Probably genetics? Yes.
Flawed genetics? No. A male calyx or two, even a few, found on the FEMALE buds of a FEMALE cannabis plant, DOES NOT A HERMAPHRODITE MAKE!
If you don't understand genetics, more specifically biological evolution through natural selection, then you won't have any real understanding of why it is that this really does happen. And happen A LOT, regardless of strain!
Reread this sentence from the quote in my previous post.
They are a built in safety factor so in case of severe [sic] conditions, the plant can make sure that the species is furthered.
What does that mean? That's right! They evolved to do it.
IT'S TOTALLY NATURAL. It's not really a bad thing at all. Unless you wanna be a complete and total pot snob, afraid of even finding a SINGLE seed in your ENTIRE crop. Because if the plant is left alone to do it's NATURAL thing, and not harvested LATE, that's all your going to get from it, IF THAT! And you won't likely get rid of the trait very easily through any kind of breeding program anyways. It's likely common to ALL strains, and engraved deeply in ALL of their DNA from millions of years of natural selection/evolution.
FYI, It's called the bigger picture. How it's viewed is by thinking outside of that cubed container, a.k.a box, your thoughts are happily bound within. There are more stupid ass, ignorant, naive concepts derived from shear growing inexperience and/or lack of basic botanical knowledge regarding plants in general, but specifically this plant and how it grows, floating around this god foresaken place than I can hardly believe anymore. Do you people really believe all this crap? Based on what? Because somebody said so? Trust me on this, NOBODY HAS IT TOTALLY RIGHT! ESPECIALLY HERE. Think for yourself, do your research, carefully experiment with new ideas, make observations and base what you believe on YOUR OWN FINDINGS. Always remain highly inquisitive, yet highly skeptical(even cynical at times, if required, which it OFTEN is). Basically, NEVER allow yourself to think that you know it all, or worse EVER think that somebody else does. The rest comes from years of experience growing, PERIOD! AND NO, Ed Rosenthal DOES NOT know EVERYTHING! Or DJ Short, or whomever! I can find CONSIDERABLE inaccuracies in all of their supposed "teachings" on the subject, REGARDLESS of author.
