Why measure pH?
Understand the science behind healthy plants
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 a bsorbed 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 wi thin the optimal range.

Attention Valued Customer:
Ph testers and Ph probes are sensitive scientific equipment. They will require extra care and maintenance from the user (you) to ensure accurate readings, measurements and valid warranties.
Ph testers (without replaceable probes) and Ph probes are electrical sensors and considered a consumable item. You should aim to be replacing these over time as you do media, nutrients, etc. Probes and Pens (without replaceable probes) only have a 6-month warranty from date of purchase and will not be honoured without receipt of purchase.
Probes and Pens with proper care can last for years, but as it is a live charge in the electrode it can be finished from 6 months. Moreso if correct care procedures have not been maintanined. Hydroponic nutrients in particular degrade Ph probes much faster than other disciplines.
Probes must always be rehydrated before use in storage solution, available for purchase in store
Probes must be kept in storage solution when not in use (in tank monitors excepted)
