Have you tried higher STS levels like Tony Green used? .. he used much more potent STS solution than the recipe on the opening page. Tony wrote down his method few pages ago in this thread and has a thread about his STS experiments. He posted a link to it few pages ago.
I have also a very sex stable CBD plant and i was thinking i need to look into stronger STS spray to reverse her but i still haven’t tried making fem seeds with her or any other plant, but i’m having a go fairly soon.
I'm going to try this again.
I still have my stock solutions and the leftover mixed up solution from last try.
How do you all think the best way to try a stronger solution is? Add some of my silver stock solution to the already mixed? Make a whole new mixed solution?
any ideas on amounts? I feel like I'm pulled in a million directions in life and can't come up with the brain power to see the best way. thanks!!!
Hi. What can be the reason for the lack of pollen in male flowers? The plant normally began to produce men's flowers after sprinkler with silver but in flowers there is no pollen. After some time, they fall from old age without creating pollen. The STS concentration was not too high, another plant gave pollen.
I'm going to try this again.

Thanks for your help.My friend has tried over 100 reversals to different plants with success every time.
Mix a fresh batch then,
Full strength sts (no dilution) on day 1 and 15. Biggest things to watch out for mistakes imo are the version of sodium thiosulfate your using. And that the pollen donor plant needs to be started much earlier to match up pollen drop to seed bearing plants. My friends recomendation is 2 weeks early for indicas, 3 weeks for hybrids, and 4 weeks plus for long sativa.
Sodium pentahydrate needs to be mixed at a ratio of 3.9g to .5g silver nitrate. While sodium anhydrous needs a ratio of 2.5g to .5g silver nitrate. I mixed up these and used the pentahydrate at lower concentration and only got one plant to fully reverse out of 16.
And for the second mishap, I can see if I didnt know about the delayed pollen drop, that I may think the process didnt work. When in fact, if I waited another week or 2 pollen drops. Hope that helps some out there.
I had success using 1 to 9 dilution every 3 days untill day 21 of flower. But after understanding my ratio of sodium thiosulfate mistake, I feel they all would have reversed if given the correct ratio. So it seems 1 to 9 all the way up to full strength works. If your looking for a increased concentration, ive seen reports of 1 to 2, 1 to 3, and 1 to 7 working well for people. I think again what we are seeing is the 2 reasons i mentioned causing a lot of the mis haps. Make sure your mixing the right concentration and wait patiently for pollen drop. Like day 30 all the way to day 55 before pollen drop.
Thanks for your help.
I used 3.9 pent.
sprayed 5 days before flip and every 5 days afterwards. There wasn't anything to drop. No pod production, just regular female growth.
I'm going to make a new sts stock solution tomorrow.
I am going to try double the amount.
so twice the ratio would be the same amount of stock a (50ml) and the same amount of stock b added to half the amount of distilled water (450ml)
correct?
STS femmed seed has been known to produce a male every 5k seeds or so, and stray pollen is considered the main reason for higher numbers in a batch.What are the odds of STS treated seed producing a full on male?
What might cause this other than stray pollen from another plant?
