ELI5: why do plants get root rot from overwatering, yet you put cuttings in just water to grow new roots? And also just like what’s the difference between that and hydroponic gardening in general?

So, plants grown in hydroponic systems can still get root rot— however... Properly installed hydroponic systems should contain air pumps that help to supply O2 to the plant, as well as a drainage system (ebb & flow system). Root rot occurs in waterlogged soil where O2 is mostly inaccessible.

It might be more helpful to view root rot as the plant's problem. It's not that there's anything wrong necessarily with being in water; it's that the plant is diseased.
