Some varieties require an environmental stress to express inter-sex. This is genetic based also.
Inter-sex plants are of many different types, from all branches with male and female flowers, to a few male flowers on female plants that only show up on the tips of the buds and often don't open or release pollen.
And everything in-between.
Plants also have a male and female flowering habit, with male being tall and thinner flowers, while females have squatter denser flowers. Males can have the female growth/flowering habit, females the growth/flowering habit.
There are up to seven types of flowering profiles, ranging from pure male to pure female with everything in between, which are used as guidelines in selecting desirable plants. The most desirable types are mostly female in appearance, especially the flowering tops, and only develop a few male flower clusters which rapidly release their pollen and fall off.
This is used to in maintaining Monoecious varieties, an elaborate system of categorizing cannabis plant types, in order to select only those with the most stable proportion of male and female flowers.
Enough for now.
I have found some Kandy Kush (OGxTrainwreck) plants will produce a bunch of male flowers about 10-20 days into flower, and pollinate the very first pistils that occur. Then the plant seems to go back to being a full on female, usually ready about day 75-85 with fully mature seeds. The plants produce roughly 50-100 seeds per 50-100 grams of herb. For a separate breeding of a product I can release, I am using as female plants as I can find(hopefully true females never showing any male flower). For my own research and enjoyment(I do love this strain!even the hermie's smoke wonderfully) I have started making an IBL out of these early hermie females. I am going to make a few parallel lines to start, its a very easy project because these type of plants self each time you grow them, so just keep growing them and keeping the seeds when they happen. This line is my desert island strain, but it would be perfect as you would never need males, yet still get seeds to continue next crop. Definitely not a release for the public,but very interesting to me.
