cats won't bloom

[Brookpoint]

I have about 30 cats, all look healthy, nice and green, unfortunately, all are noids. When I started growing orchids i didnot know that the tags with their names were important, so dumb me all are missing.
That said I now take my orchid growing very seriously and have been giving them tlc, for over a year or two. Bright llight under a screened cage, with several hours of sun. I seem to have the watering and feeding down, not loseing any to drought or flood. lots of new roots and growth but no flowers. Several have made sheaths that then dry up with no flower. I have searched the board and read everything i can find, but have no idea how to acheive bloom. One plant produced two blooms earlier this fall, around October, otherwise nada. I have 5 vandas in bloom at the moment, beautiful, and several of my phals are spiking. Any suggestions.??
