That said, the distilled water from Wal-Mart is easily going to be the cheapest option for purchasing pure water.

I found a local aquarium supplier that sells RO/DI water(0-1ppm) for 30¢ a gallon. Two 5 gallon containers = $3.23. Sweet deal!

Many, probably most, SW/Reef shops sell RO or RODI by the gal. It's been ~$0.25/gal for a long time, but with the current inflation $0.30/gal still sounds good.

my dehumidifier water reads at 30 ppm.

What amount of TDS is fine for all carnivorous plants?

Anything below 50ppm TDS is considered safe for all CPs, I believe. But that's a generalization and probably only pertains to the most common minerals found in water like calcium, magnesium, etc. It really depends on what's in the water. But if you can drink it and it's less than 50 ppm, it's probably safe for your plants.

Thanks Matt! Now my only quest is to find how much PPM is in my tap water, without a TDS meter Oh and my tap water is very drinkable. *crosses fingers and hope that my tap water is under 50 ppm

*possibly stupid question alert*

Is well water higher or lower in TDS than city water, generally?

I don't know how well water compares to city water "generally" (both can be very, very high), but well water in general is usually a poor choice to use for watering carnivorous plants due to the fact that when water comes in contact with the ground, it begins to take on minerals.

Atlanta, Georgia (about 3 miles north of the city in Midtown)
- Tap = 46 (wow! I was very surprised to see how low it is.)
- Collected Rainwater = 5 (collected last week)
- Kroger Distilled = 0 (cost less than 50 cents/gallon)

Hmm I wonder if anyone has results for New Zealand
I've been using tap water for my plants for 2 years , They seem to be growing very well as well

Tap Water 498ppm Middelburg South Africa... Our Neighbouring town Witbank is 2564ppm
Under sink Revearse Osmosis = 7ppm
RainWater = (Hasn't rained in a while)

Man, where's NY on this list.. lol

Time for me to purchase a TDS meter.

EDIT: Just checked the zero water website. Apparently Staten Island, NY - Tap Water reads 38! WIN!

If that's true, you are lucky, lucky, lucky! That's great.

I'll be purchasing a TDS meter, so I'll update in the near future.

Anyone any idea for a reading for Belgium?
