We have the solution to your PH problems. As a grower, in most cases your PH level is vital. To measure your PH we offer simple colour test strips or everything from budget digital meters to professional food grade PH monitors and meters. We also provide PH up and down to get you to your magic number. Every PH meter needs to be calibrated once a month minimum. To do this we provide PH buffer liquid to make your meter like new. All of our liquid solutions come in 20ml packets up to litre bottles.
