Tony's silver thiosulfate notes
- Thread starter Tonygreen
- Start date
“ And
5.9566 grams sodium thiosulfate pentahydrate in 240 ml water
Or
3.7946 grams sodium thio anhydrous in 240 ml water”
Did u use the sodium thio anhydrous or sodium thiosulfate pentahydrate in your recipe?
And where did u source them? Thought i read about people getting flagged ordering the silver and sodium from same place...

Dont start until day 7. They still get to stretch in my recipe.
I finally spotted male parts forming on the plant I sprayed. I will have to look over my notes. It took longer than I expected but we had a brutal cold spell that lasted a couple weeks. It landed right in the middle of this experiment. Ended up doing a 4th spray after the cold spell. I think it's happening...

Yes. Extremely viable, With my over pollination and extra work it was my best seed production last year even beating males. I am reversing again shortly and will repeat day 7, 14 and 21 sprays.
The hard part is letting go. haha. If you keep spraying theyll never mature and fall off. You gotta just stop on that last one lol.

From F# forum. A thread from many years ago. Dozens of people and tests. 547 thousand views in over 10 years. From STS through AgNO3 itself, techniques combining Ga3 with the above-mentioned as well as cobalt chloride.

Another Polish forum. the method and concentrations used are a copy of the procedure worked out on F #. Forum founded by F # refugees.
https://www.growlike.pro/forum/nasie...art=0&start=70
The procedure popular in the forum # is basically a copy of the technique used in the cultivation of parthenocarpic female cucumbers. From a series of tests it appears that cannabis behaves more or less similar to. About 10 years ago. Rather higher doses compared to previously available procedures. At that time, ready-made STS solutions were available in Poland. Usually copies of routines from a former overgrow.
What is most interesting about it is the use of combined procedures [silver + Ga3 eg] and cobalt chloride.
CoCl[SUB]2[/SUB]Cobalt(II) chloride => the procedure used is in the thread mentioned at the beginning.
https://en.wikipedia.org/wiki/Cobalt(II)_chloride
Maybe interesting, maybe not. A lot of people took part in it. Collected experience, in some cases it was not very clear why something went wrong. In the end, perhaps the conclusion was that - rather genetically conditioned infertility and the addition of Ga3 to silver does not improve fertility, probably.
also other ethylene inhibitors have been tested. Unfortunately, nothing came of this experience. Those that are described in the scientific literature, in any case, work in doses relatively similar to those for silver. Other more exotic compounds, such as nickel compounds, did not work. The reports on aspirin have not been verified.
The first version of the F # method. => Gru 18, 2010
We need to make two solutions, solution A and solution B.
Solution A: Dissolve 1.7 g of AgNO3 in 100 ml of distilled / deionized water.
Solution B: Dissolve 6.32 g of anhydrous sodium thiosulfate in 400 ml of water - it does not have to be distilled. (If you have water thiosulfate (Na2S2O3-5H2O), that's ok too, just add 9.92g instead of 6.32g)
Preparation of STS solution: To obtain a 0.02m STS solution, we mix the solutions in a 1: 4 volume ratio, i.e. we give 1 part of solution A and 4 parts of solution B. In the STS obtained in this way, all the silver is in the anionic form. Always add slowly 1 part of solution A to 4 volumes of solution B with gentle agitation. Syringes can be used for drawing up solutions - one per solution. Do not swap.
Dilutions. Tap water can be used for dilution. Sodium thiosulfate dissolves silver chloride / bromide etc. Therefore, the chlorides present in the tap water do not interfere with anything. The problem will only arise when you salt the water.
For single spraying in the early growth stage. First signs of flowering and / or time to switch to 12/12:
1: 2 -> 0.006 m => 6mM
1: 3 -> 0.005 m compromise. =>5mM
1: 4 -> 0.004 m => 4mM
Range of watery concentrations needed for repeated spraying 2 or even 3 times at intervals of 5-10 days.
1: 7 -> 0.0025 m =>2,5 mM
1: 8 -> 0.0022 m => 2,2 mM
1: 9 -> 0.0020 m => 2,0 mM
Very similar method to the procedure used on F #. Essentially the same range of concentrations when replicated several times. To improve absorption, a dishwashing liquid was recommended instead of the tween usually used in such cases. The minimum dose, such that it does not foam.
Here are the effects of using a copy of the "mohan ram" procedure. Ear cleaning stick instead of a micropipette. Silver nitrate 500 mg/l alone with the addition of a surfactant [dishwashing liquid] a single drop squeezed from an ear stick, a few repetitions. Practically local action, as long as nothing drops off the stem. In this form, silver moves much slower in plant tissues, while the form of a thiosulphate complex moves very quickly and you can, for example, simply lubricate the stems several times with a very concentrated solution, it spreads quickly.
The method below was used for the partial sex change of plants intended to obtain the S line from selfing. 5 cycles _ with more or less expected results. Useful when you want to produce a small amount of male flowers on a single top. It's also possible with STS or even CS _ in the forum people did it too. At CS, a lot of repetitions and rather local spraying with a micro perfume sprayer.
Cucumbers, the results that people obtained in the forum were similar, as well as the toxicity of silver nitrate for plants. At the same doses of silver in the form of a thiosulphate complex, it does not have the strong side effects characteristic of AgNO 3. It can be said that the totality of the so-called experiments was based on cucumber techniques.
Pollen fertility. Some without a problem, some not at all. Exactly as described in the article you posted.
https://journals.ashs.org/hortsci/vi...ticle-p547.xml
It was suspected that Ga3 might [by analogy] help in situations where pollen is sterile. This compound has been used to restore fertility in some self-incompatible plants. For the reproduction of the line of some of the self-fertile varieties [I think onion _ intended for easy creation of F1 hybrids ?? I do not remember a decade has passed since the time when people were looking for a way around emerging problems]
Silver oxide. Instead of CS which is actually something like a mixture containing some silver ions possibly coming from the silver oxide that is being formed. Darker brownish versions may contain a colloidal suspension of this compound. It probably also contains silver carbonate, CO2 from the air.
https://forum.haszysz.com/threads/tl...nizacja.75433/
The electrolytically obtained silver oxide from any alloy, it don"t need not be particularly pure. It dissolves in thiosulfate solution, the resulting solution is basically the same as ordinary STS. Application results. Sterile pollen - which is not related to how the ethylene inhibitor solution was obtained. The idea to do this popped up somewhere on F # and was implemented by someone. Similarly, copper oxide was obtained, the purpose of an addition to farms for painting flower pots.
the addition of sodium base NaOH during electrolysis causes the formation of AgOH which is unstable and falls out of the solution as silver oxide. Instead of passing the silver ions between the electrodes as was customary in the preparation of what is called in CS forums, they are removed from the solution in the form of an oxide deposit. The dried oxide can be weighed and dissolved in the thiosulfate solution. Known weight of oxide - calculated amount of thiosulphate in solution form - typically 4 moles per mole of silver. But you can also 8. Then dilute the obtained STS to a known volume and there is a similar solution to that obtained from nitrate. The silver oxide is not pure so the resulting STS may be slightly less active.
Sodium base is readily available pipe cleaner in loose form. They usually add aluminum filings to it, which needs to be separated.
The amateur production of feminized seeds was very popular on the forum #. Probably almost all available methods were tested. There are also data on efficacy-enhancing additives to STS, some growth retardants. This is strange as these substances act in opposition to gibberellins, which are also used to sex-change female cannabis.
Lots of reports, talk and photos. Forum section dedicated to this. Besides, in many photo reports there was a lot of it outside the designated place.

Very interesting post so thank you very much for sharing.
I've had some thoughts on intersex rates in progeny as related to a particular method. I know in particular several big breeders who have a fondness for the ga3 or others that you water in once and done. Interestingly 2 in particular i can think of are putting out massive numbers of feminized seed using root drench ga3 or similar due to the ease of the reversal and it seems they have a large number of intersex plants. No doubt we will see much more research done in the coming years. Maybe some surprises too ha.
