Hello,
I recently purchased a counter top R/O
system. Very simple, not so expensive. These will remove practically
all salts from water, and you can add fertilizer as you wish, without fear of
burns. You will have to adjust calcium and magniesium sometimes, but that
is as easy as putting some tap into the r/o once in a while.
These can be found in aquarium stores around
100-120 euros. Perhaps in the US, here are similar things. If you
have under 100 orchids, such a small thing will do just fine. It will make
15 liters per day.
:)
Best wishes,
Marianne
The household water filters like Brita remove particles, such as dust, pollen, and bacteria (and those copepods that have the ultra-Orthodox in NYC in a tizzy). As far as I know, they do not remove dissolved salts or chemicals. Letting your tapwater sit might improve the pH, due to dissolved air, but it will not remove any dissolved salts. Do you or any of your friends have a dehumidifier in the basement? That is the cheapest & easiest source of essentially distilled water. If you live in a private house, install a rainbarrel and store the water during the warmer months. When you absolutely have to use tap water, run it as hot as possible & fill up a bucket with hot water, then let it cool. Calcium dissolves better in cold water, so hot water will have less of it. That's why you get boiler scale in your teakettle. Iris I am not fat. I need repotting.
