Essentials pH Buffer 4

Ensuring growers keep their pH meter calibrated is key to maintain accurate readings. If your pH meter gives off false readings then growers are at risk of having incorrect pH levels in their nutrient solution. Essentials pH Buffer 4 will accurately calibrate your pH meter. pH meters require calibrating regularly.  pH buffer 7 is the most popular but for more accurate 2 point calibration it is advisable to use pH buffer 7 in conjunction with buffer 4.
