I really can't envision seeing all female cannabis plants growing in major traditional growing areas. From my understanding, sensi is fairly new, and showed up in the US in the early 80s. Prior to that, just about all marihuana in the US had seeds. Some more then others.

Granted, early cannabis growers, as with all early agriculturalists, did selective breeding per se, chosing the heartier plants. But, bothering to root out males was a waste of time, and would not have allowed for the genetics to evolve. Most cannabis was processed much differently then it is today, and all parts were utilized. Trace the true history, not the mythology or folklore.

Weed that I acquired in Southeast Asia in the late 60s was always very clean with no seeds, or woody matter period. It was all highly manicured and processed bud that was ready to roll. And it was bought by the match box. Seven match boxes made up about an oz, and it was $5.00 a box. :twocents:
