A successful harvest is dependent on providing the proper nutrients to your cannabis plants. The pH of the growing medium can make it difficult for plants to properly absorb these nutrients. Here’s a guide that will help you understand the importance pH testing when growing cannabis.
What is pH?
Let’s begin by explaining what pH means. It is the pH, which measures acidity (or alkalinity) of a solution on a scale between 0 and 14. On a scale from 0 to 14, pH represents the acidity or alkalinity of a solution. Below 7 it is neutral and above 7 an acidic. You can influence how cannabis plants absorb nutrients by adjusting the pH level of your hydroponic solution, soil or coco coir.
Why is pH so important in Cannabis Growing
It is possible for marijuana plants to absorb nutrients in a certain pH range. Between 6.0 and 7.0 is the optimal pH for cannabis farming. You can make your cannabis plants less able or more resistant to nutrients by adjusting the pH.
How to Measure pH
Easy and vital is the ability to determine the pH level of your plant medium. The pH tester kit and pH meter are both useful tools to determine your pH levels accurately. Begin by taking small amounts of the medium you are using and mixing them with distilled. Now, use the pH meter/test kit to test the solution. You’ll have to adjust pH if you find it outside the range.
How to Adjust the pH
It’s easy to change the pH level in your plant medium. You can make the pH level lower by adding acid, such as citric acid or vinegar. A base like baking soda, potassium hydroxide or vinegar can help raise pH levels that are too low. Keep testing until you find the optimal pH range.
To grow cannabis successfully, you must maintain the appropriate pH level. The best way to make sure that your plants grow strong and healthy is by checking the pH regularly. The cost of a good pH test kit and pH meter will pay off in the end.
