Thank you @litguru.
It's always nice to enjoy a good toke with the plants while admiring their mystique.
The dominant Sativa traits in these genetics usually show sex at 4-5 weeks. The males (pollen sacks) usually around 4 weeks and the females (the pistils) usually around 5 weeks.
Determining the sex is quite easy with cannabis. Pollen sacks (male plants) are pretty unmistakable with a ball/spade shape sacks, and they do not shoot pistils. The wispy pistils are a female trait only and produce the desired buds.
Currently at 54 days of vegetation and will probably be at about day 80ish when I induce flowering, and flowering will probably take about another 8 weeks lol.
It looks like it requires some patience and diligence to grow plants, but the results are so satisfying. Sativa is my favorite because it perks me up. :)
