Hesi pH Minus Grow. Reduces the pH level in the nutrient solution for plants in the growth phase
The right level of pH in the nutrient solution is very important. Too high pH is the cause of the formation of insoluble substances, too low pH is dangerous for the root environment.
The optimal level for most hydro-grown plants is: pH 5.8 to 6.2.
Nitric acid - HNO3, concentration 38%
How to use:
After adding all fertilizers, check the pH level in the tank. If the pH level is too high, it should be corrected with pH-. When using it for the first time, it is enough to add very little (a few drops), you need to adjust the appropriate dose for our nutritional solution and remember it for the future.
Always add ph minus to the water growth, never vice versa. (May lead to a sharp boiling or a risk of splashing.) Note, corrosive agent, use carefully, according to the label on the package.
