Just to clarify, low-e glass does not cut down ONLY wavelengths "that allow
blooms". The coating's primary function is to block long-wave infrared
(heat), but unfortunately has a side effect of suppressing the light fairly
uniformly accross the visible spectrum.

As an example, the earlier generations Low-E coatings, (using fluorine-doped
tin oxide at about 3000 angstroms thickness, dropped the intensity by about
20% in the wavelengths that count for plants. More modern coatings tend to
be thicker and of different chemistry, so I'd guess we're looking at
"permanent shade cloth" at least 40%-50%.

I sometimes wonder if the new dual pane windows aren't the culpret in these
plants not flowering. All that low e glass cutting down on the wave
lengths of light that allow blooms. Because otherwise, if you are giving
it that amount of light (light is usually the limiting factor, poor light
= no blooms), you are doing OK as far as I'm concerned. Does it get a 10
degree change in day/night temperature? It wants that too. Otherwise the
feeding is OK. If you get really into this hobby we can tweak feeding, but
right now, as I say, the limiting factor is light. More light -not direct
light - = blooms.

Sometimes these are really forced into bloom at the nursery and require a
few years rest before they'll bloom again, too. So that may be why it
ain't a blooming fool for you.

I live in New Jersey and keep it on the window sill and it gets about 5 or
6
hours a day we have central air condition and it is cool in the house it
is
in orchid soil which doesn't look like soil but it is orchid soil as per
the
packaging we use orchid food according to packaging again it looks very
healthy but no flowers.
Thanks Again

Okay, this is a Phalaenopsis (can tell by the name). Please tell us your
growing conditions: where you are, where the plant is, what the temps
are,
etc. Then we can help, and will be glad to do so.

Just as general information, however, Phalaenopsis do not like very
sunny
locations, and it is quite normal for them to lose old leaves as the new
ones grow.
