I grow pretty much all of my potted plants in clear plastic, whether it's
"normal" culture using CHC/charcoal/perlite media or in semi-hydroponics.
The primary advantage to me is the ability to see how root grow is
progressing, the condition of the sub-surface medium, and whether or not
watering is necessary. In that last case, droplets of condensation on the
pot walls are a good indicator that there's plenty of moisture still available
to the plant.
The only negative - and a minor one that's easy to prevent - is the growth
of algae. Any time there is light, moisture, and nutrition, there WILL be
algae. While its major issue is aesthetic (although it does make the
observations in my early comments difficult), periodic dousing with a good
disinfectant (Physan or the like, or simply 1% bleach in water) keeps it
away.
Some will tell you that the greenhouse action of the clear pot leads to
burning the plants' roots, but 1) that's not likely with phalaenopsis light
levels, and 2) I've never seen that, even with plants grown in full sun.
