Growth Technology pH Probe Cleaner does exactly what it says on the label as it cleans salt deposit residues left by nutrients solutions when measuring the pH.
 
These deposits can give a false reading, meaning the solution might have a pH that's either too high, or too low, which could potentially cause problems with your plants.
 
Regularly cleaning your pH pen or meter with pH Probe Cleaner ensures readings accuracy, giving you peace of mind that your plants are getting exactly what they need at the correct pH.
Available in 300ml bottles.
