Hi
(I) think the best way is:
Take a clone(s) from your plants befor flowering.
When the sex of your original plant(s) are determinged.
Throw away any males and keep the female clones.
When I have taken clones form a regenerated flowered plant, the clones did not root as well.
By the time the original plants have flowered, harvested and dried, you will be able to take clones from the original clone.
It takes me about 8 10 weeks to be able to get clones from a clone.
Hope this helps.
PS It take me about 9 weeks flowering and 2-3 weeks drying/curing, by then my clones are ready and I can get 10-15 clones of it.
