If you grow 4 plants get 2 female and 2 male and yank one male and save one male to pollinate the 2 females. How do you know when the pollinated plants are ready to harvest with mature enough seeds to save and use for the next batch? And how long do they need to dry before using them for another batch of plants? And should you pick one of the females early not worrying about the seeds figuring the other female will have enough.?
