If you want to pollinate the best time is when the female is 30 days into flower. Males tend to drop pollen before females are ready. I would offset it by a few weeks. Depends on how many seeds you want. You can always collect the pollen and use it when females are ready. I do both.Hey I got a question for ya. If you were going to breed a male with females do you initiate flower at the same time or would you offset the male from the ladies?
