Description
GHE - General Hydroponics pH Test Kit is an afforable and accurate way to test the pH of your nutrient solution in a hydroponic system.
Simply half fill the vial supplied with your mixed nutrient solution, add two drops of test solution and replace cap without using your fingers to avoid contamination of results. Shake briefly and then reference to the pH colour chart on the side of the bottle. It's that easy!
Adjust your pH accordingly so that the nutrients are made accessible to the plants and are within range using our pH Up & Down
To maximise 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 maintaing the proper pH range because their 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 destabilise pH.
