That would be incredibly bad luck. The worst I usually do is maybe 8 out of 10 male. Overall, I think the average is over 50% female. Personally, I think cannabis is predisposed to more females, because a single male can pollinate a whole bunch of females, so it would make sense for there to be more females. At least this is what General Buck Turgidson and Dr. Strangelove were all excited about.
