Use General Hydroponics pH Up to increase the pH of your hydroponics nutrient reservoir, and pH Down to lower it. Use the pH Test Indicator to measure the pH.
Add a small ammount, allow to mix, then measure the pH. Repeat until the desired pH is reached.
To maximize plant growth, the pH of your nutrients should be slightly acidic. The ideal pH for most crops to fall between 5.5 and 6.5.
General Hydroponics pH solutions are buffered, making it easier to control the pH of your system.
