The ultimate handy solution for measuring conductivity (EC or ppm) and temperature!
The Bluelab Conductivity Pen simply tells you that your plants have the right amount of nutrient in your solution and lets you know if adjustments are needed. To feed plants well, we need to know what wexe2x80x99re feeding them. Start with a quality nutrient.
Measuring the conductivity every day is the best way to avoid over-diluting or over-concentrating your nutrient solution. Completely change the reservoir solution every 7 days. Top up the nutrient level between changes xe2x80x93 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 the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 xe2x80x93 22xcbx9aC or 65 xe2x80x93 72xcbx9aF is recommended.
To make sure the plants can get at the food, you need to measure the pH of the solution.
