Probably about 2" a week, maybe more, maybe less, depending. If you make a
fresh stem-cut, strip the lowest leaf pair and bury it in gravel, you should
see roots begin to develop within a day or so.

how fast should healthy Bacopa caroliniana with more then adequate
fertalizer grow in moderate/bright light with a small fish load and no CO2
injection? an inch per week? inch per month? and how long do newly cut
shoots take to grow roots?
