I'd be careful about making blanket statements about "orchids." There are some orchids that like a lot of water. I keep my phrags sitting in pure water. I let the water evaporate out and then refill the container. But certainly you can't do that with most orchids or you'll get root rot. When it comes to water, you need to look at the natural habitat for each species.
Just wanted to toss that in. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]
