Bluelab Pen EC Meter

The ultimate practical solution for measuring conductivity (EC or ppm) and temperature! The Bluelab Conductivity Pen simply tells you that your plants have the right amount of nutrients in their solution and lets you know if any adjustments are needed. To feed plants well, we need to know what we are feeding them. Start with a quality nutrient. Measuring conductivity every day is the best way to prevent over-diluting or over-concentrating your nutrient solution. Completely change the reservoir solution every 7 days. Top up the nutrient level in between changes, so your plants always have the right amount of food. The Bluelab Conductivity Pen also measures the solution temperature, 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. To ensure plants can get to the food, you need to measure the pH of the solution. See our handy Bluelab pH Pen so you have all the tools needed to manage your nutrient solution. Now that's not so handy!
