Most common hydroponic crops thrive in a slightly acidic pH range of 5.5 to 6.8. Maintaining this balance prevents nutrient lockout and ensures optimal mineral absorption.
Ideal pH Ranges for Common Crops
Key Management Tips
-
Check daily: pH levels naturally drift upward as plants consume water and nutrients.
-
Target the sweet spot: Aim for 5.5 to 6.5 for most mixed crop systems to balance nutrient availability.
-
Avoid over-correcting: Rapid pH swings stress root systems. Adjust in small increments.
