ELI5: How come plants in AeroGarden don't get root-rot?

Hello,

In an AeroGarden, the roots to a plant are submerged in water pretty much 24/7 (unless you let your Garden run dry which is a no-no). Yet I've never had a plant get root-rot.

Yet when you over-water stuff in a plant-pot, the plants are very likely to suffer/die from root-rot. Why?

Thank you!

The fungi that cause root rot thrive in high moisture, low oxygen environments. This is why overwatering causes issues; you remove the air pockets that are in normally watered soil.

Hydroponics consistently aerates the water. This removes the lack of oxygen issue associated with root rot. However, if the water isn't aerated, you can absolutely end up with root rot.
