Every couple of days we take a walk through the hemp and pick out the male plants. No boys allowed! The males produce pollen sacks, which could open up and pollinate our females’ buds. This would produce seeds in the buds, which we want to avoid at all cost. The only solution to avoiding pollination is to take out all of the male plants, so every couple of days we take a walk through the rows and cut down any males we can find.
In the photos below, you can see the distinction between a male and a female plant. The male has many oval-shaped sacks, whereas the female has white-to-purple pistols that look like little hairs sticking out. The job of the pistols is to catch the pollen released from the male’s sacks to begin fertilization and seed production.
