It is important to mention that you must not consume any part of the plants sprayed with this type of product, although that would be weird, as the plants have "become" males and won´t produce any buds. Nevertheless, you shouldn't use the reverted plants to make resin extracts; the best thing is to discard them after harvesting the pollen. Both components, sodium thiosulphate and silver nitrate, are also used for photo-development.
This is another way to revert the sex of the plants, but this time using a solution made of 30ppm colloidal silver (that you can easily find in many pharmacies and also online) and distilled water. The solution must be applied for a few days until the plant starts producing male flowers, something that it´s not necessary with STS, where in most cases one single application is enough. Colloidal silver is formed by electrically charged silver nanoparticles and has antibacterial and antifungal properties. This product was introduced in the market in 1980 for therapeutic use. However, as with STS, you should get rid of the sprayed plants once their pollen is harvested, as colloidal silver is absorbed systemically by the plant and remains in its tissues. This sativa plant treated with STS started flowering as a female but soon developed male flowers. This is a method researched by Mohan Ram , who also conducted extensive investigations on plant sex reversal with STS. According to his findings, sodium thiosulphate (STS) is more effective in producing male flowers and viable pollen in female plants . Probably because of this, silver nitrate is mixed with sodium thiosulphate, instead of using it in isolation. Gibberellins are plant hormones that help regulate various processes related to the development of the plants.
There are several types of gibberellins available in the market, although the most common and effective is gibberellic acid or GA3 (Gibberellin GA3). This product is used in a very similar way to colloidal silver, sprayed on the plants during several days before switching the photoperiod over to flowering. It is worth stating that one of the side effects of gibberellic acid is a significant stretching of the treated parts of the plant, so don't be surprised if this happens to your plants! The recommended dose to achieve the best results is approximately 100ppm. Despite the fact that, after two decades of cannabis cultivation, many of the false myths surrounding feminized seeds have been debunked, from time to time we still hear some arguments like the ones shown below. As is often the case, many of these stories are spread by people who have never grown this type of seeds or have none or very limited experience with them. Ignorance is always a bad thing, and that's why we want to emphasize several points in relation to feminized seeds and the myths that often go with them; myths such as the following: Feminized seeds produce hermaphrodite plants: The problem with monoecious hermaphrodite plants has more to do with the parents used (and if they exhibit any hermaphrodite trait) rather than with the type of seeds produced. If to create a feminized seed you use a female plant with a tendency to produce male flowers , part of its offspring will likely inherit that characteristic, whether the said female plant is used as a pollen donor (after reversing its sex) or as a recipient of pollen (letting it flowering as usual). Yet the same thing happens when producing regular seeds: if the male or female parents are not stable in this respect, neither will be their offspring (or at least part of it). Feminized seeds produce mutant plants: Nothing could be further from the truth. It is true that sometimes some plants develop weird traits or mutations , although this also happens with regular seeds. Unfortunately, there seems to be not enough studies comparing the ratio of specimens with mutations of one or other type of seeds; however, given the millions of feminized seeds that have been germinated in the last 20 years, if mutations would pose a problem, the quantity of feminized seeds sold would certainly not be so high, and this would be a "public security" issue within the cannabis sector, both for the growers and the producers of the seeds. Feminized seeds have chemicals: This is another lie that some people believe. As it's been mentioned before, a female plant is sprayed with some chemicals in order to inhibit its ethylene action. After a few weeks of this and once in the flowering period, the plant will produce male flowers and pollen, which will be harvested to pollinate the female plants designated to produce seeds. Once the seeds are formed, they are collected and packed immediately, so they don't come into contact with any chemicals or the plants that produce seeds, nor, of course, with the seeds themselves. Also, to produce cannabis seeds , you normally need two separated indoor cultivation areas, one for the reverted plants (treated females) and the other for the females to be fertilized to produce the seeds, so the latter can’t get "contaminated" with any chemicals. Feminized seeds are GMOs: Once again, this is a false statement. We have already pointed out that by using these sex reversal techniques we inhibit the ethylene action in the female plant, and under no circumstances the seeds (or plants) are genetically modified . The sex chromosomes of the female plant converted into a male plant are still female (XX), nothing has changed at a genetic level.

Update: Five Years later and I still love this mechanic. So grateful that my daughter and I have a mechanic we can trust. He has gotten us through accidents and used car purchases. Ed was one of the friendliest people I've met, not only did he fix the problem I came in for but took care of several other issues.
