For some reason I always had problem keeping any pinguicula primulifloras alive. The primuliflora I got from Stephen had 3 plantleds so i decided to do some testing with them. All 3 plants were in the same tank and light but diff pots. I heard primuliflora pings like very very! acidic soil. One of the plants I water with distilled water only and for the other 2 I did mixed in a gallon of distilled water, 2 full teaspoons of white vinegar. I did water all 3 at the same time every time. Well after almost 2 months the loner plantled die about a week ago but the other 2 I did water with the mix of vinegar are doing amazing. I am almost thinking vinegar is acting as a fertilizer almost. Very robust fast growing Lil plants. I wish I had a camera handy.
I thought I would be nice to share this with everyone.

pH, I think, can be a bit misleading. I think buffering capacity is important too. My dehumidifier water should be "pure" water with a bit of dust and maybe a little bit of aluminum from the radiator fins. Its pH is around 3 but it's buffering capacity should be very low so it wouldn't be able to do much damage despite its low pH. Maybe it's like hot air and hot water. Hot water is more dangerous than hot air of the same temperature because of its higher specific heat.
Do you calibrate your meter Xavier? They can be a little troublesome if you don’t treat them right. The reason I ask is that distilled water should be a Ph of 7 not 5. You can buy calibration liquid at a hydroponics store or fish stoor in your case. I use a 7 and 4 to cal my Ph meter. I also store it in RO water. Never let the bulb dry out. Interesting though. I may have to give it a try.
If you are adding anything to distilled water to change the PH it wont take much to get a big movement. Although when you pour that water into the plant medium the medium will buffer the ph and move it closer to what the ph of the medium was.
What I do once and a while, is pore a little distilled water Ph 7 in the plant medium then catch the first 20mils or so tat runs out the bottom and measure with your PH meter. This will tell you if the medium is acid or alkaline. Keep up the testing. Stephen
I didn't mean to suggest that the pH measurement was incorrect. Just that it would take very little of an acid or base to change the pH of pure water. Also after this water is added to any media especially organic it would essentially be the same pH as the media itself because of the media buffering ability, as mentioned above. It's hard to imagine that a very dilute acetic acid solution could change the pH of a partly organic medium (peat moss).
