The Bluelab Conductivity Pen simply tells you if your plants have the right amount of nutrients in the solution and lets you know if any touch-ups are needed. Measuring conductivity every day is the best way to avoid over-dilution or over-concentration of the nutrient solution. The Bluelab Conductivity Pen also measures the temperature of the solution, as root health is vital to a successful 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.

Plants get their nutrients from minerals but they may not get all the minerals they need if certain conditions are wrong.
The ph it is a factor that influences the food intake for your plants. The Bluelab pH Pen measures the pH (acidity or basicity) and temperature of the solution, as root health is vital to a successful 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 pen pH by hand provides a compact and convenient way to manage harvest success to ensure maximum nutrient uptake.

The Bluelab Soil pH Pen offers a reading of the pH and temperature of soil and substrates in general. Thanks to this digital soil pH meter you can know exactly what nutrients are available for your favorite plants. In soil or growing media (not soilless) the pH strongly influences the availability of nutrients for plants.
It is now possible to closely monitor this operation and adjust the pH levels at the right time, to ensure plant health and above all optimal performance for flowering and fruiting plants.
Designed for use in indoor and outdoor soil cultivation, agriculture, horticulture and floriculture.

Bluelab Truncheon is the essential tool, when growing in hydroponics, to know the level of fertilizers in the nutrient solution. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can become dehydrated. Using the Bluelab Truncheon Nutrient Meter is the easiest and fastest way to measure conductivity! To take a reading of the solution, simply place the probe into the solution and the reading is indicated by the flashing lights.
Calibration of the Truncheon Nutrient Meter is not required.
