take a clone from the female plant...now.yeah I didn't really think of that.. Would I be able to harvest most of it, then just keep it under 12/12 until it starts throwing balls, collect the pollen and then brush it on the next gens buds? These will generally be female too right?
put it under 24 hrs of light until it reveges....you have a flowering clone
take the same plant or another plant..or another one and keep it blooming till the end...and then a lil bit more....the plant will produce "bananas" which contain female pollen.
save the pollen
when your clone(s) are ready to flower then pollenate the lower buds
you will have female seeds when done
