PPM or EC Meter for DWC?

I've read different forums where some say you don't need a PPM meter but a EC and I've ready others that use PPM meters. Too much research in too many forums can lead to contradicting statements haha.

What is recommended? I have a digital PH/Temperature meter but I'm confused on if I still need something for the PPM/EC and if so, which one?


Appreciate the help!

Yo should get one. either a ppm meter or ec meter. They both do the same job, and saying one is better than the other is like saying kilometres are better than miles

A PPM and EC meter are the same thing, measure the same thing, the EC of the solution. The ppm just converts ec to ppm.

Lots of info here and good prices to boot.

PH is necessary, I don't have a PPM or EC meter..

That's not saying I won't later, but for now I just use feeding charts precisely

Ahh, now I see. Thank you all for the info.

I grow in a hydro dwc and my Ph pen works fine, oh ya btw it reads in ppms..Theres a pic of it below

Nice! I purchased a Ph pen that shows temperature, glad to know your's works well.
