Test Equipment

To get the most out of your hydroponic system, it is a good idea to monitor the pH and the strength (conductivity) of the nutrient solution. This is not that important in gardens that don't recycle the solution as most hydroponic nutrients mix with tap water to a good pH and conductivity level. When recycling the solution, the pH and conductivity of the solution will change as the plants feed from the solution. By monitoring the pH and conductivity of the solution, and correcting it, you will get the maximum performance from your system.
