Plants get their food from minerals - but they can only uptake those minerals if they are made bio-available by feeding at the correct Ph. Think of nutrients like a lock, and pH is the key. A key factor that affects nutrient uptake is whether your solution is acidic or alkaline, and we measure this in pH.The Bluelab pH Pen also measures the temperature of the solution, as root health is vital to the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 - 22˚C or 65 - 72˚F is recommended.This hand held pH pen provides a compact, quick and convenient way to manage the success of your crop and ensure the maximum uptake of nutrients.Teamed with our Bluelab PPM or EC Pen or Truncheon Meter, and you have a convenient and accurate system for ensuring optimum plant growth and health. - Keep your Probe clean and accurate by filling the cap with Storage Solution. - Keep your Probe accurate by calibrating with Ph4 and Ph7 Calibration Solutions. - Keep your Probe clean with the Bluelab Probe Care Kit.
