pH and EC Levels:

Maintaining the right pH level of the nutrient solution is crucial for nutrient absorption. Additionally, monitoring Electrical Conductivity (EC) helps ensure the correct concentration of nutrients.

Optimal pH Range: Generally, the optimal pH range for most hydroponic crops is between 5.5 and 6.5. However, this can vary slightly depending on the plant species. It's essential to regularly monitor and adjust the pH to keep it within the desired range.

Adjusting pH: pH can be adjusted using pH up (alkaline) or pH down (acidic) solutions. Automated pH controllers are also available to maintain a stable pH level.

Electrical Conductivity (EC) Levels:

Importance: EC measures the concentration of dissolved salts or total dissolved solids (TDS) in the nutrient solution. It provides an indication of the nutrient strength in the solution.

Optimal EC Range: The optimal EC range varies depending on the growth stage of the plants. Seedlings and young plants generally require a lower EC, while mature plants in the flowering or fruiting stage may need a higher EC. Recommended ranges typically fall between 1.2 to 2.0 mS/cm.

Monitoring and Adjusting EC: Regular monitoring of EC levels is essential to prevent over-fertilization or nutrient deficiencies. Adjustments can be made by diluting the nutrient solution or adding concentrated nutrient solutions to achieve the desired EC.

Interaction Between pH and EC:

pH-EC Relationship: pH and EC are interconnected. Changes in pH can affect nutrient availability, and changes in nutrient concentration (EC) can influence pH. It's crucial to strike a balance to ensure optimal nutrient uptake.
