Feminisierte Samen selber produzieren

MöglichkeitNr.2 Sibernitrat
Dazu benötigen wir folgendes:

1. Silbernitrat
2. destiliertes Wasser
3. eine weibliche Pflanze
4. einen Wollfaden o.ä.als Markierung

Los geht’s
Wir mischen 0,1 Gramm Silbernitrat mit 0,5 l destiliertem Wasser und besprühen damit unseren markierten Trieb von unserer Patientin und schicken sie in die Blüte.
Die Blätter werden sich die erste Zeit etwas hängen lassen dann erholen sie sich wieder. Unser Trieb wird dann männliche Blüten ausbilden, jedoch hat der Pollen nur weibliche X Chromosome wodurch nach der Bestäubung garantiert weibliche Samen entstehen.

Auch bei dieser Methode wird bei unserer Patientin wieder eine chemische Vergiftung zugefügt weshalb sie weder zum rauchen noch zum Verzehr geeignet ist

Habe hier noch ein Video gefunden in dem sich einer die Silberlösung selber herstellt. Ist ganz gut erklärt finde ich. Diesmal auf deutsch.

Habe mal einen Versuch mit Kollodialem Silberwasser gestartet

Mein lieber @herr_gruen ,

Zum einen, erstmal Hut ab für deinen Mut einfach mal sowas zu machen. Das trigger ja wahnsinnig den “Dr. Weedenstein” in mir.
… Elektrizität… Gefährliche Chemische verbindung… Pflanzen… “it’s Allive!!!”

Ich bin echt so gespannt ob es auch bis zum Schluß klappt. Ich drück dir auf jeden Fall alle .

Ich folge dem Thema jetzt mal genauer.

Grow on

The stigmas have fallen off and the ovaries are swelling. I will wait another 3 weeks and then carefully open a node to see how far the seeds have matured. I don’t want to harvest too early and thus ruin everything. It continues to receive fertilizer according to schedule and sun. After 10 hours of freedom, the lady goes back into her box in dark confinement.

Today I removed the two male shoots. Since a seed needs about 4 weeks to ripen and it’s nearing the end, they are no longer needed.

At the base of the stem, there were also purely female flowers, so I immediately checked if there were really seeds and

found them right away. However, these were not yet ripe. Now I will let them stand for about 3 more weeks and then check again randomly before I harvest the seeds.

@herr_gruen THAT’S ABSOLUTELY AMAZING!!!

So that means if I take a female from my oldschool regular Ketama strain and grow it out with the lady, I’ll have feminized Ketama seeds? Or will there still be Y chromosomes present since it’s a regular strain?

@Growstarter40 If you take a female plant and treat one of its shoots to self-pollinate it, you will get purely feminized seeds because the Y chromosome is not present in its genetics, meaning they will have two X chromosomes. This works equally well for photoperiod and autoflower plants. You should start the treatment before the flowering phase begins. Mark the shoot you want to treat and make sure the other shoots don’t get any of it. This is how breeders do it. The plant must not be smoked or consumed as it will be toxic due to the treatment. If you do this with two plants, you only treat one of them and use it to pollinate the other, in which case you dispose of the mutated male plant after pollination and can smoke the pollinated female. Keep in mind that seed ripening can take about 4 weeks; I would wait a bit longer just to be safe and possibly take a sample before harvest to check if the seeds are ripe.

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 and since I now have a few old-school strains, I’ll try something tasty

Hey there @herr_gruen ,

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

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

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

Cut off the shoots and laid them on a newspaper to dry

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

It 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 @herr_gruen !!

… So MEGA “my friend”!!!

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 , With this, you’ve made yourself completely independent from all breeders!
You’re creating your own genetics!

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

I’d immediately want to grow something from that!

Please continue this topic!

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

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

Grow on

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!?)

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!

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 ,

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

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. )

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

Grow on
