The cuttings ability to "re-root" is stored in the stems, you want to take the cuttings after a long day of photosynthesis, the plant will fill its stems full of energy as part of its Kalvin cycle, during night cycle it rrthe plant takes that energy and puts it into root growth etc etc.
Possible but much harder, and environment must be kept optimal at all times, my current grow was from monstercropped cuttings much the same size, I fed them blue light for 6 weeks recovery, they ended up 6" tall with 12 internodes, some amazing things to be done.
Good luck.
