quick water softner question

so my well water is awful but runs through a softener... guy at grow store says absolutly not and tries to sell me pre filters and r.o. .... its his job to make money. Are both of these required... seems i could just RO my already softened water. I have one friend who waters with his softener water and has no problems... any suggestions. will straight softened water work with nutes or do i need the RO... or do I need the pre and the RO with water from previous to softener. okay its mutiple questions .. sorry lol

For once a sales person is steering you right. Go RO. Even if you have to have to tap your main line BEFORE the softener and run a feed line through RO for your grow needs. Doing it like that saves RO membranes. Using water softened by salts opens up more problems for you. While it's OK to drink and bathe in the softening process makes it unfriendly for pot.

I have a buddy whos a plumber he can tap into it at any point... it would be possible for me to tap a seperate line post softner just for my grow... especially if it saves me on a prefilter system... and thanks hotrod... no straight softened.. got it.
