The Bluelab pH Pen measures the temperature of the solution, as root health is vital to the success of a crop. Plants get their nutrient from minerals, but they can only get all the right minerals they need if certain conditions are right. Think of nutrients like a lock. pH is the key. A key factor that affects food uptake is whether your solution is acid or alkaline. We measure this in pH.
Temperature affects the growth rate and structure of a plant so a solution temperature of 18 - 22˚C or 65 - 72˚F is recommended.
The hand held pH pen provides a compact quick and handy way to manage the success of your crop to ensure maximum uptake of nutrients.
Now isn't that Handy!
