i have never seen clones in water before, i have always taken mine straight from a mother plant , straight into rooting hormone gel and then straight into a rockwool cube , then they sit in the holders that come with the cubes and in a tray with water, i mist them as often as possible and i have never lost a cutting (i have chucked some before that looked weak), drooping is normal and occures around day 2-3 after being clipped from its mother and they normally take around 24-48 hours to pick back up......i would remove those bags sit back, mist often and watch..........
