CBD hemp flower refers to the bud that grows on the "female" hemp plant. The difference between "male" and "female" hemp plants is that the former cannot produce flowers. Therefore, you can only obtain the hemp flower from the "female" family of the hemp plant. Seed production begins as soon as the hemp flower has reached full bloom. Then, the bud secretes cannabinoids to attract pollen from the "male" plants. In order to be able to produce CBD hemp oil, manufacturers isolate the seeds and extract the oil.
