I have a quick question about ec meters.
I assume that I can calibrate them to any ec solution? I noticed that the Blue Lab is 2.77 ec and the HM ec pens use solution that is 3+ec.
Also do you think the ec meter is the way to go or would a TDS meter be better?
I think I remember reading something about ec being more universal?
If you have a brand that has been reliable please send the name my way.
