i'd take that top right off of her, the branch there in the middle...
you can do the water method, works fine, so long as, well, i'll just tell you what i do...
i have a kids sippy cup, plastic job, and it has a plastic straw built right into it.. wouldn't you know, the plastic straw fits and old airline i had laying around left over from my o2 boost buckets..
i strip the outer layer off the bottom inch or so of the clone stem with a clean razor blade, dip in gel or powder or w/e you prefer, then i put the clone in the sippy cup, run the air hose into the straw part of the sippy cup, then the other end to an air pump i had laying around.. the airline and pump keep the water nicely oxygenated, which i think helps greatly with the rooting... if you can't rig some sort of airline, i'd suggest just changing the water a lot as the oxygen gets depleted, at least once a day imo..
you can also put a humidity dome over the clones, and mist once or so a day till they root.. once you see roots, usually a week to ten days, strain dependent, then i put them in soil or rapid rooters or w/e i feel like using that day.. once they start to get bumps, you can take off the dome and stop misting them imo..
