how does this not have MORE LIKES?! i have not seen very many, if not any feminized seed information on KZbin that mentions the silver method. also your explanation of the genetic factors, is so well done, clearly excecated and easy to understand! thank you very much for this information! 😍💚 i think the method you've shown here is FAR superior to what ive been doing for my whole life, both in its simplicity\easiness to follow, and the fact that it is reliable and measurable unlike the way i've been doin it!, thank you so much for bringing up up-to-date!! XD [warning: THE FOLLOWING SHOULD ONLY BE ATTEMPTED OR CONDUCTED BY A PROFESSIONALLY MINDED ADULT, IN A SAFE CLEAN ENVIROMENT, USING THE PROPER PPE AND PROCEDURES] i always used colloidal silver (sp?) which i was taught to make by an older grower, by making an anode and cathode out of pure silver solder wire, and attaching each end of it to a small voltage\ milliamp DC wall transformer (plugged into a GFI\fused power source for safety) then i would put those two thin rods into a glass or jar of distilled water, and leave it on overnight, and after a while you could actually see the silver forming strange tiny dots and orbs FLOATING in the water itself! like it somehow stayed in solution ionically or something? anyway this stuff was really dangerous to get on bare skin, so if anyone follows the above directions be very careful and use proper protective gear\gloves\mask\goggles\lab coat etc. a small ratio of this to regular watering\feeding times would quite quickly force my females to produce male flowers as well. (or males to produce female flowers also, making male-inized seeds) once done, the plant is cooked however, like i had to baby it along to completion (maybe i was using too concentrated of silver-water, oops!!) been a very long time since i used that method. i will definitely be giving this method a try next time i go for a batch of fem seeds!

How long do the leave the galvanic cell running?

[@bonesdoes6142]

I was able to produce feminized seeds by stressing a female plant starting around 2-3 weeks into flowering. I let her pot dry out a few times,did some pretty extreme temperature swings,and then lowered the light until I caused some minor light burn. She threw out some pollen sacks and I got some female seeds out of a couple healthy females I used the pollen on. So far my results have all been females,about 50-60 seeds in. Not as scientific,but it worked😅 Great video!

[@DeBaccoUniversity]

Glad it worked for you, but this would not be a reliable technique to depend on and there is also the plant stress to consider.

[@MarkSwanger-sz8bf]

Would the seeds that come from a purposely stressed hermie female produce hermie prone seeds?

[@HamperzTV]

@@KushByTheBush From what I've been reading, the seeds produced from the plant will only contain fem dna because the mom (regardless of being hermied) is still fem.

[@TheObserver3]

​@@KushByTheBush Yes if the new plants are stressed in the same ways they are likely to herm' but if you don't stress them you can get some amazing bud' I've done this myself and as long as I don't stress them they stay female.

[@MrBradshawbenjamin]

This is great, and thank you! I love the info, but the typos on the chemical preparation page bother me a little bit, although if people follow it as written they'll get the right result and they'll never think about stoichiometry. Ignoring the hydration - since you got the pentahydrate part right - sodium thiosulfate is Na2S2O3, not NaS2O3. Silver thiosulfate is Ag2S2O3, not Ag(S2O3)2. Also, they mentioned how methylcyclopropene might work, and if people don't know, that's the gas that they use in the supermarket to keep bananas from ripening.

[@MrBradshawbenjamin]

So I was kinda wrong here. The sodium thiosulfate was wrong, but the "silver thiosulfate" was close to right in the video although it's more complex than that. It's not Ag(S2O3)2, but the [Ag(S2O3)2]-3 anion, so the chemical species would be more like trisodium silver dithiosulfate, although the silver dithiosulate is just the predominant ion in solution, and other complexes are present as well as sodium nitrate.

[@MrBradshawbenjamin]

@@DeBaccoUniversity I feel kinda dumb for typing that now, but on the other hand I'm glad I did since it made me look into it deeper. Thanks for the works cited!

[@nuclearstarr]

I have a couple questions. In the video, you used rooted cuttings; in the case of using plants started from seed, when would you begin the STS treatment? Assuming that you have several other of the same feminized plants growing next to the plant that is treated, should the also be sprayed or would the pollen from the treated plant be enough to fertilize them, too? Would it be more effective to collect the pollen and use a Q-tip to pollinate the other plants, rather than treat them? You say that you did three applications 7 days apart, with the first on April 30, but you say you did the second application on May 14? Wouldn't that have been the third application, with the second being on May 7? You say that you switched to the 8 hour light cycle on April 30 and on May 14; if you began on April 30, how. could you begin again on May 14? Was there more than one set of test plants? I have seen some videos that recommend only spraying part of the plant, perhaps a few leaves or one branch. Any thoughts on this? Are there some varieties that do better than others with feminzation? Indica versus sativa? thanks

[@DeBaccoUniversity]

Answers to all your questions... 1. Plants were ≈6 inches high with two shoots when foliar sprays of STS were initiated 2. If other plants are female, no pollen would be produced if untreated. 3. Treatment is needed to generate the pollen. 4. Plants were sprayed to runoff (about 20 mL/plant) on three occasions, 7 d apart, beginning on 30 Apr. 2018 for the first replication and on 14 May 2018 for the second replication of this study. 5. On 30 Apr. and 14 May, plants began receiving short-day conditions of ≈8 h using a blackout curtain to initiate the flowering stage. 6. Full plant sprays in this study. 7. Should not be a difference.

[@nuclearstarr]

@@DeBaccoUniversity Thank you. A plant grown from seed may be taller than 6 inches before it produces sex organs; do you treat plants grown from seed as soon as they display female sex characteristics, or do you allow them to grow buds before treating them? What i was trying to ask for #2 was if the amount of pollen produced by one treated female would act to fertilize surrounding females enough to produce a large quantity of seeds, or would it be better to use the pollen from the one treated female to hand pollenate the other females? I don't understand your answer for #5; if you begin the blackout curtain on April 30, how can you begin it again on May 14 unless you stop sometime in between?

I have another question for you. Once a female clone is reversed with sts and produces pollen. Can that pollen be used to breed with other female clones of other strains to produce feminized seeds of different strains? Is this process ok? Or should breeding be done with a real male and female plant then reversed to produce feminized seeds?

Basically, yes as the feminized pollen only has the X chromosome so pollinating other female flowers will result in feminized seeds.

Once a female is reversed with sts to produce male pollen sacs. What type of nutrients should the plant receive to help mature the pollen? Bloom nutrients?

Question. If we apply this method to cuttings from the same mother will the seeds essentially produce the genetically identical plants to the cutting? When breeding I believe the offspring will be a random 50/50 mix from both parents but if both parents have an identical genetic code….my thinking is when you find a good keeper I’m always worried there’s going to be a disaster at some point in the future and I’m going to lose her…would be great to have a jar of seeds that I know will grow the same plant at a later date.

[@seventy18]

Question- if 1 or 2% of the feminized XX seeds end up being male plants, are they really just hermaphrodites showing more male characteristics or more male flower. So if that's the case, these hermaphrodite plants would be producing XX pollin, and it may be beneficial to keep these herms. For future fertilization for XX seeds??? Mathematically these herms wouldn't ever have xy???

[@DeBaccoUniversity]

In the best case scenario plants would still set seeds which will reduce cannabinoids and also "ruin" the visual aspect of the flower and increase labor to clear out the seeds. So, this is part of the reason why all pollen producing plants should be removed.

[@michaelcarey9359]

I think the 1 or 2% "disclaimer" is because while these plants are being induced to make male flowers, there's also the possibility that the plant might make another male flower or a few, as is sometimes seen in the best of grows, which could throw things off a bit. But if your female plant might herm anyways, that means it has the genes of monoecious cannabis in it, so the resulting seeds from this method will still pass along those genetics. You need PURE females, free of intersex genes to do this perfect.

@@SpruceSculptures its such a small amount it seems weight is the only accurate measurement, just like baking. Id suggest if serious to make this buy a decent scale for 15 bucks. We made colloidal silver using batteries and bought silver sticks. Seems a bit easier. Less math.

[@DeBaccoUniversity]

You can end up with hermaphrodite cannabis plants. Moreover, the pollen produced in the pollen sacs of hermaphrodite plants are not as potent as the pollen produces by male cannabis plants. www.getispire.com/what-is-rodelization/

Consider a video about why femminsed cannabis seeds are a bad idea.There is a problem with substandard quality with the Y chromosome absent.

[@DeBaccoUniversity]

Feminized seed or not, any female plant will have the Y chromosome absent. Can you expand on your concern?

[@SpruceSculptures]

This did not work for me. I tried two different cycles. If anything there were more female flowers. First round was done the way stated. Second round I sprayed the plant (drenched) daily. NO difference. Sorry to report this as I really wanted to get this plant to herm out.

[@DeBaccoUniversity]

Concentration and timing are key for success.

[@SpruceSculptures]

@@DeBaccoUniversity If concentration was wrong it was due to provided info. Like I said I tried it exactly the way described the first time, just altered how often the next. It did not work

[@jayo8621]

1st application 5 days prior to flower then once every 5 days til u see balls, may need to increase coincentration if superhard to flip but thts not a bad ting since it means ur workbg with a stable female.. hope you cloned... try again .. i use 1g silver 5 g sodium thio, each in 500 ml, then mix 50 of each +900ml of distilled water for a 1:9 sts to ho solution for final spray. reduce to 1;6 if still no results bnut usually soraying 1 time 5 days before flip to flower and then continuing works best

Open Question(s): Any thoughts on treating a female born from feminized seed? Will the pollen be viable? Will the resulting generation be perfected or retarded in some way? Thank you for your time and consideration.

[@DeBaccoUniversity]

Not sure of the question... a female plant will produce female flowers which are receptive to pollen, not producers of pollen.

[@tyrannosapienlex]

@@DeBaccoUniversity Sorry, Dr. DeBacco. If a plant grown from 'feminized' seed is treated with the silver solution, will the pollen that results from this treatment be 'normal' in comparison to the pollen created by treating a female born of 'regular' seed with the same silver solution? In essence, does a 'feminized' seed contain any genetic coding besides what is contained in a 'regular' seed? If different, are the differences detrimental to 'normal' expression? I suppose, that was my loooong-winded way of asking if it is safe to treat a female plant born of feminized seed, to reproduce its particular phenotype [if selfed] and/or pass on its own traits [if crossed]? Thank you for your patience.

@@DeBaccoUniversity I’m curious about @Geronimo’s Bones question as well. It’s hard to get a straight answer to this question.

[@telnek]

@@tyrannosapienlex A female plant is a female plant. However, the one from a regular pack, you will have different phenotypes/expressions of both parents to choose from (S1 from "Regular" seeds). On the other hand an S1, is from that feminised seed you choose and most of your seeds should be close to identical with the exceptions or runtz or weird ones that should be minimal. Less rececitive traits.

Do feminized seeds produce female seeds?

Depends on the pollen source used.

[@purple_princessx]

Hi again professor, if we spray a plant with the silver that is already making seeds after natural pollination will it make the seeds develop feminized?

[@DeBaccoUniversity]

No, it needs to be applied before the pollen is made.
