After 9 weeks no sign of Male or female , 12 hour ...

See in picture 4/8 how there are whispy white projectiions from the little sacs at nodes? (only 2, if more that's male). Those are pistils. They are female bits. Check at nodes. If you see a bunch of grapes forming but no white pistil, it's a male plant. You have time before things develop. So, you can wait to be certain. As long as they don't open up, they won't release pollen, yet. Typically if it veges long enouhg, you can sex it. Sometimes you have to wait ~2 weeks into bloom to know for sure. A pollin sac will open up and a bunch of yellow banana-looking things will drop out in a bunch. When "nanners" grow out of the buds, that's a better of two crappy alternatives. A lone nanner dosn't typically have the same virility of a sac with nanners. You can pull lone nanners out while lime-green and tehy won't even be capable of pollinating your crop. Sacs are dangerous. One of those opens and tere's enough pollen to knock up every single calyx your plant has with the right airflow. So, a bunch of 'grapes' with no whispy whit projection is what you are looking for. 2 calyxes should grow at each node - those are femail with white projections. More than 2 is a bad sign. Watch for hemie in the developing buds too. sacs and nanners. If you see one sac, you could try to rip it off and keep an eye on it, but i'd only do that if you have 1 plant growing. I wouldn't risk others in same room or outdoor area.
