The Bluelab pH Pen also measures the temperature of the solution as root health is critical to the success of a crop. Temperature affects the growth rate and structure of a plant. Therefore, a solution temperature of 18 - 22°C or 65 - 72°F is recommended.
The handheld pH pen offers a compact, quick and convenient way to monitor the success of your crop to ensure maximum nutrient uptake.
In conjunction with our Bluelab ppm or EC Pen, you have a convenient and accurate system to ensure optimal plant growth and health.
