ELI5: How can plants survive hydroponically, but die from over watering in different environments?
gpt
Over watering plants can kill them in several ways. It can "drown" roots and deprive them of oxygen. It can interfere with uptake of certain nutrients, or it can promote fungal growth which can infect plants.

Hydroponic setups aerate the water to keep it oxygenated, and typically have some portion of the roots exposed to air. The water has specific nutrient levels in a form the plant can use. Fungi tends to do poorly in these systems because, unlike dirt, there isn't a lot of organic material to consume. That said, not all plants can be grown hydroponically. It's best suited for annual plants that have a short life cycle and doesn't work well for plants with specific soil needs.
