For me, it's every 5 weeks. I have a 2 stage flowering room, so every 5 weeks I move a new crop into flowering, and a new crop into veg, and take a new set of cuttings.
you can clone from a flowering female but it will take longer to root then has to re veg for up to 6 weeks some strains it doesnt work with like a autoflower but success rate is 50/50 if your conditions are good. (personal experience and jorge cervantez book)
