The BlueLab pH(potential Hyrdogen) Pen

The BlueLab pH(potential Hyrdogen) Pen is a necessity for every gardener. Plants need a well rounded diet just like humans, but without a balanced pH level they are unable to access those nutrients properly. Before a nutrient can be used by the plant, it normally must be dissolved in the soil through a solution. As a matter of fact, fourteen of the seventeen essential nutrients and minerals for healthy plants are obtained from soil. If a plant's pH is out of range, it will be unable to access or utilize any nutrients a gardener feeds their plants.

The Blue Lab pH pen can assist any gardener in determinig whether their solution is too acidic or too basic, or alkali. The majority of minerals and nutrients are more available in acidic soils rather than neutral or alkaline soils. We believe at Grow Green that a a pH pen is one of the necessary tools that will assist you in reaching a perfect pH level for your plants. When it comes to protecting your plant's pH, we know you won't be disappointed with the BlueLab pH Pen.
