I was wondering if anyone could advise me on the topic of water. In short, I collect alot rainwater which has lasted me all year without having to buy any large amounts of diironized water. However my sarracenia flava and dionea have spread like crazy and I plan to repot them into a bigger pots next year so their water need will go up and I have recently expanded the number of plants with 6 other small specimens of sarracenia. I do have a few tropicals indoors too. I was wondering whether a zerowater filter might be my answer, or should I consider a reverse osmosis unit (RO) ( but would my collection size be worth buying it). I've never tested my tap water but I am planning on getting a TDS meter to test it. I do have an outside tap but I have no idea how to setup a RO with it or whether it needs good pressure. Really appreciate your help.
