Male or female?

they don't look to be projecting from a small twig. I'd wager female. should see a white hair-like projection at some point. if anything looks more like a grape rather than something nestled into the nook, it's male. preflowers will show at somepoint in vege. You can take a cutting, like you would for a clone, and simply stick it in a cup of water, with some nutes, and deprive it of darkness as if it were in bloom... within 7-10 days should see what the sex is. clean out glass every 1-2 days, refresh etc. just have to give it 10+ hours of uninterrupted darkness.. 11-12 hours of darkness is safer as there is potential variance.
