Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range. This user-friendly and hardy handheld pen will take measurements in increments of 0.1 pH and is fully temperature compensated, so you can expect accurate readings every time.
