Starting with good quality (low EC) water is assumed. If you are starting with low EC water, the bulk of the EC will come from the base nutrients.

*EC units are expressed in microsiemens. 400 microsiemens = 0.4 millisiemens

Quality of Starting Water:

As water transpires from plants and evaporates from pots it causes EC of the remaining nutrient solution to increase. If you are unable to fertigate frequently, then it will be harder to maintain a tight range between inflow and run-off EC values.

The EC that matters is the EC of the nutrient solution suspended in the coco at the root zone. However, you can only measure the EC of the inflow and the run-off. The run-off EC is the best proxy for the EC of the nutrient solution in the coco. For this reason, your main task is maintaining the run-off EC within the acceptable range.

General EC Ranges for Cannabis in Coco

Nutrient companies should provide you with both a set of recipes in a feed chart and a set of EC or PPM ranges for each stage of growth. The general ranges provided above are appropriate for General Hydroponics Flora Series. If EC or PPM ranges are not provided, you should use the general ranges recommended above. When calculating your target inflow EC, you need to start with the low end of the recommended range.
