I am not Jim, but I will tell you what I know about the compact and sub-compact Phalaenopsis orchids.
Though Phal. is a very minor segment of orchid plants I grow, I only grow the compact ones. That is due to two factors: They take up far less space and they are great candidates for mounting. I basically end up mounting all of mine. I like it that they are then presented the way they grow in nature.
Generally speaking, the Phal. I have grown over the years will be winter/spring bloomers. I have one in full bloom now, one with flowers and buds, and several that have stems/buds. As I said, I don't grow a lot of Phal. The nice thing about Phalaenopsis is that they can be in bloom for 2-3 months. The flowers are not only long-lasting, lasting longer in cool conditions, but it may take all the buds a month or even two to open.
The care of Phal. is pretty much the same as with most of my orchids. They like to be watered when their media dries out but can handle less than ideal watering, particularly if the humidity is relatively high. I am in Mississippi, so humidity is always high. My Phal. seem to form inflo. best when they are subjected to a drop in night temperatures into the low-60's to mid-50's. Since my orchids are in greenhouses during the fall and winter months, they get nice, warm daytime temps. and a 20-30F drop at night. I probably fertilize more regularly than the average grower, but do so with 1/4 the recommended rate in the fall and winter and 1/2 the rate in the spring and summer. I might fertilize every third or fourth watering.
Two things to beware of with Phal. At least this has been my experience and what I see lots of folks posting. If you grow your plant(s) in a pot, be sure that the plant is tilted to one side so that any water that gets into the crown will drain away. If water remains in the crown, crown-rot is likely and that can/may cause you to lose your plant. Also, my Phal. seem to attract scale. No other family of orchid seems to be a magnet for pests. Examine your plants regularly for pests, looking at the reverse side of the leaves and the stem for infestation. Good air circulation (I have four fans in each greenhouse) helps reduce pests and helps evaporate water. This single aspect is perhaps the most neglected by orchid (or other tropical plants) growers.
Here are some examples of compact and sub-compact Phal. All are mounted plants:
