Monitoring EC in indoor growing<\/strong> makes it possible to determine the concentration of mineral salts present in irrigation water or a nutrient solution. Along with pH, it is one of the most useful parameters for preparing irrigation water, adjusting fertilization and detecting possible salt buildup in the root zone.<\/p>\n

When fertilizers are added to water, the amount of dissolved ions increases and, as a result, electrical conductivity<\/strong> increases. However, a higher EC does not necessarily mean that the plant is better nourished. The key is to work within a suitable range for each stage, growing system, variety and water quality.<\/p>\n
