Might have something to do with where he livesLowe's on sale is $130 or so....cheap? Buy distilled. How do you not have access to rainwater? Go up on the roof and put a bucket out.
Plants do well if you set out a jug of water and let the chlorine evaporate.

Those are more just simple carbon filtration... OK for drinking water, but it won't remove nearly as much as an R/O filter will.Is it possible to use water filters like Pur instead of an RO system?
