Re: Misting plants indoors??
I'd say the softener is worse than city water. The slight salt buildup isnt a problem tho. If your really worried do what I do and buy your plants reverse osmosis water from the RO machine at walmart- $.42 a gallon.
The whole leaving water sit out overnight to dissapate Chlorine is a myth, Cl is actually a very unstable substance, it breaks down almost instantly once its in contact with air.
It's only job is to kill any contaminates that may get into the water system while its still under ground. By the time you can get the water from your faucet, or even the end of the hose, onto your plants it is gone already.
