CANNA -pH MINUS GROWTH lowers the pH level in the nutrient solution for plants in theGROWTH PHASE.
The correct pH level in the nutrient solution is very important. A pH level that is too high causes the formation of insoluble substances, a pH level that is too low is dangerous for the root environment.
The optimum level for most plants grown in hydro is : pH 5.8 to 6.2.
Directions for use:
After adding all fertilisers, check the pH level in the tank. If the pH level is too high it should be corrected with pH-. The first time you use it, just add very little (a few drops), adjust the correct dose for our nutrient solution and remember it for the future.
