Bluelab pH Pen/Temperature
Bluelab pH Pen
The ultimate handy solution for measuring pH and temperature!
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.
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 18-22C or 65-72F 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.
