Types of water for plants
I have had several tillandsia for quite a few years. I mist them with water as one is supposed to, but I have a question about the type of water and using. I have always used filtered water from our water filter. It takes the chlorine out but none of the minerals that I know of.
I was reading that one should water tillandsias with either de-mineralized water or rainwater. Rainwater is not an option for me. I don't know how to get de-mineralized water other than distilled water. I've also read that one should not use distilled water on plants or with tropical fish. Something about the salts and minerals that is needed by all plants and animals that most water coming up the tap provides.
My question is, is this information about distilled water a fact or myth? I know that there's calcium in my drinking water and the tillandsias, that I mist in the terrarium, are being exposed to that calcium, because there is a calcium buildup on the inside of the terrarium after over six years in existence.
Thanks for any information!
