leave it full flower throw a plastic bag over the top of the flowers when they open tap the flower pollen into the bag keep that bag in the freezer then when u get a female get that bag and place it over one flowering stem for 1 day take it off boom u have seed cross breed with that clone thats what i would do
was only 4 out of my grow so not fussed, they have only been flowering for 2 and a half weeks so Im hoping I got them well before they would have released pollen.
