Phalaenopsis not flowering

[Leslie Jones]

, I am somewhat new, I have 6 orchids, and have not fussed much to get them to flower, they are on a southwest windowsill in my kitchen/family room. I do have a small Phalaenopsis, in a tiny clear glass fish bowl type vase (purchased at grocery store in vase). When I purchased it had two flower spikes (June 2014). It seems to be very healthy, but is producing leaves like crazy. No flower spike yet, I have it on my desk in the office, and it does get some natural light but no direct sunlight.
