Hi Sheridan,
Your s/h orchids look great!
I have all my phals in s/h and they love it too!
With regard to flushing the pot- I don't think you need to do it every other day, unless you reall want to.
I've not had any mineral deposit problems since I started flushing every second watering, other OB members flush every week.
BTW, cheap plastic jugs ($2.50) make great s/h containers for larger plants!
Happy growing!
