Sometimes I’ll hermie a female cannabis plant during the flower stage and let it pollinate the other females in the room. It’s a cheap way to get a few thousand feminized seeds that can otherwise cost folks 5 bucks or more per seed.
Also (for you legal growers), do not save the hermie’s seeds. They will also be gender-confused. Just the ones from the normal females is what you’re after. Unlike the colloidal silver approach, you can still extract the cannabinoids after you harvest the feminized seeds.
In case you’re interested the Melbourne Cup is on at 11.59 pm Monday night New York time. (Actually it is scheduled for midnight - I said 11.59 pm to remove any doubt about the day).
