I agree with Greene. There are lots of studies that have been done on water rooting vs in soil. Roots done in water appear to be less stable as they have adjusted to light being on them. Being placed suddenly in the dark make them even less stable and much weaker. I would follow Green's advice.
You seem to have done very well with your plants. Trial and error teaches us many things. Mostly what works best for you. Good luck with your plants!
