    I think you guys are misunderstanding me... AFTER using the RO filter, the water is 35-39. Normally it's 350-375ish.

    Mine is around 150. I don't worry about it. I use it for all my outdoor CPs. There's enough chlorine to smell it. The Sphagnum doesn't care.
    Where do we go when we just don't know,
    And how do we relight the flame when it's cold?
    Why do we dream when our thoughts mean nothing,
    And when will we learn to control?

    like crystal said, 150ppm will even work fine, but the key is that since her plants are outdoors, they will get top-watered by the rain. If you plan to use the tray method indoors, just make sure you top-water the pots every 2 or so weeks. I had a large pot that I filled the tray with 0-10ppm water for 6 months, and the plants started to decline. I top-watered it and tested the tds again and it read 300. So I rinsed it 100 times (almost not exaggerating) until the tds reading lowered to 50 ppm/got sick of pouring in water and waiting . Just goes to show you that a little ppm can go a long way.

    I use 150 ppm water in a few foot-tall sundew pots in my greenshed (a tiny greenhouse my pops and i built) and I top water every time. The plants are still doing great after a year of doing this.

    So the standing water was 300 TDS or the water coming out of your filter was? I haven't been worrying too much about the water once it's IN the trays, should I?

    Would a carbon post-filter be helpful to further lower the TDS?
