For almost a decade now people on pot boards and in hydro stores have been trying to convince people that they need R.O. water to grow and that they will have a superior product if they do.
First thing that people need to know is that the nutes you buy have been formulated to work with tap water, not R.O. This means that you will have to put back a lot of what you take out, which is one of the reason the people in the hydro store highly recommend R.O. because they have an app for that.
This doesn't mean that some people don't truly need an R.O. filter, just that the majority of people don't, and a lot of people who don't need it use it.
Personally I wouldn't ever buy a R.O. filter for any tap water under 300ppm and up to 500ppm I would at least try a grow before spending big bucks on an R.O. filter and the cost associated with it (cal-mag, wasted water down the drain).
I often hear people who come out in support of R.O. filters say stuff like "god knows what's in there." Actually there's this thing called the net, took me about 10 seconds to find last months water analysis for Boston tap. Took a look through and it looks pretty good to me, even has Silica in there which is cool because people spend big bucks on Silica.
So my advice to new grower thinking about R.O. is don't let people convince you need it, or even that you don't need it. Find out for yourself, get your water report, find out your ppm and even try a grow. Remember there are far more growers making more weed with tap than there will ever be with R.O.
