Hello all-

Does anyone know of an inexpensive way to improve water quality for orchids?

In my apartment the tap water seems to be high in minerals and i have a feeling my orchids are not loving it. i use a charcoal filter (like brita) for my own water consumption. would charcoal filtration be good for orchids? Can anyone suggest anything else?

I've heard rainwater is the best but i cant collect it.

Please advise, thanks!
