I've used Silver Thiosulfate Solution (sts) for some time now. I have an organic chemistry background, so I thought I would put some of it to use with my cannabis hobby.
Over the years, I've purchased the solution, and finally come upon a formula that I've been using every since. I make my stock solutions fresh every time from both laboratory grade Silver Nitrate and Sodium Thiosulfate, Anhydrus. I weigh everything precisely accounting for molar mass to 3 decimals (one thousandth of a gram) As I stated before, I mix from scratch every time, so as to not have any loss purity or inactivation by exposure to light. I keep the product in a dark place and in brown (UV protected) spray and storage bottles. I have a meticulous and well practiced lab ethic.
Here is my Question: I've successfully made "fems" several different times, over several years. Never once had males, ever! Recently, I've also found that dedicating an entire plant is usually beneficial in acquiring enough pollen. Is it possible if the entire plant was blocked, that it might produce some male seeds along with female ones? Could I have turned a plant to male for real? Certainly (to my understanding) it doesn't seem possible, unless there was some male genetics in the genome from the start. Or a mistake?(and I"m reluctant this is the case here).
I can't explain this last seeding. I used feminized pollen, but approx 33% of my seeds stock turned out as male. Also, I was converting these plants from a photosensitive female (converted to male w/STS) pollenized into an autoflowering female. (several actually) It's results produced seeds that were 100% autoflowering, but approximately 1/3 of the resulting plants were males.
What (possible) explanation can account for these results? (beyond possible contamination with an unknown male) I'd also like to point out there's no examples of herme, but only 100% males and females. (I've got pictures to back this up), and the resulting progeny appear to have traits from both plants. (I will know more about this for sure at harvest)
