My last plant finally flowered, and she shows this node swelling trait more than any plant I've ever seen. So out of eight plants I have seen this on two out of four females and zero out of four males. In both cases the node enlargement was noticeable a few weeks before any flowers or preflowers showed. It seems as though if this is a valid identifier of a female plant, you would lose about half of your females by sexing this way. That does give me an idea for a breeding program though... *evil laugh* If anyone develops a strain that's reliable for this characteristic you all know I thought of it first!!

If anyone finds a male that shows this node enlargement please post it as I wouldn't mind having this idea debunked. Also if you have females with this trait I think it would be cool to post it here if anyone thinks it's worth keeping a running tally. Anyways, I'm done with this experiment, at least until I start more seeds, which may be some time since I have apparently found a very good plant to clone from and I will probably end up just growing her out for the next few sessions.
JD1stTimer Reviewed by JD1stTimer on . Experiment on different method of sexing cannabis I'm going to do an experiment on a different way to determine sex of plants. I heard this somewhere long ago, and I can't find where it was originally posted, but what it said was that plants which have swellings around their nodes are almost always female. I have eight plants growing, and as soon as I can sex them using the flowers I will take a close-up pic of the nodes and post them here so we can all find out if this is true or not. If it works it may be a good way for everyone who has Rating: 5
