but I know yall are stoned and easily confused like me.
A plant is not going to show sex or flower until its sexually mature and this usually won’t be until it reaches 6 or 7 true nodes, sometimes more. If you put a plant in 12/12 it still needs to be sexually mature before it flowers or shows sex.
I've had a look at Montana a few months back and though sex determination is entirely possible by their supposed means, I don't see, not even with a lot of imagination, how they would test for 'hermies' nor what they mean with true hermaphrodites...
The bad thing so far (at least until early this year, things change fast especially with the cannabis genome project in mind) is that there are only reliable markers for males. In other words, no result means female which is not as good as a clear readout.
But give them a shot, maybe also with a known male and female sample as control?
