Southern California Water, Tap Vs. R/O

[lenny]

I'm located in Southern California, La Mesa Area. I'm new to
the orchid scene, about 7 months. I grow outside in a shade house and use R/O water. My problem is that I spend
numerous hours watering plants and buying water. I'm retired and would like to spend some valuable time on other
projects, drinking coffee, reading the newspaper and watch
my plants grow.

I've been told tap water is bad for your orchids in La Mesa,
and I am not ready to setup a R/O filter system for these
critters. So if you from my neck of the woods and using
regular tap water how about some advice for a rookie.

My orchids are doing well with R/O water but I convienced
the soft spray of a garden hose is the way to go for me.
