Although the matter of feminized seeds seemed most controversial in itself i once considered producing my own "AutoFem" seeds. Too bad "The Borg" (spider mites) had become a serious threat to my cultivation space, ideally on a windowsill...
At the time all i wished for was to enjoy healthy cannabis plants again, male or female: i only needed a senerity-promoting hobby while i was quite aware the parasites would re-emerge if i failed to address such issue 1st. Consequently i was prepared and ready to conduct a side-by-side experiment using 2 Cannatonic females in hope to explore/evaluate different concentration levels of colloidal silver, hopefully also as a miticide once I'd have identified concentration thresholds, one to kill the eggs without affecting the flowers, the other doing both. As i recall on-line literature appeared to suggest 1 ~ 3 ppm CS sprays to protect the plants while i'd have to aim for 25 ~ 30 ppm in order to produce all-females seeds.
M'well, at least i had the basic material required besides those 2 plants:
Notice how each coin has been drilled to facilitate support?... That's only the begining.
Unfortunately i can never forget how "social media" adversity just killed my enthousiasm for such ambitious project (especially for a newbie...) when discussing popular "simple" CS Generator designs, mixed with anthropomorphic "sex-reversal" jokes, over "bananas" for example... Etc., etc.
The initial difficulty was dirty CS generation with unregulated electolysis current response, similar to this:
Obviously the task called for constant low-current (1.6 mA) from a "high-voltage" source, featured with polarity reversal and associated period/frequency control for starters, because that would limit whiskers deposition. The matter of current density per donor surface was set but then there still was a need to determine a suitable distance between electrodes, water volume and maybe more...
So, eventually The Borg did come back to work as expected, just when my 2 plants were getting into flowering. The whole experiment could finally begin after months of patient preparation, but my desire for such challenge was gone. Because of the bannana jokes, etc.
Turning blue was no immediate concern because i was going to wash the spray after spidermite eggs would be dead, presumably in a matter of minutes. Which raised another question, how long does it take for CS Sprays to get absorbed by folliage?... Yet, in my mind a plant dedicated to producing seeds didn't also have to be suitable for human consumption anyway, but nobody could listen and stay calm so i cancelled the show.
Which is why i always approached these sort of topics with great caution thereafter: right after religion & politics there's the fear of hermaphrodite bananas using Colloïdal Silver, etc.
So... You've been warned: have your helmet ready!
Good day, have fun!!
