The conductivity solutions are made of high quality Potassium Chloride with different strengths. The solutions are standardized with a conductivity meter, calibrated by high purity NIST 999 Potassium Chloride in deionized water. The concentration is also confirmed by NIST 2201 Standardized Silver Nitrate solution. 1382 ppm (mg/l) at 25C
Frequently Asked Questions
Q: What is the suggested pH range for my hydroponic system and soil plants?
A: Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.
