There is no problem with glazed pots... you will be fine. I think it is a misconception. Look at my yellow phal in a glazed pot, no problem. Its been in continuous bloom for around three years. I have several phals in glazed pots. (I didn't choose the pots, my mom used them since I was young. I am using one of her old pots. One of my oldest phal has been in the same glazed pots for many many years)
At one time plastic pots were thought of being evil...lol
The glazed pots are just not porous like unglazed pots. Air does not move though the clay. Use some airy growing media like bark mix and you will be fine. Hey, plastic pots are just as poor with air movement, and people use sphag in them...a media that doesn't have the same air movement as bark
