The target pH range for nutrient solutions is usually between 5.5 and 6.5. This allows for nutrients to be more readily available and effectively absorbed by most plants. A pH that is too high or too low can lead to nutrient deficiencies or toxicities that could harm the plant over time if it’s not corrected. Having the right pH is especially important for water-based hydroponic systems.

To measure the pH of your plant’s nutrient solution, you can use pH test strips or a handheld pH meter. Test the nutrient solution two to three minutes after adding the nutrients to the water in your reservoir. If the pH is between 5.5 and 6.5, you are good to grow. If not, you will need to either raise or lower the solution’s pH.

pH test strips are a great, easy way to measure your pH.
Handheld pH meters are another great way to measure your growing solution.

If the pH is too high, add Root Farm pH Balance Down in small increments, testing the pH frequently until it reaches the desired level. If the pH is too low, add Root Farm pH Balance Up following the same method.

IMPORTANT: whenever using these products to adjust the pH of your solution, be sure to wear protective gloves.
