Hello all Growers, Hope you are all well. I did an experiment today and found out something quite interesting. Yes it is a lock down experiment I am mainly an indoor grower but all my Sarracenia, VFT and Darlingtonia are all outside and watered with rain water. I live in the North West of England. I grow three hybrids of Nepenthes in a window, a few Drosera binata in a window, a Ping in a window and a hell of a lot of Cephalotus in windows. I went peat free about three years ago. I straight switched coir for peat but always noticed a definite sulk in all my plants on re-potting.
I've been using the same old bag of peat moss since starting the hobby. But last week it ran out just before I got in an order of Plants... So based on advice seen on this forum I went out and got Shamrock branded peat, but I now think I've done something wrong, like get the wrong bag or something. My plants arrived in the post this morning and were all potted up and stuck in a terrarium with high humidity (instead of using a bag) and they all got top watered. But out of curiosity I checked the TDS of the water that collected in the bottom of the terrarium and it had gone from 7ppm to 62p
I'd like to pin down once and for all the infomation I'm picking up from the net about watering carnivorous plants with tap water. While I know it is bad for them and I still use filtered rain water for mine I have seen advice ranging from "It is ok now and again" to "YOU WILL TEAR APART THE FABRIC OF SPACE TIME IF YOU DO" well not that bad but have seen "Even a drop is a 100% kill for CP's". I know there are fancy filters on the market and such and even people saying to use deionised water (the type for car batteries and irons) at a push if stuck. But is tap water as a one off really that bad
