Ony Posted June 16, 2013 Report Share Posted June 16, 2013 I have been caught short and can't get to my usual RO supplier so I'm going to have to find an alternative. Rainwater isn't an option and neither is tapwater. So far I've found references to Tesco value water being fairly soft and Voss artisan water is supposed to be 44 TTS. Can anyone confirm if either of those is suitable or give any better alternatives? Quote Link to comment Share on other sites More sharing options...
Richard Bunn Posted June 16, 2013 Report Share Posted June 16, 2013 No idea. At a push I'd use tap water that has been put through a Brita water filter. Last bottled water I tested (I think it was either Highland Spring or Nestle had a TDS of around 180ppm) Quote Link to comment Share on other sites More sharing options...
mobile Posted June 16, 2013 Report Share Posted June 16, 2013 Have you checked if your local aquatics shop offers RO water? - make sure they put it in a container that has not previously been used for saltwater though! Alternatively, the large supermarkets sell deionised water in either the washing aisle or the car maintenance section. The supermarket option is OK for small qualities, but gets too expensive if you have a large collection of plants. Quote Link to comment Share on other sites More sharing options...
Ony Posted June 16, 2013 Author Report Share Posted June 16, 2013 (edited) Thanks! I will have a look for the deionized water. I normally get RO at my local aquatics shop but I can't get there for a while so I just need an alternative to tide me over.

Ordovic Posted June 17, 2013 Report Share Posted June 17, 2013 Hardware stores and petrol stations may also have de-ionised water. Quote Link to comment Share on other sites More sharing options...
Stu Posted June 17, 2013 Report Share Posted June 17, 2013 (edited) Agree with the above - bottled water I would think comes in still in the 100-200 tds range as 'pure' or low mineral water tastes awful. They usually add some extra in to get the balance of taste right. You can definitely buy De-ionised 'pure' water from Asda if you have one near you. It's with the car maintenance section and comes in a 2.5 ltr white bottle for £1.19. http://groceries.asda.com/asda-estore/search/searchcontainer.jsp?trailSize=1&searchString=959953&domainName=Products&headerVersion=v1&_requestid=389916 As mobile says though, even at a relatively cheap £1.19, supermarket options are expensive as litres soon get used up in watering!

maxxima Posted June 18, 2013 Report Share Posted June 18, 2013 I'm using bottled water for all my CPs from drosophyllum to utrics. The label reads 56 mikrosiemens (don't know if that's TTS for you). I haven't had any problems. It might make a difference however that I generously top water all my plants including flytraps.

maxxima Posted June 18, 2013 Report Share Posted June 18, 2013 Thank you Mobile, I didn't realize it could be converted. This is very helpful to know. Quote Link to comment Share on other sites More sharing options...
Richard Bunn Posted June 18, 2013 Report Share Posted June 18, 2013 That's very acceptable in I suppose. Especially for small collections. Quote Link to comment Share on other sites More sharing options...
mobile Posted June 18, 2013 Report Share Posted June 18, 2013 I used to have to convert it regularly in my last job. There's a handy converter here, which saves getting the calculator out: http://www.lenntech.com/calculators/conductivity/tds-engels.htm 1 Quote Link to comment Share on other sites More sharing options...
Ony Posted June 19, 2013 Author Report Share Posted June 19, 2013 I did get the tesco value water and it tests at about 50 TDS. Not perfect but it will keep my plants alive until I can get to the shops next week:) Quote Link to comment Share on other sites More sharing options...
Richard Bunn Posted June 19, 2013 Report Share Posted June 19, 2013 50 is quite acceptable. Quote Link to comment Share on other sites More sharing options...
