IMHO plants grown from colchcine treated seeds probably should not be consumed. Those plants are only good for seed prodution not consumption, and is why this method is used by some commercial seed producers. I'm honestly unsure what the pros or cons might be of clonning directly off a plant that's seeds were treated.

And yes, stressing the plant to make it turn hermphodite produces female pollen that can be used on other plants (how I learned) to produce femmed seeds. Plants grown from these seeds will not be prone to turning hermie any more then the original plants the seeds came from. In fact if you only have one plant to produce seeds and you herm it and self pollenate it, those seeds even will not be any worst then what it came from. All mj plants will herm for self presavation of the strain, some just do it easier then others.
the pollen comes from the male part of the hermaphrodite plant. There is no female pollen. There is hermaphrodite pollen and Male pollen

Though yes, hermaphrodite pollen will make seeds likely to come out female; but they are also likely to become hermaphrodite also if introduced the seeds are introduced into similiar conditions during flowering that initiated hermaphroditism on the mother.

But it's important to always know in the back of your head that hermaphrodite pollen is hermaphrodite pollen and not 100% female; meaning your seeds stand risk of having both male and female parts.
daihashi Reviewed by daihashi on . Colchicine treating I've read from a few sources that crushing Colchicine tablets or extracting the raw colchicine from the winter crocus bulbs and soaking your seeds in it is the most preferred and used method to feminize seeds....anyone have any input as to this method of feminization?
