That's pretty much what has been working for me, too. I like s/h so far although I'm only using it for the smaller plants that were so hard to keep watered. I think there is a reasonable margin for error since the media retains moisture for a while after the reservoir is dryed out. For me it gives about a week between watering sessions. And then sometimes I haul them to the sink for a good flushing of the media, and sometimes, if I'm pressed for time, I simply top off the reservoir. Pretty flexible.

And one sickly phal that I had about given up on put on a new leaf right away when it went into s/h!
