The pH Test Kit by General Hydroponics is a complete kit for measuring the pH levels in your hydroponic system’s nutrients. The pH Test Kit includes a testing tube and test indicator to determine how acidic your nutrients are. Not all nutrients are pH buffered, and it’s important to keep it within the 5.5 to 6.5 level range.

pH Adjusting Solutions. Achieve perfect pH.
To maximize plant growth, the pH level of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. pH can acidify to an unacceptable level when nutrient solutions are used with poor quality water, or pH unstable media, such as rockwool. High growth rates can also destabilize pH.
