Bluelab – pH Replacement Probe

Just like humans, all growing plants need a balanced diet of nutrients (food) 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 growing solution becomes too acidic or too alkaline, your plants won’t be able to access the nutrients they need to grow.   
Get the fundamentals of growing right by regularly measuring pH to ensure that this is always within the optimal range.
