Bluelab Soil PH Pen

The Bluelab Soil pH Pen has a specially designed probe that allows this portable pocket-unit to test the pH of your substrate. Bluelab is a New Zealand based manufacturer that have been engineering and building water measuring technology for over 30 years! 

Correct pH allows your crop to uptake nutrients efficiently. Without monitoring your pH and EC levels, you're essentially growing blind. pH is a measurement of the acidity or alkalinity of an aqueous solution and should always be monitored in hydroponic/aquaponic systems to ensure that your plants are able to uptake nutrients effectively. EC is a measurement of the conductivity of water, or the amount of dissolved mineral nutrients in a solution.
