Thanks for the reply... coir is the outer husk of the coconut: it is replacing fir bark in many orchid mixes due to the fact that it is readily available, long lasting and quite cheap. I use it mixed with a bit of dolomite or by itself for most of my cymbidiums. S/H is semi-hydroponic culture: for a better description than I can give you, look at this page

I do not think that you will have enough light in the location that you have described to reflower a standard sized cymbidium, additionally, most people keep their homes too warm at night to maintain cymbidiums once they are in low spike--you should certainly be able to initiate spikes were you to keep it outside over the summer/early fall (end of May-mid October), but unless you are able (read comfortable) with giving the plant consistent winter night temps in the mid 50's so the spikes can continue to develop, you most likely will not see any blooms. Nights up over 65F will cause rapid elongation of the spike, but no time for the buds within to properly develop. If I were going to try a cymbidium in your growing area, I would look for one of the "Chinese" types--probably Cym. sinense or Cym. ensifolium; both are much smaller plants that will bloom under warmer conditions. What they lack in flower size, they more than make up for in vigor and the great scent of their blooms. You might also look for any of the so called "teacup" cymbidiums, though they too will need more light than that found near an East window.
