Bluelab EC Pen - Conductivity/ppm

Handy measurement of EC (or ppm) and temperature

The Bluelab conductivity pen simply tells you if your plants have the right amount of nutrients in the solution and lets you know if 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 avoid over-dilution or over-concentration of the nutrient solution. Completely replace the tank solution every 7 days. Reload the nutrient level between changes, so your plants always have the right amount of food. The Bluelab conductivity pen also measures the temperature of the solution, as root health is vital to a successful crop. Temperature affects a plant's growth rate and structure, so a solution temperature of 18 - 22 ° C or 65 - 72 ° F is recommended.
