best early sexing tech?

i heard of putting a bag of a branch but branche dont form till later ...

would doing the 12/12 method after 2 weeks of veg stress the plant into a hermaphrodite?

hmmm..don't know if it will stress it into a hermie....but i think you should wait until it is mature enough to sex..like wait another couple weeks

yea u pretty much got it. just put a paper bag over one branch for 12 hrs of darkness and 12hrs of light. that single branch will flower while the rest of the plant veggs
