Is my EC ok for plain water?
Faegrowsstarted grow question 4y ago
Stupid question but the EC on my meter is it 0.3 or 3.7? I never really minded the EC just ppm as I grow in canna Coco plus but now I'm wondering if the EC is actually right. PH is usually 6.3-6.4.

It means your ppm is about 185ppm 0.37.
500ppm is 1.0 ec. 1000ppm is 2.0 ec Take your ppm and double it. This is the hanna reading.

So it’s not bad for tap water.. anything above .4 EC would be worrisome to me.
And yours is .37
