I might go with the florists Oasis stuff . That's what's in the humidifiers anyway (they're round ones about the size of a Jammy Dodger biscuit).
You can get big bottles of distilled water cheap from motor factors (it's usually used for topping up car batteries)
I will buy more propylene glycol. I ran out, so have just been on pure water.
I calibrated the hygrometer with the bag of salt method and the wettest it said was 65 or 70, so I've been working on the "60 = 70" basis. Most of the time, though, it says 50. My flat is too warm I think.
