Measure pH directly in your nutrient line

Create the optimal conditions for nutrient uptake

All plants need a balanced diet of nutrients in order to thrive. However, your plants will only be able to access these nutrients if the nutrient solution is within a particular pH range.  

From a water chemistry perspective, pH (potential Hydrogen) plays a critical role in making nutrients soluble so that they can be absorbed by your plants. When your nutrient solution becomes too acidic or too alkaline, your plants won’t be able to access the nutrients they need.  

Create the optimal conditions for nutrient uptake by measuring pH directly in your nutrient line to ensure that this is always within the optimal range.
