Wilt? Wilt can be caused by a number of things from drout conditions, cold temps and stagnant water, to saturated soil, consistent high humidity and salinity issues.

Back in the old days it was widely parroted that water had to be filtered or purchased to get a quality result. But they also touted collected rain as better than tap. This sounds nice in concept, but rain is generally acidic with many, many industrial contaminates it absorbs traveling through the atmosphere. I'd rather use my wellwater.

If you don't mind purchasing an R/O and the future filters it'll take, or if you don't mind going to the store to heft cases of bottled water at $5.00 a pop, or if you don't mind spending extra dollars replacing the crap filtering takes out...then I wouldn't really bother checking if your water works just as well.

It can take an experienced eye, but watch for marketing hype and bullshit. It can lead you astray for years, and the costs build-up over time. Junk science is a great marketing tool though. Half-truths and misdirection. Nothing overtly damaging, but definately profit-driven. And if it screw's-up your plants, that's ok...they have an ammendment to fix what the first product caused... :wtf:
