Here is what I wrote to Bob of Albany NY....
No not everyday. The beauty of it for me, i can water everything when its time to water. So basically I have 3 pot conditions, semi hydro for 90% of the Phrags, orchiata mix for most Paphs and other genera, clay pots/ balls for Brachys/some Parvi hybrids. The Cattileyas are in clay or wood baskets with orchiata mix. The bottom line, everything dries at a different rate so I can water everything at the same time.
In general about every 4th day in the winter months moving to evey other day or 3rd in the summer. All dependent on the outside weather.
I killed so many Brachys due to basal rot trying to grow in plastic pot with organic mixes. A couple of references lead me it this direction. An old AOS magazine from the 60s had an article on growing Brachys. The guy would wait until his leaves would wrinkle on the top surface when he lifted one up from the tip before he would water them. That's dry! He was using plastic and organic. One of our own ST members a couple of years ago posted his bellatulum, multiple growths, beautiful flowers and growing it under lights in a plastic pot with nothing but hydro stones. It had a massive root system. There is algae growing on the outside of the clay pots so they do get water.
