Growers of cannabis know it is vital to give their plants the correct nutrients in order to produce a high-quality crop. If your medium pH is too low, the plants will not absorb the nutrients that you have given. To successfully grow cannabis, pH testing is crucial.
What is pH?
Let’s define pH. The pH scale measures the acidity and alkalinity of a solution. It ranges from 0 to 14. A pH value of 7 signifies neutral. Anything less than 7 means acidity. Anything higher than 7 means alkalinity. Your cannabis plants will absorb nutrients in a different way depending on the pH of their growing medium (soil/coco cooir/hydroponic system).
Why is pH important in Cannabis Growing?
For cannabis plants, the optimal pH range is between 6.0 – 7.0. This pH range allows the plants to absorb nutrients easily. The pH range that is best for cannabis growth should be between 6.0 to 7.0. The pH level should fall between 6.0-7.0. This will ensure that your plants can absorb nutrients.
How to test pH
It is very easy to test the pH of your growing medium. The pH tester kit and pH meter are both useful tools to accurately measure the pH level. You can take a small amount of the growth medium and mix it with distilled waters. Then, dip your pH-meter into the solution. Then, wait for the reading. If pH levels are not in the optimal range, you can adjust them.
How to Adjust pH
You can adjust the pH of your growing medium easily. If your pH level is too acidic (alkaline), then acid like citric acid or vinegar can be added to lower it. Baking soda and potassium hydroxide can be used to adjust the pH. The pH level should be adjusted gradually and then tested again to confirm that it is within the desired range.
Final Conclusion
The correct pH level is vital to ensure cannabis grows well. It is essential to regularly test your pH level and make adjustments as needed. This will ensure that your plants absorb the nutrients necessary to grow strong, healthy and happy. A pH test kit and pH meter is well worth the investment. This will allow for you to save much time and money.
