I believe the seed theory is also correct. I bred some feminized (Fem to stressed fem) seeds and they all have the round features on the seeds. This also holds true for hermaphrodites from what I have seen so far.

The original post, not sure where I saw it, but I have been watching this. I recently sprouted 2 regular seeds, one had the round and the other had an oval at the end. Not sure which ended up which, but I got one female and one male out of the deal. Sorry I lost track of which was which, this is the one that has not shown any red.

I also believe that to say this will always be true is a fallicy. It is a generality that I have noticed and have tried to apply as a theory. Just another little tool to put in the gardeners grow tool box. I do not think I would, as a business, rely on the appearance of the seed to say it is female. You have to know the genetics to be positive.

Yes, this is a fun thread, quite lively and interesting.

I believe it was about sexing from unknown seeds and not clones. The post indicated that "sex" could be determined well befor pre-flowers.

The purple may appear in the whole plant, just the stem, just the the leaf shoots, or a Rating: 5
