Introduction
Cannabis plants require a specific nutrient balance for healthy growth. One key aspect is the correct balance of parts per million (ppm) and electrical conductivity (EC) when using nutrient solutions. This guide explains how to achieve and maintain the ideal ppm and EC levels for cannabis feeding.
Understanding PPM and EC
PPM measures the total concentration of nutrients in the feeding solution. EC is a measure of the electrical charge in the nutrient solution, which indicates how easily the nutrients can be absorbed by the plants.

Optimal PPM Levels
For most cannabis plants, the optimal ppm range is between 500-800. However, this can vary depending on the strain, stage of growth, and specific nutrient requirements.

Adjusting EC Levels
The EC range should typically be between 1.2-2.5 mS/cm. This range allows for effective nutrient absorption without burning the plant roots.
Feeding Schedule
When feeding cannabis, it's important to follow a consistent schedule. Water your plants thoroughly before applying nutrients, and ensure they have a few days between feedings to prevent nutrient buildup.
Monitoring and Adjusting
Regularly check the ppm and EC levels of your feeding solution. Adjust as necessary to maintain optimal conditions for your cannabis plants.
