Elaine, I could not agree with you more. I have no source for rainwater and have no well. All my plants receive regular city tap water. The only variable is that while my orchids and other tropical plants are outside from April until October, they get rained on. Even then, they still get watered from my hose weekly and in really hot weather, bi-weekly. Five months out of the year while in the house, enclosed porch or greenhouses, they get nothing but tap water. I have over 400 orchids and over 100 miscellaneous tropical plants and they all do just fine.
