Rrog - I run no tills and switched from RO water to tap which is 284ppm, at least 70% mountain well water, probably 100% mid winter to mid summer at least.
Anyways, I couldn't be happier . No more trying to fit extra minerals in the soil and fucking shit up. LOL. I couldn't speak to the clogging though, I hand water everything.
I'm up over 400... pretty hard. The house uses a softener. Needs to.
I've been running the well water no problem, because I haven't been recycling soil. Once I move I'll be doing no-till, then I'm concerned.
