After Finding A Pollen Sac

Finding one banana on a feminized plant in week five does not have to mean binning the whole crop. If it is a single sac, it can be removed cleanly with tweezers, and then the entire plant needs checking, not only the branch where it turned up. That is the procedure given at https://queenfeminizedseeds.com with the reminder that one sac opening unnoticed can seed a whole room. When new ones keep appearing every few days, I would pull the plant, because the rest of the tent is worth more.
