if plants rot when overwatered, then how can they grow in hydroponics?
cause roots are always in the water when using hydroponics (instead of soil, water and nutrients are used), so I'm wondering how can this grow.
The reason the plant's roots die is because they can't get any oxygen. In a hydroponic system, the water containing all the nutrients also contains oxygen and it is usually constantly circulated.
When you overwater a plant in a regular pot or in the ground, the water displaces the oxygen.
