Yeah, we have a filter connected to our fridge...gonna replace it, but its PPM is about the same. a little lower when the filter is new
I actually grew my plants outside using well water (I thought it was good before droseraguy tested it). Turned out to be ~350 parts per million. My nep looked better than ever, and the sundews didn't look too shabby. I think the occasional top watering of rain we got (once or twice every 2 weeks) was enough to keep minerals from building up.
I wish I had tap water that clean. Ours is 490 to 550 out of the tap! So I make weekly trips to buy ro water. Count yourself lucky to have such great water.
All the best,

Ron - it depends on the time of year.
My temperates are obviously outdoors all year, but my neps are inside during the winter and outside during the summer - but ive got a greenhouse going up here in a week or so thats going to change.
I imagine i will get some RO water, and once every few months flush the pots with the RO water and just water with the tap water.
