The difference manifests in the form of either pollen sacs or tiny calyxes armed with sometimes up to four stigma. Typically this occurs sometime after the production of alternating nodes.

I've included a crude MS Paint picture to give you a visual aid to what to look for in alternating nodes as well pictures showing the two sexes in their preflower form; first one's female and the second male.
Kush Over Reviewed by Kush Over on . Gender Question Well first off, I'm new to forum here. So hey everybody. I've been reading posts here and elsewhere and one thing has puzzled me. Some of the things I've read say a plant's sex is genetic but at the same time a number of people suggest there are certain factors (ie warmth) that can increase the likelihood of growing a female. I don't see how this could be if the plant's sex is genetic. So my question: Is a seed inherently a certain sex or do enviromental factors contribute to the gender? Rating: 5
