Can plants drown in hydroponics?

Hydroponics systems do not drown plants because the water is constantly oxygenated, circulated, filtered, and refreshed. The system is designed to keep plants from becoming oxygen-deprived.

How do hydroponics not get root rot?

Provide good aeration levels Making sure your nutrient solution has enough aeration is probably the most important step you can take to prevent root rot from occurring in your hydroponic garden. Adding additional air stones or hoses will only help.

How do roots breathe in hydroponics?
