This informative video from Nature Tech highlights the significance of Electrical Conductivity (EC) in maintaining a balanced and effective nutrient environment for hydroponic plants. EC measures the concentration of dissolved minerals, particularly essential nutrients like nitrogen, phosphorus, and potassium, that plants require to thrive. Regular monitoring of EC ensures that plants receive the appropriate nutrient levels throughout all growth stages.
The video provides guidance on using a digital EC meter, starting with measuring the base EC of clean water and then calculating the desired final EC level based on the specific requirements of different plants. For instance, many plants thrive within an EC range of 1.2–1.6 during vegetative and 1.8–2.2 during flowering or fruiting. It is advisable to group plants by their growth stage and type to manage EC, pH, and other conditions effectively.
You will also learn how to adjust high or low EC readings to prevent issues such as nutrient lockout or deficiencies. The video emphasizes the importance of changing the reservoir monthly to avoid buildup or imbalances. Additionally, Nature Tech's plant encyclopedia offers tailored EC and pH guidelines, helping gardeners succeed and grow confidently, regardless of their experience level.
