Zaitun, When cutting rots in water, it is really stinky. I played around with rooting in water, using aquarium with an aquarium heater, pumps to move water, aeration & thermostat ---- I would say, it was experimental and I would not do it again especially after discovering spaghnum moss(SM). Roots were brittle and rot contemination, washing cuttings, changing water and certainly more work. I find success rate higher using SM & less work + I don't need to keep monitoring.
