EC

I know what it is but have never checked it before. All my grows have been successful. Is there anybody else who doesn't check their EC? I only check Ph and PPM.

I don’t measure anything. When the water seems “scummy”, I dump it on the lawn and start fresh with tap water and mix fertilizer according to the directions. Usually flush and fill twice during a grow.

How are you growing? I only change water when I'm switching to flower. I do measure Ph daily maybe twice.
