum is already curing and 28 seeds came out of the two mini buds. I briefly checked the Fat Bastard when I hung it on the clothesline and immediately had one on my finger; the rest will come out during trimming.

Next month I finally have vacation and then I’ll start the next round, where the Fat Bastard will be propagated and I’ll cross it with the Bubble Gum Sherb. This will result in my desired strain, the Black Forest Queen. This time with a grow log. And since I will only be treating the Fat Bastard, I can still enjoy the Bubble Gum Sherb when it is harvested.

Have fun recreating it

Wow :exploding_head: @herr_gruen !!

:smiling_face_with_sunglasses::ok_hand::cloud: So MEGA “my friend”!!! :+1::+1:

I can barely contain myself with something like this. I already have an itch in my fingers to try something like this myself!!

No joke, man :wink:, With this, you’ve made yourself completely independent from all breeders! :+1:
You’re creating your own genetics! :+1::+1:

If the germination rate is good now… :thinking:… Although it almost doesn’t matter. You have enough to throw into the soil. :grin:

I’d immediately want to grow something from that! :seedling:

Please continue this topic! :folded_hands::folded_hands:

I’m curious what other strains you’ll come up with.

P.S.: How long does the treated water last?

Colloidal silver water should be stored in a brown glass bottle in a cool, dark place. But it doesn’t matter if you make it yourself. The diodes last a lifetime. The only things you need to repurchase are the battery and distilled water. From that perspective, I prepare it as I need it and am always on the safe side. Furthermore, plants grown from seeds are stronger and not as susceptible as cuttings. You also save yourself the waiting and hoping that the cutting will sprout roots. Since the seeds don’t cost anything anymore, it doesn’t cost as much money if you constantly germinate new ones.

As I said, after my vacation, I will start another run with a grow log and post it here. The topic still has potential for expansion.

Aahhh… (RQS!?) :wink::+1:

I had read the article years ago and always thought about it. Whether it works and is really that “simple”. Your proof now triggers me 3 times more.
I’ve already saved an online shopping list. As soon as I’m liquid enough, I’ll try that too! :smiling_face_with_sunglasses::victory_hand:

I read it in Ed Rosenthal’s book (Marijuana Grower’s Handbook) and then did some more research. I got it for my birthday last year, and afterwards, I immediately started thinking about the next seeds/strains, with the idea of trying it out and creating something of my own. When I read that, it was clear to me, “I have to try that,” and what can I say, the beginning really made me doubt. I tried back and forth until finally, there were signs of male flowers, but then it went as planned. Unfortunately, there are a few seeds that weren’t ripe, but most of them finished. However, I also had initial difficulties until halfway through the flowering period. Next time I’ll be smarter and start treating during the vegetative phase and not just when I force them into flowering. It works with photos as with autos, although with autos, you should probably start treating even earlier.

Hi @herr_gruen :smiling_face_with_sunglasses::victory_hand:,

Just quickly asking,
What did you have to try to get it to work? :thinking:

And, an exact number is irrelevant now, but roughly, how many good ones did you get out of it?
(you can also PM me if you like. :wink::smiling_face_with_sunglasses::victory_hand:)

I looked on YouTube for this… :eyes:
You can’t find anything complete on it. Or did I miss something? :ok_hand::cloud::cloud:

20250810_150215 After three days on the windowsill in the sun, I could now crush the blossoms between my fingers. Afterwards, I sieved out the fine, unusable material and then picked out the seeds. It looks like I should have waited two more weeks until harvest. There were finished seeds in there, but also many that were not yet fully ripe. A few looked almost ready, so I playfully put them on a damp paper towel, just to know for sure. I stored the ripe ones in a small brown glass vial until they are used. All in all, despite all the initial difficulties, I now have almost 100 good seeds for further cultivation, and that for free. If the ones in the paper towel germinate, the ones I’m not sure if they’re really ripe, I’ll know that next time I don’t have to be quite so picky when sorting. They were as brown as the others, but the dark spots were sometimes missing or only faintly visible. I will report back whether these also germinate.

The gold panning pan fits the theme very well :slight_smile:
I’m curious if it will pay off :victory_hand:t3:

Ripeness is easy to determine by gently pressing it between your thumb and forefinger. If they are unripe, the bean bursts; if they are ripe, it does not burst. Important: only press very gently, with care.

Last night, I placed 5 of the seeds that I thought weren’t quite ripe between some paper towels and put the whole thing in a small clay pot with a lid. Then I added some lukewarm water. This morning, my wife took a look and…

20250811_133314 Germination rate after just over 12 hours at 100%

On two of them, you can see the very delicate tip of the taproot. All in all, a complete success.

Good evening @herr_gruen :smiling_face_with_sunglasses::victory_hand:,

I need to ask something again at this late hour :sleeping_face:. :thinking:

Do you actually always only have to treat a part of the plants? Or would it be possible to only extract pollen from a plant?

My thought on this is:

Mind you :index_pointing_up:,
I know you did this for the first time too. This is more of a “What’s your opinion” question.

You only extract pollen. Which you store nicely dark and dry… How long does it last? :thinking:
First, let’s continue… So you save it, if possible, and then only pollinate ladies that have good genetics. In the flowering phase… Nicely in the lower area. On mini buds that you hardly smoke anyway, and then finally harvest both. Weed and seeds… Is this total humbug or would it be theoretically and practically feasible? :thinking::thinking:

In this sense

I had extensively researched the topic beforehand to gain some knowledge. And yes, of course, pollen can also be stored. However, after collecting it, one should first dry it. In the refrigerator, it should be storable for a month, and if well-packaged, it can be frozen for up to a year. It is also possible to induce a complete female plant to mutate; for this, it is completely sprayed over several days. The principle remains the same.

The thing with the popcorn buds in the tent is also feasible; I just did that too. I shook the pollen into a small dish and then went over a few of the lower popcorn buds in the tent with a fine paintbrush. The pollen was from the Gorilla Sherbet. With it, I then pollinated the Bubble Gum Sherb once and the Fat Bastard once. Both times successfully. From the Bubble Gum Sherb, I harvested almost 40 seeds, and from the Fat Bastard, only one so far, as it is still hanging on the drying rack. I think I can trim it this weekend and harvest the remaining seeds then.

So, with that one mutated Gorilla Sherbet, I have now produced three types of seeds. Once by self-pollination (to preserve the strain), once by pollinating the Fat Bastard (new strain), and once by pollinating the Bubble Gum Sherb (also a new strain). Next, using this method, I will propagate the Fat Bastard and pollinate the Bubble Gum Sherb with it, which will again result in a new strain. And finally, I will start a run with the Bubble Gum Sherb to keep this strain in my collection. Then I will have 6 strains, three of which are only available in my private collection.

Your approach of selecting the best and strongest plants for this is also spot on. Breeders normally plant around 50 plants for propagation and then select them based on growth, color, smell… to ultimately have the greatest possible genetic potential in the lineage. Normally, this process is repeated multiple times to get a strain as stable as possible. Unfortunately, I couldn’t afford this luxury with my resources; for that, I would need a laboratory. I also only have a 60x60x160 cm tent. But plenty of ambition.

Arrived yesterday and the cuttings are ready for flowering… I’m really keen to grow my own strains… Ketama and Skunk 1 will probably be the first! 17557955987191004697977542694628

Hey :waving_hand: @herr_gruen

First of all, thank you very much for the detailed description, I really wanted to test that too. I also have Ed Rosenthal’s book here, great book.

I have a question. It’s clear that you keep the ‘treated’ plants separate from the other plants. But what about several ‘treated’ plants of different strains? So let’s say you want to test this with several strains at the same time. Would these then also have to stand individually so that the strains don’t mix, or can you have them all in one tent? :thinking:

Kind regards
