I recently returned home after 8 months I've been away for work just to find out that the person responsible for taking care of my CPs ignored most of my specific instructions and watered everything with tap water. My collection consists of Sarracenia, Drosera, VFT and nepenthes. To my surprise, ALL the plants seem to be in very good condition. Some seem to be even better.
Should I continue to use tap water or switch to distilled?
