    Distilled is probably safer for your sensitive plants because it is more reliable. RO systems work great but require maintenance and monitoring. Source water quality, prefiltering, pressure of the system, type/quality/age of the filter membrane all determine what the quality of the RO water is. If your running an RO system you need to pay attention to it and monitor it. Even under the best circumstances the RO membrane will slowly degrade and the RO water along with it. In many areas of the country where water is metered and cost alot, a deionizing system is cheaper for larger scale production. These systems if prepared correctly will give water nearly as good as distilled.

    I think you can also hook up a deionizing unit to your RO tank and have it further filter it there.

    The system I stuck together presently is like this:

    Tap water TDS = 300-400 ppm-->

    5 micron sediment pre-filter -->
    activated carbon prefilter for chlorine and chloramine -->
    Thin Film Composite (TFC) R.O. membrane -->
    Mixed bed de-ionization tank -->

    Final product water TDS = 0 (no measurable ions) 18 Meg Ohms

    Years ago I discovered how corrosive this water can be to ordinary solid brass fittings. . . ate them away in less than 1 year.

    It may be technical Darcie but it is worth saving an expensive plant's life. The excess minerals in the water wouldn't kill even an unhealthy plant off right away it would be at least a month or so depending on the concentration of the TDS in the water before the minerals built up to danger levels in the soil.

    There are no ill effects from drinking RO or distilled water.

    RO will vary in quality depending on many factors so you have to be careful that it is good quality. Another place to check might be a high quality pet store. Sometimes they sell pure water for people keeping sensitive fish/coral etc.

    be very carful when drinking ro, airborne bacteria can infect it and make you very, very, sick, maybe in the hospital! [img]http://www.**********.com/iB_html/non-cgi/emoticons/sad.gif[/img] IF you don't cover and refrigerate it, but if not refrigerated and/or covered, it dosen't affect the plants. [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    oh and it can infect it cause there is no clorine!

    (sorry about my spelling, guys)

    I drink ro and disstilled because californias tap tastes like (I used to live in colorado, so I'm going to say) colorados toilet water! (if you lived in oregon, you would say oregons toilet water!lol
