A hydroponics or nutrient pH tester is the same thing as a soil device – except you test your nutrient solution or hydroponic reservoir with it. These are very important, and should be used prior to every watering or feeding – unless you know for certain what your water pH is and you aren’t adding nutrients.

What is the most accurate pH testing method?

pH meters are the most accurate type of measurement and are widely used. Pocket-sized meters called testers are small, easy to use for fieldwork and relatively low cost.

What is the correct EC for hydroponics?

For most hydroponic crops, the ideal range of EC for most crops is between 1.5 and 2.5 dS/m. A higher EC could prevent the plant from absorbing nutrients due to increased (more negative) osmotic pressure, and EC levels that are too low could adversely impact yield.

What is the disadvantage of pH?

Disadvantages. One downside to using a pH meter is that the cost of the meter is significantly higher than using test strips. The pH meter is a long-term investment for gaining accurate results. For those who are going to be taking an occasional reading, test strips may be a better option.
