Dont worry if you can’t find a non flowering shoot, works just as well if you pick the flowers off. My Salvias and Veronicas flower on every shoot, it works.
I top it up and change it if it gets a bit too cloudy. I wouldn't let it get stinky though. I put all different plants in a glass on the kitchen window sill and throw out the ones that are doing nothing after a while. That may be the wrong thing to do. I don't know. It'll be interesting to see how your experiment goes.

Maybe I'll try putting two lots of cuttings from the same plant into water, change one and not the other, and see if it makes any difference.
