Grtk pH Down
pH Down will adjust your solution to the desired pH level. Add a few drops of pH Down to your solution tank to raise/lower the pH level in the tank. Our pH solution is concentrated so adjust slightly before adding your final nutrients. After adding the nutrient materials, test your solution to determine if the exact level has been reached. It may be necessary to add a few more drops to reach the desired level.
Directions for use:
Test pre-existing nutrient solution and if pH is too high, add a few drops of pH Down. Re-test pH level of nutrient solution and add pH Down as required. The optimum pH level for most plant growth is 5.5 – 6.5. Use only as directed.
