Keep your plants healthy and growing strong! Growth Technology – pH Buffer Calibration Fluid is the key to ensuring that you get precise measurements every time. This flexibility allows you to calibrate your meter for optimal accuracy and maintain nutrient solution at the correct pH level, so each plant can reach its full potential with just one use of this helpful calibration fluid! See what a difference proper calibration makes in promoting robust growth for all of your beloved greenery.

The Growth Technology – pH Buffer Calibration Fluid package includes your choice of pH buffer solution – pH 4 or pH 7.

Before use, it’s essential to give your pH tool a thorough clean. To guarantee accurate readings and an optimal experience when testing the pH levels of various solutions, run through a simple test with one of two buffer solution options – either 4 or 7 depending on which you’ve got handy! However take caution – mixtures between these Up and Down solutions can become volatile if mishandled, so be sure to keep them out-of-reach from young children as they are corrosive in nature & could cause skin irritation/burns if touched without care.
