The Bluelab Combo Meter is a portable pH, conductivity and temperature meter all in one. AmHydro suggests testing your pH and EC at least twice per day to stay on top of optimal growing set up. If you are experiencing problems with yellow leaves, or slow stunted growth, the Bluelab Combo Meter will soon tell you if each parameter is within the plants requirements. Adjustments can be quickly made to get your crop back on track.
