How Overaeration Impacts Oxygen Levels in Roots
Roots rely on a delicate balance of oxygen to fuel respiration and nutrient uptake. When dissolved oxygen levels spike beyond this range, the same molecule that sustains life becomes a silent stressor. Overaeration is common in deep-water culture, nutrient-film technique, and high-pressure aeroponics where growers chase “more is better” without realizing the hidden ceiling. The…
