Well, in the first year of growing CPs my collection has grown quite a bit. In regards to Neps, I currently have 5 plants with 3 on the way. As such, watering all of these plants is starting to become somewhat of a concern. With my other CPs that must have pure water (such as sundews etc) I find myself buying lots and lots of water. Right now my main water consumers are my neps, as the other plants are generally small and sit in saucers that don't require that much water to fill. My question is, what ppm is considered ok for neps? I see different answers all over the web, from some claiming that anything up to 200 ppm is probably ok, and some saying you shouldn't go over 100 ppm, and others saying 0ppm is critical. Anyhow, I went to the aquarium store and bought a water tester. According to it, the GH of the water coming out of by bathroom is something around 75 ppm. Can I use this water for my neps, and possibly my mexi-pings and not have an issue? That will save me tons in water.
