I've read a little into peoples experiences using tap water for growing orchids. How the common advice of it being bad for them is mostly not true, and many highly succesful growers in places with very hard water like Florida water with hose water daily. My waters hardness is apparently around 260 ppm, so after reading that, I didnt think about it.
Then I saw someone talking about it on here, and they mentioned that its not necessarily the hardness of the water thats important, but the actual chemicals and minerals. So I took a look at some reports for my city's water, and its got me a bit worried. I dont really know what all the chemicals are, but it looks like I have a lot of concerning things in excess.
