## Description

Plants get their nutrient from minerals but they can only get all the right minerals they need if certain conditions are right. Think of nutrients like a lock. pH is the key. pH measuring equipment must be cleaned and calibrated regularly to ensure they are giving the user accurate readings. pH instruments are calibrated to pH 7.0 first (buffer) then to pH 4.0 (slope). PH measuring equipment must be cleaned and calibrated regularly to ensure they are giving the user accurate readings. pH instruments are calibrated to pH 7.0 first (buffer) then to pH 4.0 (slope). The perfect solution to store and hydrate your pH products. Bluelab knows it is extremely important to care for and store pH probes correctly. pH probes are sensitive glass instruments which age through normal use. General hydroponics pH up & down effectively maintains pH levels in nutrient solution. The acid formulation uses food grade phosphoric acid to maintain the pH to the proper level. This powdered acid formula is easy to handle and ship. Lightweight in comparison to liquids.
